Old Navy
The halter top one-piece bathing suit from Old Navy is a great choice if you are petite. The plunging neck and ties draw the eye upward and focus in on your chest, instead of your legs or torso. The legs on this bathing suit are cut on the high side, which make your legs look longer. If you opt for a lighter color or one with a small pattern, it will make your torso look smaller and longer.
Shoshana
Shoshana is well known among petite women because the designer knows the perfect way to dress a petite body. The Shoshana bikini is the perfect example of this. It features a halter top, a small pattern and minimal decorations; all things you should look for in a swimsuit. The bikini flatters a smaller chest and also makes your legs look longer, while still creating the appearance of a long torso.
Jersey Lomellina
The Jersey Lomellina Ruched Halter Bikini from J Crew has a bikini top that gives the appearance of a fuller chest. Padding sewn into the top gives you an extra boost. The bikini bottoms are cut straight across the top, which help give the appearance of full curves. You'll also appreciate the cut of the legs, which makes your legs look longer.
Araks
The Araks at Creatures of Comfort is another best swimsuit for the petite woman. If you're looking for something more colorful, you'll love the bright orange-and-white flowered design on a bright purple background. The pattern is small enough that it does not overwhelm your petite frame, but large enough to make a statement. Ties on either side of the bikini bottoms let you adjust it for the perfect fit and take it from the beach to a race in no time flat.
