Your body changes fast during pregnancy, and your workout wardrobe needs to keep up. What fits and feels supportive in week 10 can feel restrictive by week 30, and what you actually need postpartum is different again. Here's what changes at each stage, and what to reach for.
First Trimester: Barely-There Changes, Comfort First
Most people don't need maternity-specific sizing yet, but early pregnancy brings bloating, tenderness, and nausea that make tight waistbands and underwire bras miserable. This is the stage to switch to soft, wide waistbands and wireless support, even if you're not showing.

By weeks 14-27 most people are showing and the belly is growing fast. This is when a proper belly panel earns its keep: it should sit under or over the bump without digging in, and stretch with you instead of rolling down. Over-the-belly styles with side pockets are the easiest switch to make since they layer under the bump comfortably even as it grows.

In the final stretch, comfort wins over everything. Look for a wide, non-rolling belly band, breathable seamless fabric that won't overheat, and stretch that goes past what you think you'll need. Many people also start sizing up in leggings during this stage rather than switching styles entirely.
Postpartum: Recovery Support, Not Pregnancy Clothes
After birth, your needs flip again. A high-power belly band supports your core while your abdominal muscles recover, and nursing-friendly tops and bras with easy front access become the daily uniform, not just gym wear.
Postpartum Belly Band with Zipper
High-power compression to support your core as it recovers.

Frequently Asked Questions
When should I switch to maternity leggings?
Most people switch somewhere between weeks 12 and 20, once regular waistbands start feeling tight or uncomfortable. There's no fixed rule, go by comfort rather than a calendar date.
Can I keep wearing the same leggings after birth?
All-stage and seamless styles with a full belly panel are usually comfortable through early postpartum since the panel can double as light compression. Many people size back down over the following months as swelling goes down.
Do I need a belly band if I'm not having a C-section?
A belly band isn't only for C-section recovery. It offers general core support while your abdominal muscles and ligaments tighten back up after any delivery, and many people find it helpful for posture and lower back support too.
