Kids’ Swimwear Mystery Box

Affordable kids' swimwear can be hard to find—unless you stick with us, of course. Sydney So Sweet is back at it again with another can't-miss mystery box! This one is devoted to toddler girl swimsuits. Gear up for the summer or make sure that your little girl is ready for your next family vacation in a warm, sunny climate. She'll be over the moon when she receives a Mystery Box in the mail, and you'll be thrilled that you just got her three new swimsuits for the price of one.

Unboxing the Mystery

What will the Swim Mystery Box hold? Each box contains the latest and greatest trends in kids' swimwear. Our in-house experts always have an eye out for the most adorable swimsuits for babies, toddlers, and little girls.

Your little girl's box may contain a cute bikini or toddler girl swimsuits in the tankini style. You don't know if she'll score a one-piece, a two-piece, or one of each! Since there are three suits in each box, there's plenty of room for variety.

When you're ready to order the Swim Mystery Box, all you have to do is select the right size for your mini mermaid. Leave the rest up to us! Because our boxes are ready to ship with items curated by the shippers from our Swim tab, we'll send them out as quickly as possible. Guess what else? The shipping is on us, too!

Get all the kids' swimwear that your little girl will need this summer. While you're at it, make sure you pick up some shorts, tee shirts, and other warm-weather outfits, too.
