Learn when to size up in the Grow with Me Maternity & Postpartum Brief. Practical decision rules for pregnancy and postpartum fit, plus honest trade-offs.

Quick answer

Size up in the Grow with Me Maternity & Postpartum Brief when the waistband leaves deep marks, the fabric feels tight across your bump, or you are in the final weeks of pregnancy and want room for postpartum swelling. Otherwise, start with your pre-pregnancy size and let the stretch do the work.

Why the Grow with Me Brief stretches—and when stretch isn’t enough

The Grow with Me Maternity & Postpartum Brief is designed to adapt through pregnancy and postpartum, so it accommodates a changing body without feeling restrictive. That stretch is the reason many shoppers can keep their usual size. But stretch has limits: if the brief feels compressive rather than gently supportive, sizing up gives you more room without losing coverage.

A common mistake is sizing up too early. If the brief fits well in early pregnancy, stay put. The fabric is meant to grow with you, and an oversized pair can slide down or bunch. Use the fit checks below to decide when a larger size is actually needed.

The trade-off: more room vs. more coverage

Sizing up usually means a little more room in the waist and hip, which can be a relief in late pregnancy or the first weeks postpartum. The trade-off is that a larger size may feel looser once swelling goes down, and full-coverage styles can shift if they’re too big. If you’re between sizes, consider your stage: late pregnancy and immediate postpartum often favor the larger size, while earlier pregnancy may not.

Postpartum sizing: plan for swelling, not just your bump

After birth, your body changes quickly. You may have swelling, a tender incision, or simply want less pressure on your abdomen. The Grow with Me Brief’s high-rise, full-coverage design is meant to sit gently over the belly, but if you feel constriction, size up. Keep in mind that postpartum underwear sizing tips often recommend prioritizing comfort over your pre-pregnancy number—especially in the first two weeks.

Decision rules: when to size up in the Grow with Me Brief

  • Waistband leaves marks or feels tight: If the waistband leaves red marks or you feel constant pressure, go up one size. The brief should feel gently supportive, not compressive. Check for marks after 30 minutes of wear.
  • You’re in the third trimester or first weeks postpartum: Your body is still changing rapidly. If you’re buying ahead for postpartum, choose the larger size if you’re between sizes—swelling and recovery often need extra room. Consider buying two sizes if your budget allows.
  • The brief slides down or bunches: If your current size shifts or bunches, do not size up—that usually means the fit is too loose. Stick with your size or try a different style. Re-check your hip measurement before ordering.
  • You’re between sizes on the size chart: For pregnancy, size down if you prefer a snug fit; size up if you want room to grow. For postpartum, size up for comfort. Use your current hip measurement, not your pre-pregnancy size.
