Maternity Swimwear: What Size to Pick?

Maternity Swimwear: Your Pregnancy Sizing Questions Answered

Navigating maternity wear can be tricky, and swimwear is no exception. We know you want to feel comfortable and confident whether you're lounging by the pool or enjoying a beach day during your pregnancy. Let's dive into the specifics of our Maternity Swimwear One Piece and address common sizing concerns.

"I'm normally a size 12 in regular swimwear but I've heard maternity sizing is different. I'm currently 28 weeks pregnant - should I size up or stay the same?"

This is a fantastic question, and the short answer is: stay with your pre-pregnancy size. Our Maternity Swimwear One Piece is intentionally designed with your changing body in mind. For a customer at 28 weeks pregnant, we recommend sticking to your usual size 12. The key is the specialized belly panel, which offers significant stretch and accommodation for your growing bump throughout your pregnancy.

"My bust has gone up about 2 cup sizes. Will the swimwear accommodate that or do I need to go up for the bust?"

We understand that bust size changes are a significant part of pregnancy. Our Maternity Swimwear One Piece features a generously designed bust area to cater to these common changes. For an increase of 2 cup sizes, your usual size 12 should still provide an excellent fit. The design is built to comfortably accommodate up to a 3 cup increase, offering ample room without compromising on support. Additionally, the adjustable straps are a crucial feature, allowing you to fine-tune the fit around your bust and shoulders for personalized comfort.

"And what about after baby arrives - will it still fit for postpartum swimming?"

Yes, absolutely! One of the wonderful benefits of our Maternity Swimwear One Piece is its versatility. Many mothers find that it continues to be a comfortable and supportive option for swimming during the postpartum period. The swimwear provides excellent compression and support, which can be beneficial for recovery. For most, the pre-pregnancy size 12 will continue to fit well as your body naturally adjusts and returns to its pre-pregnancy shape. This means you get more wear and value out of your swimsuit.

How It Fits

The Maternity Swimwear One Piece offers a flattering and functional fit designed to adapt to your body's transformations. It provides gentle compression that feels secure without being restrictive. The fabric has substantial stretch, particularly in the crucial belly panel, ensuring it comfortably hugs your bump as it grows. The adjustable straps allow for customization, ensuring the top stays put and provides adequate support for your bust. The overall silhouette is designed to skim your body gracefully, offering both comfort and a chic look throughout pregnancy and beyond.

Size Recommendations

General Guideline: For this Maternity Swimwear One Piece, we recommend starting with your regular, pre-pregnancy size. The design inherently accounts for common pregnancy changes.

Body Type Considerations:

• Growing Bump: The ample stretch in the belly panel means you likely won't need to size up solely for your midsection. It's designed to expand with you.
• Bust Changes: If you've experienced significant bust growth (up to 3 cup sizes), your regular size should still be sufficient due to the design and adjustable straps.
• Postpartum: The supportive fabric and adjustable fit make it a viable option for postpartum wear as your body recovers.

Common Fit Issues (and how we've addressed them)

• Tightness Around the Belly: This is the most common concern, and our Maternity Swimwear One Piece specifically counters this with an extra-stretchy, expandable belly panel. You should not feel restricted or uncomfortable around your growing bump.
• Lack of Bust Support: With adjustable straps and a design accommodating up to a 3-cup increase, adequate bust support is prioritized. Ensure the straps are tightened appropriately for your comfort.
• Gapping in the Bust Area: While designed for expansion, very dramatic bust changes might require slight strap adjustment. However, significant gapping is not typical for this style.

Between Sizes: What to Do?

If you typically find yourself hovering between two sizes in regular swimwear, for our Maternity Swimwear One Piece, we generally advise sticking to the smaller of your two usual sizes. Here's why:

1. Fabric Stretch: The swimwear boasts significant stretch throughout, especially in the critical areas like the belly and bust.
2. Designed for Change: It's made to accommodate increases, meaning starting with your closest regular size is usually best. Sizing up might lead to a suit that feels too loose in areas that aren't changing as dramatically, or that becomes baggy once your body starts to adjust postpartum.

If you are unsure, prioritize your usual size, and focus on the bust measurement as the primary variable. The adjustable straps offer a great way to customize the fit, even if you're right on the cusp.
