Maternity Underwear After Birth: What to Wear First

A step-by-step guide to choosing postpartum underwear, from the first 24 hours through the weeks after delivery, with fit checks and common mistakes to avoid.

Quick answer

For the first days after birth, choose underwear that sits below any incision or sore area and holds a maternity pad without pressure. As bleeding settles, switch to a supportive high waist style that stretches with you. Start with one low waist maternity option and one high waist option, then decide which feels better on your body.

Match the rise to your first week, not to your pre-pregnancy size

Your waistline in the first week after delivery is not a reliable size guide. Swelling, a healing incision, and pad placement all change where a waistband should sit. Instead of guessing a number, decide where you want the band to rest: below the bump line if you had a cesarean or have tenderness low on the abdomen, or across the natural waist if you want gentle support and a smooth line under clothes. A low waist design such as the Maternity Low waist Hipster - Coconut White is built to sit below the bump, while a super high-waisted style keeps pressure higher up and away from a low incision. Try both rises in your first week rather than committing to one.

Check stretch and recovery before you size up

Stretch matters more than the number on the label in the weeks after birth. A fabric that stretches up to 150% follows your body as swelling goes down, so the same pair can feel supportive on day two and still comfortable on day twelve. That is the opposite of stiff cotton that holds its shape and starts digging in. If a pair leaves red marks that fade within an hour, it is snug but workable. If marks last longer or you feel throbbing, that is a fit problem, not a size problem. Change the rise or the style before you change the size, because a larger size in the wrong rise will still sit on the wrong spot.

Plan the switch from pad-friendly to shape-friendly

The underwear that works on day one is rarely the underwear you want by week three. Early on, you need a style that holds a maternity pad flat and lets you check it without a struggle. Later, when bleeding is light and you are moving more, a supportive high waist cut feels better under clothes and gives gentle shaping. The High Waist Brazilian - Terra blends a high waist with a cheeky back, so it supports the abdomen while staying light where you sit. The High Waist Thong - Umber removes back coverage entirely, which some people find cooler and less bulky once pads are no longer part of the routine. Switch when your pad stays put without extra help, not on a fixed calendar date.

Wash and rotate so you are never caught short

You will change underwear more often than usual in the first two weeks, so buy in a small rotation rather than one perfect pair. Three to five pairs lets you wash frequently without running out. Rinse promptly, wash with like colors, and skip fabric softener, which coats stretch fibers and reduces the give you are relying on. Lace holds up well when it is not tumbled dry on high heat. If a pair starts to feel loose rather than supportive, that is your signal to move to a smaller size or a different rise, not to keep stretching the same one.

Your first two weeks, step by step

  1. Step 1: Pick the rise before the size: Decide where the waistband should sit based on where you are sore, then choose low waist or high waist. Do not start by sizing up. Checkpoint: if the band crosses a tender spot, change the rise first.
  2. Step 2: Test stretch, not stiffness: Choose a fabric that stretches with you, such as lace that stretches up to 150%, so the fit follows swelling as it goes down. Checkpoint: red marks that fade within an hour are fine; lasting marks are not.
  3. Step 3: Keep one pad-friendly pair on hand: In the first days, wear a style that holds a maternity pad flat and sits below any incision. Keep it in the rotation even after you switch. Checkpoint: if the pad shifts when you move, the rise or fit is wrong.
  4. Step 4: Switch to support when bleeding settles: Move to a high waist style for gentle shaping once pads are no longer needed, choosing Brazilian for a lighter back or thong for none. Checkpoint: switch based on how you feel, not a set date.
  5. Step 5: Rotate and wash gently: Keep three to five pairs in rotation, rinse promptly, and skip fabric softener so the stretch stays intact. Next step: replace any pair that feels loose rather than supportive.
