Ashlee Simpson, Eres Bikini with White Piping ($358, brownsfashion.com)
Simpson has a slight tomboy vibe yet also loves her bright, girly accessories, and this suit perfectly melds her two styles. It's sporty enough for surfing and the marine blue color is very current.
Rachel Bilson, Anna & Boy Red Bikini with Keyhole ($198, brownsfashion.com)
This sweet bikini has delicate edging and a tiny pattern of white hearts, flowers, and spots that give the suit a feminine, slightly retro vibe that's perfectly in keeping with Bilson's style.
Nicole Richie, Missoni Zigzag Bikini ($259, brownsfashion.com)
The vibrant pattern and delicate hip ties of this Missoni suit would be an ideal choice for Richie. The popping red, purple, and turquoise zigzags compliment Richie's enviable, golden skin.
Sienna Miller, Topshop Panel Stripe One Piece ($56, topshop.com)
We've noticed numerous one piece suits with cutouts this season, and for some reason can completely picture Miller daring to wear this edgy style.
Kirsten Dunst, Top: Urban Outfitters Duo Twist Bandeau in black/white ($16, urbanoutfitters.com) Bottom: Old Navy Women's Bikini Bottoms in black ($16.50, oldnavy.com)
The graphic punch of this bandeau top, complimented by a classic, black bikini bottom, is the essence of the low-fuss/mod style of Kirsten Dunst.
