How Many Maternity Clothes Should You Really Buy? What Other Mums Say

Search this question and you'll find a dozen lists all confidently naming a number: "5 tops, 3 bottoms, 2 dresses." But the real experiences shared by women who've actually done this — in blogs, newsletters, and a commissioned industry survey — don't agree with each other at all, and that disagreement is itself the most useful piece of information here.

A survey commissioned by maternity brand Isabella Oliver — a 500-mother brand-commissioned survey, independently reported by Yahoo Life UK — found that expectant mothers buy an average of 21 items of maternity clothing, spending roughly £700, including two pairs of jeans and three pieces of underwear — and that the clothing is typically only worn from around 16 weeks into pregnancy until about five weeks postpartum. A meaningful share of that wardrobe doesn't stay in use long: over a quarter of respondents said they pass their maternity clothes on to friends or family, three in ten donate them, and one in ten simply throw them away.

Compare that to a three-pregnancy personal account from a blogger writing at Isn't That Charming, who built a 20-piece maternity capsule gradually across three separate pregnancies — but in her most recent pregnancy specifically, bought only four new items, filling the rest with pieces she already owned and hand-me-downs from a friend. Buying four new items is not the same claim as managing on four maternity pieces total; the rest of her wardrobe came from what she already had. She also makes a specific, useful observation: in her experience, there are really only four to five months of a pregnancy where maternity-specific clothing is needed at all.

At the more minimal end, a minimalist personal account from a writer at the Substack newsletter "Everything I Wore Pregnant" described selling 65% of her existing wardrobe on Poshmark and deliberately buying just a handful of maternity pieces — three pairs of leggings in different colours, three tank tops with a built-in bra, and one bodysuit — then wearing that small rotation on repeat for essentially the entire pregnancy. A separate remote-working personal account, from a writer working from home throughout her pregnancy, described rotating through four maternity leggings and her husband's old T-shirts on most days, crediting her low spending largely to not needing to dress for an office.

None of these women are wrong, and none of them are following a universal rule. They simply have different laundry habits, different budgets, different access to hand-me-downs, and different amounts of time spent somewhere clothes are seen by other people. That's the actual variable driving the number — not a fixed formula anyone has published before.

The accounts above point to a practical question that fixed shopping lists tend to miss: how many days can you go before you run out of clean options, given how often you're personally comfortable re-wearing each type of clothing? Several accounts describe relying repeatedly on a small number of leggings or jeans, but how often those specific pieces were washed isn't consistently reported. That personal re-wear tolerance — which varies by category and by person — is what actually determines how many pieces someone needs, not a flat number anyone can responsibly assign on your behalf.

Below is a worksheet built on that logic, rather than a fixed list — designed to be printed and filled in with your own numbers.

• Step 1: Fill in how many days typically pass between your loads of laundry.
• Step 2: Fill in your own honest number for how many times you're personally comfortable wearing each category before it needs washing — this is a personal preference, not a number MAMANIDA can responsibly assign for you.
• Step 3: Divide days by re-wears, round up, and add an optional buffer piece for laundry delays or an unexpected day out.

For example: imagine you do laundry every seven days and are comfortable wearing maternity bottoms three times between washes. 7 ÷ 3 = 2.3, which rounds up to 3. Adding one optional buffer pair would give you 4 bottoms. This is an illustration of how the calculator works, not a recommended number — your own laundry interval and re-wear comfort will very likely be different, and that's exactly the point.

Across the accounts we reviewed, several categories appeared repeatedly: comfortable bottoms, supportive or maternity-specific underwear where needed, versatile tops or dresses, and layers that could continue working as the body changed. Not everyone needs all of these — a fully remote pregnancy with no office to dress for, for instance, changes the calculation considerably. See MAMANIDA's guides on building a maternity capsule wardrobe and choosing maternity jeans by trimester for more on selecting specific pieces if any of these categories are on your list.

If your number ends up smaller than you expected, the accounts above suggest that's a well-documented outcome, not a sign you're under-shopping — and if it ends up larger, the same survey data shows plenty of company eventually passing those pieces on rather than needing them forever.

Once your calculator gives you a number for each category, you can compare specific maternity jeans, tops, and dresses across brands on MAMANIDA, filtering by price, size, and colour.
