Tips for Choosing Lingerie Size During Pregnancy

So, you're expecting—congrats! 🎉 But let's talk about something every mama-to-be faces: your body is changing faster than a TikTok trend. One of the trickiest parts? Finding lingerie that actually fits and feels good. Say goodbye to digging underwires and hello to comfort with these smart, stylish tips on choosing the right lingerie size during pregnancy.

Why Regular Bras & Panties Just Won’t Cut It

Your breasts can swell by up to 1–2 cup sizes in the first trimester alone. Add in softer tissue, sensitive skin, and a growing belly, and it’s clear: your pre-pregnancy lingerie isn’t going to work. The average woman gains between 25–35 lbs during pregnancy, and much of that weight impacts your torso and hips—key zones for lingerie fit.

When (and How) to Measure for New Lingerie

Forget one-and-done sizing. Experts recommend measuring every 4–6 weeks throughout pregnancy. Here’s how:

• Band size: Measure snugly under your bust. If it’s an odd number, round up.
• Bust size: Measure around the fullest part of your chest, keeping the tape parallel to the floor.
• Cup size: Subtract band from bust measurement. Each inch equals one cup size (e.g., 4 inches = D).

Key Features to Look For

• Adjustable straps: Your shoulders may carry more weight, so customizable support is key.
• Drop cups: Super helpful for nursing later—many maternity bras include this feature.
• Stretchy, breathable fabric: Think organic cotton, modal, or moisture-wicking blends. Avoid underwire unless it’s fully encapsulated and flexible.
• Side slings: Provide extra lift and separation as your bust expands.

Don’t Forget the Bottoms!

Maternity panties aren’t just about size—they’re about function. Look for:

• Low-rise, full-coverage styles that sit below your bump.
• Soft lace or bamboo blends that won’t dig into swollen tissues.
• Disposable liners built-in? A game-changer for light discharge or leaks.

Pro Tip: Invest in Multipurpose Pieces

A great sleep bra can double as a nursing bra. Wireless, seamless styles work perfectly under tight-fitting maternity tops. Brands like Bravado, Kindred Bravely, and Pumpkin Maternity offer pieces designed to grow with you—and last beyond delivery.

The Takeaway

Pregnancy lingerie isn’t about sacrificing style for comfort—it’s about finding the sweet spot where both meet. Measure often, prioritize stretch and support, and don’t be afraid to upgrade as your body evolves. After all, feeling confident and cozy is one of the best gifts you can give yourself during this beautiful journey.
