From the get-go, be sure that you’re buying the correct size bathing suit if you want to avoid a sagging bottom. This may seem like common sense, but the elastic fabric of swimsuits continuously stretches over time. One common mistake that causes people to buy ill-fitting bottoms in the first place is getting one-size bikini sets (per Cosmopolitan). While these one-size sets may seem like a convenient deal, consider your body type before you commit to your purchase. The size that fits best on top may not be the same for your bottoms. Avoid buying bikini sets that don’t allow you to mix and match the sizes that work best for your body.
Once you have your ideal swimsuit, it’s important to take care of it accordingly. Always wash your bikini in cold water. Though it might seem like a hassle, it’s best to wash your swimsuits by hand in lieu of throwing them in the washing machine with the rest of your laundry. The harsh tumbles a swimsuit takes on in the wash can make the fabric wear out sooner. And yes, you do need to wash your swimsuit. Saltwater and chlorine should be rinsed out soon after you’ve gone swimming, according to Vivek Agarwal, who is the founder of swimwear brand Ookiah (per Glamour). If you do put your bathing suit in the washing machine, be sure to use cold water and refrain from adding fabric softener. However, you should never put your bathing suit in the dryer.
