Finding the Right Support
To prevent discomfort, look for support in three key areas—your bust, hips, and tummy.
For proper breast support, Matthias advises soft, molded-cup bra styles. Women with large breasts may want to consider an underwire bra. But pay attention to the fit. Dr. Salsbury points out that some underwire styles may be too tight for already sensitive, sore breasts.
Atkin adds another option—shelf bras. Shelf bras offer less bust definition but work well for serious swimmers. The style of support you choose depends on the amount of support you need. Remember that your breasts will most likely increase, so don’t choose a style early in your pregnancy that’s already tight.
If you’re concerned about bust support, also consider the type of straps on the suit. Flatter-chested women may be able to pull off halter styles, but for more serious support, Atkin advises tanks or a suit with wide straps (she adds that an empire waist style will add support, too). Whether you choose wide or thin, look for adjustable straps so you can increase the length as needed.
Your hips will also expand during your pregnancy. Test your suit for flexibility. Atkin suggests materials with the most amount of stretch, such as the 20-percent Lycra offered in the Prego line. Beyond fabric, some suits offer adjustable side ties, too.
When it comes to showing off your growing belly, only you can decide what works. The most important point, in terms of support and your tummy, is that your suit can grow comfortably with your pregnancy and the fabric is never tight across your bump.
