Maternity wardrobes in Britain have changed more in the last three years than in the two decades before. The 2024 collapse of Seraphine’s retail arm, the rebranding of Isabella Oliver after its lifestyle pivot, and the quiet dominance of H&M Mama on the high street have reset what a pregnant professional actually buys. Our editors spent the autumn working through current UK stock across all three labels with pregnant staffers and freelance contributors in trimesters one, two and three. Prices quoted are the current retail at time of writing and reflect the autumn 2026 UK ranges.
What this piece sets out to answer is simple. If you have £300 to £800 to spend across nine months, which brand earns its place in a working wardrobe, which belongs in loungewear, and which is the smart cost-per-wear buy once the newborn phase ends. The three labels sit at different price points (H&M Mama from £12 to £49, Seraphine from £49 to £149, Isabella Oliver from £85 to £295) and each has quietly repositioned since 2023. We also note where secondhand on Vinted and eBay changes the maths.
The State of UK Maternity in 2026
Three forces are shaping maternity fashion right now. First, workwear has fragmented: fewer British mums return to a daily office, so the demand is for pieces that work on video calls three days a week and school runs the other two. Second, resale value has become part of the purchase calculation, and this favours brands with recognisable silhouettes. Third, hybrid pieces (nursing-ready tops, high-waist jeans that transition postpartum) have moved from a nice-to-have to the default expectation.
Price per wear becomes the honest metric. A £295 Isabella Oliver tailored dress worn 20 times before resale at £120 nets a cost per wear of £8.75. A £49 Seraphine nursing top worn 60 times nets 82p. An H&M Mama vest at £12 worn 40 times nets 30p but will show it. The three brands win on different maths and the mix matters.
Isabella Oliver: Premium British Tailoring
Isabella Oliver is the London label that redefined maternity dresses in the mid-2000s and has quietly held the premium slot since. The 2024 brand refresh moved the house palette to deep burgundy, forest, cream and ink navy, with an emphasis on tailored jersey and ponte-roma dresses. UK retail runs £85 (ruched tees) to £295 (tailored jacket dresses), with most pieces at £145 to £195.
Where Isabella Oliver Wins
Fabric and cut. The Oliver signature is a bias-cut viscose or ponte-roma jersey that drapes around the bump without clinging to it, and the ruched side seams genuinely accommodate growth from 20 to 40 weeks without re-sizing. Workwear credibility is high: these are the dresses senior lawyers and consultants actually wear through a pregnancy. Resale value on Vinted holds at 40 to 55 percent of retail, which is exceptional for maternity.
Where Isabella Oliver Falls Short
Price. There is no getting around £195 for a wrap dress even on a 30 percent sale. Range is narrow outside dresses and tailoring; if you want jeans, chinos or casual separates, Oliver has very little. Returns can be slow, our editors recorded eight to twelve working days against the advertised five. The brand is online-only in the UK, so you cannot try on in-store.
Seraphine: The Reset Mid-Market
Seraphine’s retail collapse in late 2024 was a shock, but the brand relaunched online under new ownership in mid-2025 with a tighter range. The current line sits at £49 to £149, with a clearer focus on nursing-friendly dresses, denim and loungewear. The famous “Meghan Markle” wrap dress is back, now at £119 (down from £149 pre-collapse).
Where Seraphine Wins
Nursing integration is the strongest in the category. Discreet zip and overlay openings on dresses and tops mean the garment works through pregnancy, nursing and beyond. The denim is cut for the UK high street with real stretch and a decent rise, something Isabella Oliver does not offer. Prices after the relaunch are more honest, and midweek sales regularly hit 25 to 35 percent off.
Where Seraphine Falls Short
The post-relaunch stock issues continue. Our editors had three items on back order between June and September, with no clear restock date. Fabric quality has slipped versus the pre-2024 range; two tops pilled within six washes. Returns process is clunky and still routes through a third-party courier. The famous wrap dress is a step down in weight versus the pre-collapse version.
H&M Mama: The High-Street Backbone
H&M Mama is the quiet workhorse of British maternity wardrobes. Stock refreshes every four to six weeks, prices run £7.99 (basics) to £49.99 (occasion dresses), and the fit is more generous than the rest of the H&M line. Nursing-compatible pieces are clearly tagged in both the app and the Oxford Street flagship.
Where H&M Mama Wins
Price and availability. A full capsule of basics (two leggings, three tees, one jumper, one dress) is £95 to £120 for the whole set. Over-bump jeans at £29.99 are honestly comparable to brands charging four times that. In-person try-on at any larger H&M, same-day pickup, and a 30-day return policy that actually works are rare in the maternity space.
Where H&M Mama Falls Short
Fabric longevity. Most pieces are built for a single pregnancy and will not survive postpartum re-wear. Workwear is thin; the limited blazer and trouser line is more “smart casual” than “boardroom”. Nursing openings on tops look obvious once you know the hack. Online stock is unreliable; our editors flagged five items as “available” that were out of stock when they tried to buy.

Pros and Cons
Isabella Oliver
Pros
The tailoring is the best in UK maternity full stop, with ruched jersey dresses that genuinely accommodate 20 weeks of growth without pulling. Workwear credibility is unmatched for client-facing roles and resale value holds exceptionally well on Vinted and eBay. The 2024 autumn palette (burgundy, forest, ink) is deliberately versatile.
Cons
Pricing is punchy and the range is narrow outside dresses and tailoring. Online-only in the UK means no in-store try-on, and returns can take over a week. Casual separates and denim are weak points; you need to shop elsewhere for jeans, loungewear and the school-run end of the wardrobe.
Seraphine
Pros
Nursing integration is the smartest in the category, with discreet overlay and zip openings that make a dress useful from 12 weeks through the first six months postpartum. Denim is well cut for British sizing with real stretch and a decent rise. The relaunched price points are more honest than the pre-2024 range.
Cons
Stock issues continue through 2026, with popular items on back order for weeks. Fabric quality has slipped versus the pre-collapse range; some tops pill within six washes. The returns process is slower than it should be and the famous wrap dress is noticeably lighter in weight.
H&M Mama
Pros
Unbeatable value for basics, with a full capsule under £120. Weekly stock refresh keeps the range current and over-bump jeans at £29.99 are the surprise win of the collection. In-person try-on, same-day pickup and a working return policy are rare for maternity.
Cons
Fabric longevity is limited, with most pieces not surviving into postpartum. Workwear is light, with few genuine boardroom options. Online stock accuracy is poor, and nursing openings on tops look visible once you know what to spot. Buy for the pregnancy months, do not expect items to last beyond.

Frequently Asked Questions
Q: How much should I budget for maternity clothes in the UK
Most working mums spend £350 to £600 across the pregnancy, including workwear, casual and occasion wear. The sensible split is £180 to £250 on two or three premium tailored pieces (Isabella Oliver, Boob Design, or Seraphine wrap dresses), £120 to £180 on H&M Mama basics, and £50 to £100 on secondhand pieces from Vinted. Spending under £200 total is achievable with heavy H&M and secondhand reliance.
Q: When do I actually need maternity clothes
Most mums need maternity jeans or over-bump leggings from week 16 to 20, and dedicated maternity tops from week 20 to 24. Workwear and dresses tend to be bought earlier (week 14 to 16) because meeting photos and video calls expose the bump sooner. First pregnancies tend to show two to four weeks later than second or third.
Q: Is nursing-compatible clothing worth the premium
Yes, if you plan to breastfeed or combination feed past six weeks. A dress or top that accommodates both bump and nursing access is used across 12 to 18 months rather than six. Seraphine, Boob Design and Isabella Oliver all do this well; H&M Mama does it adequately on tops but poorly on dresses.
Q: Which brand resells best
Isabella Oliver by a clear margin. A used Oliver tailored dress in good condition sells for 40 to 55 percent of retail on Vinted, which is exceptional. Boob Design holds at 30 to 40 percent. Seraphine resale has slipped since the retail collapse and sits at 20 to 30 percent. H&M Mama has effectively no resale value, pieces sell for £3 to £8 on Vinted regardless of original price.
Q: Can I wear non-maternity clothes through pregnancy
Through the first trimester, yes, with careful choices. Jersey wrap dresses, elastic waists, oversized shirts and most leggings last to week 16 or 18. After that, over-bump support becomes a real comfort factor on jeans and tailored trousers. Some mums get away with low-rise or elasticated non-maternity through week 24 with a bump band from Bravado or Belly Bandit.
Q: Is Isabella Oliver worth the money for a four-month wear
If you resell after, yes, net cost per wear lands in the £6 to £10 range on a tailored dress. If you keep for a second pregnancy, the price falls to £3 to £5 per wear. If you plan a single pregnancy and will not resell, think carefully; H&M Mama plus one Seraphine piece covers most needs for under £200 total.
Q: What about renting maternity clothes
Hurr Collective and By Rotation both offer selective maternity pieces, mostly Isabella Oliver and Boob Design, at £20 to £45 per week. This can work for a single occasion dress (a wedding, a conference) but is rarely cost-effective for daily wear. Resale typically beats rental across a full pregnancy.
