Your Pregnancy Wardrobe: What to Buy, What to Borrow, and What Already Fits

There is a very specific moment in early pregnancy when you try to button your favourite jeans, and the button just... does not reach. Not even close. You do the hair-tie trick. You leave them unbuttoned under a long top. You briefly consider buying a second pair in a bigger size before realising you will outgrow those within a fortnight too.

Welcome to the pregnancy wardrobe puzzle. And honestly? It is one of the most confusing parts of pregnancy that nobody really prepares you for. Because maternity sections online will have you believing you need an entirely new wardrobe in stretchy black fabric, and your Instagram feed is full of women in perfectly draped bump-hugging dresses that cost more than your weekly shop.

The truth is somewhere in the middle. You need far less than you think, but the few things you do buy will earn their place a hundred times over. Here is exactly what to spend on, what to borrow, and what is already hiding in your wardrobe. 👗

The Bottoms Situation

This is where most of your maternity budget should go, because bottoms are the first things that stop fitting and the hardest to hack with what you already own.

What to buy: Two pairs of maternity jeans or trousers with the over-bump band. Yes, the ones with the big stretchy panel. They look ridiculous on the hanger and absolutely brilliant on your body. One pair in your usual colour and one pair in black will see you through work, weekends, and everything in between. If you are pregnant through summer, swap one pair for maternity shorts or a pair of linen trousers with a stretchy waist.

What to borrow: Maternity leggings. Everyone who has been pregnant owns at least three pairs, and most are in perfectly good condition because they stretch. Ask around. Your sister, your friend, your colleague from two desks over. Maternity leggings are the most borrowable item of clothing in existence.

What already fits: Joggers, tracksuit bottoms, anything with a drawstring or elasticated waist. Your partner's joggers, specifically, if they are a size or two bigger. These become your evening uniform from about week 20 onwards, and there is absolutely no shame in that.

Tops That Actually Work

Good news: you need to buy far fewer maternity tops than the shops want you to believe.

What to buy: Two or three good-quality maternity tops. Look for ones with ruching at the sides, because they grow with you and still look shaped rather than tent-like. A Breton stripe maternity top is basically a uniform among pregnant women for a reason: it works with everything, always looks put together, and the horizontal stripes genuinely look good on a bump. One long-sleeve and one short-sleeve is enough.

What to borrow: Anything oversized that your non-pregnant friends or family have grown tired of. Oversized blazers, boyfriend-style shirts, chunky knits. The relaxed fit that looked intentionally baggy before now looks effortlessly chic draped over your bump.

What already fits: More than you expect. Stretchy vest tops, loose t-shirts, anything with a bit of give in the fabric will carry you surprisingly far into pregnancy. Your normal size in a stretchy cotton top often works right through to the third trimester if the cut is generous. Try everything on before you go shopping, because you might not need as much as you think.

The Dress: Your Pregnancy Best Friend

If there is one item worth investing in properly, it is a good maternity dress. Not three. Not five. One really good one.

A jersey wrap dress in a neutral colour will see you through work meetings, dinner out, a baby shower, and everything in between. The wrap style adjusts as your bump grows, flatters basically every shape, and can be dressed up with jewellery or dressed down with trainers. It is the hardest-working item in your maternity wardrobe, and if you only buy one "nice" thing, make it this.

For everyday, a simple jersey midi dress in black or navy works as a blank canvas. Throw a denim jacket over it in spring, layer a knit over it in winter, and it takes about four seconds to put on when getting dressed feels like a full-body workout.

The Underwear You Will Actually Thank Yourself For

This is the section nobody warns you about, and arguably the one that makes the biggest difference to how comfortable you feel day to day.

Bras: Your regular bras will probably stop fitting around weeks 8 to 12, well before your bump is even visible. Do not immediately invest in expensive nursing bras. Buy two or three soft, non-wired maternity bras that give you room to grow. The ones with clip-down cups will work for nursing too, so you get double the use. Avoid underwired bras from the second trimester onwards as your ribcage expands.

Knickers: Under-bump bikini briefs in a size up from your usual are the most comfortable option for most people. Over-bump knickers exist and some women swear by them in the third trimester, but try the under-bump style first as it works for most. Buy in packs rather than individually, because pregnancy is hard enough without worrying about matching sets.

Shoes (The Bit Nobody Mentions)

Your feet can swell and even grow half a size during pregnancy, especially in the second and third trimesters. That pair of heels you planned to wear to the baby shower? They might not fit. More importantly, your centre of gravity shifts as your bump grows, making heels genuinely harder to walk in safely.

A pair of comfortable trainers and some flat ankle boots will cover most situations. If you are pregnant through summer, a pair of supportive sandals with a proper sole (not flip flops) is worth the investment. Slip-on shoes become increasingly brilliant as bending over to tie laces becomes a whole-body event.

The Money-Saving Cheat Sheet

Before you spend a penny on maternity clothes, try these:

• The bump band trick: A stretchy fabric tube worn over your unbuttoned jeans or trousers extends their life by weeks. They cost under a fiver and buy you time.
• Size up in normal shops: A t-shirt dress or oversized jumper from a regular shop in a size or two up often fits just as well as the maternity version, and costs half the price.
• Charity shops and marketplace groups: Maternity clothes are worn for a few months at most. Second-hand maternity wear is often in brilliant condition. Check local selling groups or charity shops near you.
• Your partner's wardrobe: Their shirts, hoodies, and joggers are fair game from now until delivery. Consider it a perk.
• Rent, do not buy: For special occasions like a wedding or christening, renting a maternity outfit for a fraction of the purchase price makes far more sense than buying something you will wear once.

What You Genuinely Do Not Need

A few things that maternity shops will try to sell you that are, frankly, a waste of money for most people:

• Maternity pyjamas: An oversized t-shirt and your partner's shorts work perfectly. Save the money for a nursing nightdress if you want one after baby arrives.
• Maternity coats: Unless you are pregnant through the coldest months and your existing coat genuinely will not zip, a regular coat in a size up or worn open over a scarf does the job.
• Maternity gym wear: Most activewear has enough stretch to accommodate a bump. If it does not, size up in your favourite brand rather than buying specialist pregnancy workout gear.
• Anything white: Pregnancy comes with surprise spills, unexpected nausea, and a general level of unpredictability. Save the white linen for the "after" chapter.

Your pregnancy wardrobe does not need to be complicated. A few well-chosen basics, a generous helping of what you already own, and a willingness to raid your partner's side of the wardrobe will see you through beautifully. The goal is not to look like a maternity catalogue. It is to feel comfortable, look like yourself, and not spend a fortune on clothes you will wear for a handful of months. You are growing an actual human. You can do that in joggers if you want to. 💛
