Maternity Underwear and Bras: What to Wear During Pregnancy

During pregnancy, choose soft wireless bras with a stretchy band and either under-bump or over-bump underwear in breathable cotton. Buy in stages rather than all at once, because your size keeps changing — and don't invest in a precisely fitted bra until later on. Here is what works, and when.

What changes during pregnancy?

Your ribcage widens, your bust changes size more than once, and your waistline stops being a useful reference point. All three happen at different rates.

The ribcage change is the one people don't expect — it means band size often goes up even when cup size hasn't settled. That's why a bra bought in the first trimester frequently doesn't fit by the third.

What bra should you wear while pregnant?

A soft, wireless bra with a stretchy band, wide straps and a generous hook range. Flexibility matters more than shape.

• No underwire, which can press uncomfortably as your shape changes
• A stretchy band that accommodates a widening ribcage
• Wide straps, because a heavier bust pulls on the shoulders
• Several hooks, so one bra lasts across more of the change

Our Blossom Beauty ultra-light wireless bra is soft and wireless with a stretchy band, and the Opulent Allure front-clasp bra is easy to fasten when reaching behind your back is awkward. Neither is a dedicated maternity or nursing bra with drop-cups — for feeding specifically, see nursing and breastfeeding bras.

Under-bump or over-bump underwear?

Both work — it comes down to what feels right as the bump grows. Most people end up using both at different stages.

• Under-bump: sits low beneath the bump, with no pressure across it. Usually more comfortable later on and in the heat
• Over-bump: a soft high panel that covers the bump, warmer and more supportive, and some prefer the held-in feeling

Either way, breathable cotton or a cotton gusset matters more than usual — see cotton vs synthetic underwear.

Can you just wear your normal underwear?

Often yes, especially early on, if you choose the right cut. Dedicated maternity underwear isn't compulsory.

Low-rise and high-rise styles both work: low-rise sits under the bump naturally, while a soft high-rise in a stretchy fabric can sit over it. What to avoid is anything with a firm elastic waistband that digs in. Our full-coverage Comfy Classic boyshorts have a wide, soft waistband, and the seamless Smooth Operator 7-pack is light and stretchy.

When should you buy?

In stages — and resist buying a full set early. This is the practical money point.

Buy a couple of soft, stretchy pieces when your current ones stop being comfortable, then reassess. Around the third trimester things settle enough to buy a little more confidently. Leave a proper fitted bra until after the baby arrives and your size stabilises, which can take months.

What about comfort at home?

Soft, loose loungewear with an elasticated or no waistband. You'll live in it, especially late on.

Relaxed sets like Ethereal Breeze or the three-piece Chic Serenity work well. See also postpartum bras and loungewear for what comes next.

Frequently asked questions

Can you wear an underwire bra when pregnant?

Many people find it uncomfortable as the ribcage and bust change, so a soft wireless bra is the usual recommendation. If you have any specific concern, ask your doctor or midwife.

Do you need special maternity underwear?

Not necessarily. Soft, stretchy, breathable underwear in a cut that doesn't dig in works for many people. Dedicated under-bump or over-bump styles are a comfort upgrade rather than a requirement.

When should I buy maternity bras?

Buy soft, stretchy ones as you need them rather than all at once, since your size changes repeatedly. Leave a precisely fitted bra until your size settles after the birth.

Does Erblis deliver in Karachi?

Yes, with free delivery across Karachi, Cash on Delivery, discreet packaging, and a free tote bag with every order.
