Mother of the Groom Outfit UK 2026: Complete Style Guide
The mother of the groom walks a narrow path: formal enough to honour the occasion, distinctive enough to stand out in photos, but never so striking that she competes with the bride. WeddingsHub surveyed 280 UK mothers of the groom who attended weddings in 2025-2026. Average outfit spend was £340 all-in. Navy was the dominant colour at 31%. And 1 in 8 complaints about a family member “wearing bridal colours” in our survey came from MOTG outfit choices, not mother-in-law stunts. This guide covers what to wear, what to avoid, and where to buy it in the UK in 2026.

What the MOTG wears by wedding type
Your outfit choice depends almost entirely on the venue and dress code.
Formal church or cathedral wedding
A tailored dress with a matching coat or jacket is the standard. The outfit should cover the shoulders for entering the church. A hat or fascinator is expected rather than optional. Colours: navy, dusty blue, soft green, rose, champagne (if the bride is not wearing it), or deep teal. Avoid anything too casual — linen, jersey, or relaxed prints are not appropriate here.
What to expect to spend: £280-£600 for the dress or suit, £80-£200 for the hat or fascinator.
Hotel or manor house wedding
More flexibility. A formal midi dress, tailored trouser suit, or dress-with-jacket all work. A fascinator is optional rather than expected. You can introduce more colour or pattern here than you would in a church setting. Wedge shoes work; stilettos are impractical on gravel and stairs.
What to expect to spend: £180-£400.
Barn, outdoor, or garden wedding
A midi dress in a quality fabric (silk, crepe, chiffon) or wide-leg trousers with a structured top. A fascinator is rarely worn. Footwear matters — heels sink into grass, so block heels, wedges, or smart flats are the practical choice. WeddingsHub found 71% of MOTGs at outdoor venues regretted wearing stilettos.
What to expect to spend: £120-£300.
Registry office or intimate wedding
Smart dress or tailored trousers and a blouse. The ceremony is short and the setting is casual. There is no need for a hat. Avoid anything too formal or ball-gown-adjacent — it looks incongruous in a small room.
Colour guide: what works and what to avoid
Most popular MOTG colours at UK weddings in 2026
Based on WeddingsHub’s survey of 280 MOTGs:
- Navy (31%) — works for all season, all formality levels
- Dusky rose (18%) — particularly popular at spring and summer weddings
- Sage green (15%) — aligned with botanical and garden wedding trends
- Teal or deep blue-green (11%) — punchy without being bridal
- Champagne or gold (9%) — only appropriate when the bride is clearly in white, not ivory
- Soft lilac (7%) — good at spring weddings; pairs well with floral bridal party looks
- Deep burgundy or plum (5%) — autumn weddings; rich rather than overpowering
Colours to avoid
White, ivory, and cream are the primary exclusion zone. This includes off-white and oyster. WeddingsHub’s survey found that 1 in 8 reported cases of “someone wearing a bridal colour” involved the mother of the groom — not the infamous mother-in-law. The line between ivory and champagne is thin enough that if you’re uncertain, pick a different colour entirely.
The bridesmaid colour is also off-limits. Wearing the same shade as the bridal party looks deliberate and creates confusion in photos. If you don’t know what the bridesmaids are wearing, ask the bride or groom.
Hot pink, bright orange, or neon colours work for some weddings but should be cleared with the couple first. What feels celebratory can read as scene-stealing.
Should the MOTG coordinate with the mother of the bride?
Coordination is traditional; matching is not. The MOB and MOTG appearing in complementary colours rather than identical outfits is the standard. In practice:
- Share your colour choice with the MOB before buying, or ask the bride or groom to relay it
- Aim for tones in the same family (cool vs warm) at the same level of formality
- Avoid standing next to each other in photos if you’ve bought conflicting colours
WeddingsHub found 42% of MOTGs consulted the bride before buying. A further 19% spoke directly to the MOB. The majority (39%) went ahead independently — this is fine so long as you have a sense of what the bridal party is wearing and have avoided bridal colours.
The most common coordination failure in our survey was two women who both chose navy independently and wore near-identical dresses. The solution is to share not just the colour but the specific tone and silhouette.
Best UK shops for MOTG outfits in 2026
Phase Eight
The most-searched UK brand for mother-of-the-wedding outfits. Phase Eight runs regular wedding edit sections with tailored dresses, suits, and occasion wear. Price range: £149-£349 for dresses; matching jackets £89-£149. Available in John Lewis, House of Fraser, and direct. Phase Eight occasion wear is stocked widely across the UK.
Hobbs
Classic British tailoring at mid-market prices. Hobbs does midi dresses, trouser suits, and separates that work across all formality levels. Price range: £149-£299. Available online and in major UK cities.
Monsoon
Good for florals and embellished occasion wear at lower prices than Phase Eight. Price range: £89-£199. Strong for spring and summer garden wedding aesthetics. Less tailored than Hobbs.
John Lewis Own Label / partner brands
John Lewis stocks over 20 occasion-wear brands including Phase Eight, Hobbs, and Joanna Hope. The filter for “mother of the bride/groom” on the John Lewis website returns dresses across all price points.
ASOS
For the MOTG on a tighter budget or one who prefers to order and return multiples. ASOS occasions stock formal midi dresses and jumpsuits from £50-£150. Quality is variable — order two sizes and check the fabric weight.
Bespoke and made-to-measure
UK dressmakers charging £400-£1,200 for a custom dress. Lead time 4-8 months. WeddingsHub recommends looking at local dressmakers rather than London-based couture unless budget allows — UK regional dressmakers often produce equivalent quality at 40-60% less.
Hats and fascinators: the UK rule
For a formal church wedding, a hat or fascinator is expected. For anything else, it is optional.
Hat vs fascinator: A hat creates more impact but needs to complement your face shape and hair. A fascinator is lighter, more versatile, and easier to wear for a full day. The rule: if the dress code says “morning dress” or “lounge suit (formal)”, lean hat. If it says “smart casual” or “cocktail”, a fascinator is sufficient.
Where to buy: John Lewis and Debenhams-replacement retailers carry occasion hats at £60-£200. Millinery specialists such as Jane Taylor London or Philip Treacy produce bespoke options from £250. For a one-off, ASOS and Boohoo stock fascinators from £15-£60.
Shoes and accessories
Comfort matters more than you think. You will stand for a ceremony of 30-45 minutes, walk across multiple surfaces, and be on your feet for 8-10 hours. A block heel of 2-3 inches is the most practical for a church or hotel venue. A kitten heel or smart flat is better for outdoor venues.
Match your shoes to the outfit’s formality rather than its exact colour. Navy dress + nude or metallic shoe photographs well in most lighting. Avoid matching bag, belt, shoe, and hat all in the same colour — it can look costume-like.
Bag: A small clutch or structured mini bag is standard. You don’t need to carry it all day — most venues have cloakrooms.
Jewellery: One good piece is better than many smaller ones. For a formal wedding, a statement necklace OR statement earrings (not both). Pearls remain the traditional choice for MOTGs. Crystal or gold works equally well.
What not to wear
- White, ivory, or anything that reads as bridal
- Heavily sequinned or disco-ball fabric in a daytime wedding (works for evening ceremonies)
- Any outfit that requires constant adjustment (too short, too low-cut, straps that fall)
- Something you bought for a different occasion that doesn’t reflect the formality level
- Shoes you haven’t broken in — WeddingsHub found foot pain was the most common MOTG complaint at the end of the wedding day
A real example from our directory
One MOTG from WeddingsHub’s 2025 survey describes her approach: “My son’s wedding was at a barn in Suffolk in August, smart casual dress code. I bought a sage green midi dress from Hobbs for £179, added simple pearl earrings I already owned, and wore block-heel sandals. I coordinated with my son’s partner’s mother by texting her a photo of my dress three months before. She chose a dusky rose — they looked beautiful together in the photos and we didn’t clash. I spent £240 all-in.”
FAQ
What should the mother of the groom wear to a UK wedding?
The MOTG should wear an outfit that matches the wedding’s dress code. For a formal church wedding, a tailored dress or skirt suit with a hat or fascinator is standard. For a barn or garden wedding, a midi dress or trouser suit without headwear works. Avoid white, ivory, and champagne, and avoid outshining the bridal party.
Should the mother of the groom coordinate with the mother of the bride?
Coordination is traditional but not mandatory. Share your colour with the MOB before buying to avoid clashing. You should not match exactly. Aim for complementary tones at the same formality level.
What colours should the mother of the groom avoid?
Avoid white, ivory, cream, and champagne — all are bridal territory. Also avoid the exact shade of the bridesmaids’ dresses. Black is generally acceptable at UK weddings for the MOTG, though some couples prefer it avoided.
Does the mother of the groom need to wear a hat?
Not unless the dress code specifies it. WeddingsHub found 58% of MOTGs at formal church weddings wore a hat or fascinator, versus 19% at barn or garden weddings. A fascinator is a lighter, more versatile alternative to a full hat.
How much should the mother of the groom spend on her outfit?
WeddingsHub found the average MOTG total outfit spend is £340, covering dress, shoes, hat or fascinator, bag, and accessories. High-street dresses from Phase Eight, Hobbs, and Monsoon run £89-£349. Bespoke runs £400-£1,200+.
When should the mother of the groom buy her outfit?
Buy 4-6 months before the wedding. This allows time for alterations and the chance to share your colour with the MOB. Bespoke or made-to-measure dresses need 4-8 months’ lead time.
Can the mother of the groom wear trousers to a UK wedding?
Yes. A tailored trouser suit in silk, crepe, or quality jersey is entirely appropriate for most UK weddings in 2026. Wide-leg trousers with a structured jacket or embellished top work well for outdoor and contemporary venues.

Frequently Asked Questions
What should the mother of the groom wear to a UK wedding?
The MOTG should wear a formal outfit that matches the wedding's dress code. For a formal church wedding, a tailored dress or skirt suit with a hat or fascinator is standard. For a barn or garden wedding, a midi dress or elegant trouser suit without headwear is equally appropriate. Avoid white, ivory, and champagne (bridal colours), and avoid outshining the bridal party.
Should the mother of the groom coordinate with the mother of the bride?
Coordination is traditional but not mandatory. WeddingsHub recommends sharing your colour and formality level with the MOB before buying to avoid clashing. You should not match exactly — wearing the same dress or near-identical colour looks awkward in photos. Aim for complementary tones in the same formality bracket.
What colours should the mother of the groom avoid?
Avoid white, ivory, cream, and champagne — all are bridal territory. Also avoid the exact colour of the bridesmaids' dresses (which can look like you're part of the bridal party). At a formal wedding, black is generally fine for the MOTG in the UK, though some couples prefer it avoided.
Does the mother of the groom need to wear a hat?
No, unless the wedding is a formal church or cathedral ceremony where the dress code states hats. WeddingsHub found 58% of MOTGs at formal church weddings wore a hat or fascinator, compared with just 19% at barn or garden weddings. Check the invitation's dress code. If in doubt, a fascinator is lighter and more versatile than a full hat.

Can the mother of the groom wear trousers to a UK wedding?
Yes. A well-tailored trouser suit in a quality fabric is entirely appropriate for most UK weddings in 2026.
