Quick answer

Choose maternity underwear that grows with you: prioritize a high waist that sits under or over your bump without digging, fabric with real stretch (look for lace that stretches up to 150%), and a cut that matches your daily outfits. A maternity high waist brief is the most supportive starting point; if you prefer less coverage, a Brazilian or thong in a stretch lace works well for everyday.

Your underwear drawer is one of the first places you'll feel your pregnancy. A waistband that fit last month can turn uncomfortable overnight, and the wrong cut can create pressure exactly where you don't want it. This maternity underwear guide walks through what actually matters when you're choosing pregnancy underwear, from waist height to fabric stretch, so you can buy pieces that work now and later.

You don't need a completely separate wardrobe. Many maternity styles are built on the same stretch lace as everyday lingerie, just with a higher waist or a more generous panel. The goal is to find comfortable pregnancy underwear that supports your bump, stays put, and still feels like something you want to wear. Below are the decision rules we recommend, plus specific styles that meet them.

Start with waist height, not size

The biggest mistake is sizing up when the real issue is waist placement. A low-rise brief that sits under your bump can work in early pregnancy, but as your belly grows, a high waist that rests over the bump usually feels more secure and avoids rolling. Look for a waistband designed to stay put without squeezing. If you're between sizes, choose the size that fits your hips and let the stretch handle the rest.

Waist height also affects how the underwear looks under clothes. A high waist smooths the transition from bump to hip, while a lower cut disappears under low-rise jeans or a dress with a defined waist. There's no single right answer, but matching the waist to your most-worn outfits prevents the daily frustration of adjusting.

  • Measure your hips, not your pre-pregnancy waist, when choosing size.
  • If the waistband leaves marks, it's too tight, not too small.
  • High waist for support and smoothing; low rise for under low-cut clothing.

Fabric stretch matters more than fabric name

Cotton is breathable, but it doesn't stretch much on its own. Lace and modal blends with elastane give you the give you need as your body changes. Our signature stretch lace is engineered to stretch up to 150%, which means it adapts to your shape rather than fighting it. That stretch is what keeps a waistband comfortable for hours, not just minutes.

Look for a soft, flat finish at the edges. Scalloped lace edges can be pretty, but if the trim is stiff it can rub against a growing belly. A smooth, wide waistband distributes pressure better. If a product page doesn't list stretch percentage, treat that as a limitation and check the care label or return policy before committing.

  • Prioritize stretch percentage over fiber content alone.
  • Soft, flat edges reduce rubbing on sensitive skin.
  • No stretch spec? Assume limited give and size up cautiously.

Match the cut to your day, not just your trimester

A maternity thong can be surprisingly comfortable if the waistband sits in the right place and the fabric stretches. It's a good choice under leggings or fitted dresses where you want no visible lines. A Brazilian offers moderate coverage with a cheeky back, which many people find a good middle ground between a brief and a thong. For maximum support and coverage, a high waist brief is the most secure option.

You don't have to pick one. Many people keep two or three cuts on rotation: a high waist brief for support days, a Brazilian for everyday, and a thong for specific outfits. That small rotation covers almost every situation without overbuying.

  • Thong for no-show under fitted clothes.
  • Brazilian for a balance of coverage and lightness.
  • High waist brief for support and smoothing.

Plan for after birth, too

The same qualities that make maternity underwear comfortable during pregnancy, stretch, softness, and a high waist, also make it useful postpartum. A high waist brief can sit gently over a tender belly or a C-section scar without pressing. If you're building a maternity lingerie buying guide for yourself, choose at least one style that you'd be happy to wear in the weeks after delivery.

Look for easy care. Most stretch lace and modal blends hand wash well, but check the label. If you want low-effort care, choose pieces you can rinse and hang dry without reshaping. That practicality matters more when you're tired.

  • High waist styles double as postpartum support.
  • Choose easy-care fabrics if you won't hand wash often.
  • Buy two of the style that works, not five of a maybe.

Decision rules for buying maternity underwear

  • If you want maximum bump support: Choose a high waist brief with a wide, soft waistband that sits over the bump. Look for stretch lace that moves with you. Start with Maternity High Waist Brief - Coconut White.
  • If you want no visible panty lines: Choose a thong cut with a stretch lace waistband that stays flat. Silk or modal fronts reduce bulk. Silk Lace Thong - Polka is a strong pick.
  • If you want a balance of coverage and lightness: Choose a Brazilian cut with moderate coverage and a cheeky back. The stretch waistband should adapt without pressure. Brazilian - Coconut White or High Waist Brazilian - Umber.
  • If you're unsure about size: Measure your hips and compare to the size chart. If between sizes, size up only if the fabric has limited stretch; otherwise stay true to size. Check the stretch percentage before sizing up.

Maternity-friendly styles that meet the rules

  • Maternity High Waist Brief - Coconut White: Specially designed for expectant mothers, crafted in signature stretchable lace with scalloped edges and a high waist design that grows with your changing body. The high waist gives gentle support over the bump and can be worn postpartum; the stretch lace adapts instead of digging.
  • Brazilian - Coconut White: Moderate coverage with a signature stretch lace waistband that adapts to your shape for a barely-there feel. A good everyday option if you want less coverage than a brief but still want a waistband that moves with you.
  • Silk Lace Thong - Polka: Lustrous silk front with signature stretch lace waistband that stretches up to 150% for a personalized fit. Useful under fitted outfits when you want no visible lines; the stretch waistband keeps it comfortable as your shape changes.
  • High Waist Brazilian - Umber: Blends high waist and Brazilian cuts; high-waisted design supports in all the right places for a smooth silhouette, while the cheeky Brazilian back keeps things light. Signature stretch lace stretches up to 150%. A hybrid for those who want front support and a lighter back, with the same adaptive stretch.

Who these styles are for

Best for

  • Anyone in the second or third trimester who wants gentle bump support.
  • Postpartum recovery when a high waist feels more comfortable.
  • Everyday wear under dresses, leggings, or work clothes.

Not for

  • Those who prefer very low-rise underwear with no waist coverage.
  • Anyone looking for shapewear-level compression.
  • People who want a cotton-only fabric with no stretch.

The right maternity underwear comes down to three things: a waist height that matches your bump and your outfits, fabric that stretches with you, and a cut you'll actually reach for. Start with one high waist brief for support and one lighter style for no-show days, then adjust as your body changes.
