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

Search this question and you'll find a dozen lists confidently giving you 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. That disagreement is actually the most useful piece of information here.

A survey commissioned by maternity brand Isabella Oliver — a brand-commissioned survey of 500 mothers, independently reported by Yahoo Life UK — found that expectant mothers buy an average of 21 maternity clothing items, spending roughly £700, including two pairs of jeans and three pieces of underwear. It also found that the clothing is typically worn only from around 16 weeks into pregnancy until about five weeks postpartum. A meaningful share of that wardrobe doesn't stay in use for long: more than 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 with a personal account spanning three pregnancies from a blogger at Isn't That Charming. She gradually built a 20-piece maternity capsule across three separate pregnancies — but during her most recent pregnancy specifically, she bought only four new items, filling out the rest with clothes she already owned and hand-me-downs from a friend. Buying four new items isn't the same as getting through pregnancy with only four maternity pieces total; the rest of her wardrobe came from what she already had. She also makes one particularly useful observation: in her experience, there are really only four to five months of pregnancy when maternity-specific clothing is needed at all.

At the more minimalist end, a writer behind the Substack newsletter "Everything I Wore Pregnant" described selling 65% of her existing wardrobe on Poshmark and intentionally buying just a handful of maternity pieces — three pairs of leggings in different colors, three tank tops with built-in bras, and one bodysuit — then repeatedly wearing that small rotation for essentially the entire pregnancy. In a separate personal account, a writer who worked remotely throughout her pregnancy described rotating through four pairs of maternity leggings and her husband's old T-shirts on most days, attributing her low spending largely to not having 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 in situations where their clothes are seen by other people. Those are the variables actually driving the number — not a fixed formula someone can publish for everyone.

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, based on how often you're personally comfortable re-wearing each type of clothing? Several accounts describe repeatedly relying on a small number of leggings or jeans, but they don't consistently report how often those specific pieces were washed. Your own tolerance for re-wearing — which varies by clothing category and from person to person — is what actually determines how many pieces you need, not a flat number anyone can responsibly assign to you.

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

• Step 1: Enter how many days typically pass between loads of laundry.
• Step 2: Enter your own honest number for how many times you're comfortable wearing each category before washing it — this is a personal preference, not a number MAMANIDA can responsibly choose for you.
• Step 3: Divide the number of days by the number of 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 gives you 4 bottoms. This is an illustration of how the calculator works, not a recommended number — your own laundry schedule and comfort with re-wearing will very likely be different, and that's exactly the point.

Across the accounts we reviewed, several categories came up repeatedly: comfortable bottoms, supportive or maternity-specific underwear when needed, versatile tops or dresses, and layers that could keep working as the body changed. Not everyone needs all of these — for example, going through pregnancy while working fully remotely with no office dress code 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 that you're buying too little — and if it ends up larger, the same survey data shows that plenty of people eventually pass 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 color.
