Tips for Selecting Plus Size Swimwear
Merchant selections of maternity swimwear in plus sizes is not very extensive. Many maternity stores don't stock plus size suits or they may not carry swimwear at all. However, you should be able to find enough suits to give you a few styles to choose from so you have a swimsuit when you need to start wearing maternity clothes.
Flattering Designs
You'll find classic designs as well as fashionable, trendy ones in styles like skirted suits, basic tanks, and tankinis. Some skirted suits may feature generously cut skirts which fall from above the belly and offer a bit of sexy swing. You may also come across "swim skirts," which you use for coverage over more revealing bottoms. Tanks offer simplicity: no frills, no fuss, and they'll stay in place if you want to swim. Tankinis are two-piece suits with tank tops instead of bikini bras. Depending on the fit, your belly may peep out below the top.

Size Considerations
Most shops that sell plus size maternity swimwear will tell you to choose the same size you normally wear. The suits are specially designed to allow room for your growing belly. However, if you've gained or lost weight with the pregnancy, you might find your size has changed. If you order online, check the return policy before you place your order.
An Important Accessory
In addition to swimwear, you may want a cover-up for cool evenings by the ocean or casual dinners poolside, and a t-shirt or sarong might not look attractive over your pregnant belly. Only a few stores offer cover-ups sized to pair with extended size maternity swimwear; therefore, you may need to get creative by using a cotton or linen button-down shirt from a plus size maternity active-wear line. Finally, try topping your swimwear with a flowing caftan or jersey knit dress made for plus size pregnant moms so you can stay comfy and still look polished and poised.
Combine Function With Fun
With all the discomfort associated with pregnancy, why add the stress of worrying how you might look in swimwear or fearing you may have to sacrifice an activity you enjoy like swimming because you can't find the perfect suit? With so many fashionable, functional styles available from merchants who specialize in providing extended sizes swimwear, you'll be able to enjoy swimming, lounging poolside, or soaking up some sun throughout your pregnancy in your new swimwear.
