Underwear for pregnancy and nursing: how to buy well

Updated 20 October 2026

Your size changes several times

Your bust changes more than once during pregnancy and nursing, so a bra bought at 20 weeks may not fit by week 34. If you buy ahead of the birth, choose a size with room and adjustable fastenings. Milk usually comes in on the third to fifth day, and the breasts grow noticeably.

On BlaBlaPrice you can describe your exact situation: what you need, which size, and what stage you are at. Underwear sellers reply with offers in the chat, and you compare without phone calls. It is free for the buyer.

What to put in your request

• what exactly — nursing bra, top, briefs, belt, set;
• size — underbust and cup, for example 34D;
• underwire — with or without; for nursing usually without;
• stage — week of pregnancy or “after birth”;
• material — cotton, micromodal, seamless knit;
• quantity — how many sets you need;
• colour, brand, budget.

Example: “I need 3 cotton nursing bras without underwire, size 34D, skin tone. A brand like Medela or similar, Pretoria, budget up to R 400.”

What to look for in a nursing bra

The cups should open with one hand, and the fastening should be a plastic or fabric-covered hook so it does not scratch. It is better to have no seams on the cup, as they chafe. Wider straps and three rows of hooks at the back let you adjust the size.

For sleep people choose a soft top with no fastenings. Briefs come with a high waist that supports the bump and low ones that sit under it. After a C-section people usually look for high ones that do not press on the scar, but it is best to check with your doctor what to wear.

During pregnancy and the first weeks of nursing it helps to have two or three bras, so one is in the wash, one is worn and the third is a spare. At night many sleep in a soft top with no fastenings. Breast pads are a separate purchase, and you can mention them in your request too.

How to compare offers

Ask for the fabric composition, the size chart and the exchange terms: hygiene items are often not returnable, so ask beforehand. Check that the contents are the same: one offer may be for a single bra, another for a set of three.

BlaBlaPrice shows the best-value offer first, with seller reviews next to it. Sellers can see where they stand among the others, so they may add a gift or lower the price for a set.
