Whether you're gearing up for an epic summer vacation, or simply getting antsy for sun-filled days in Dolores Park, a great swimsuit is a must. This year, the Spring/Summer and Resort/Cruise 2012 collections showcased several key trends -- color-blocking, cool cut-outs, provocative straps, lavish prints, scuba, belts, high-waisted bottoms -- to keep in mind while selecting the perfect suit.

While swimwear design is more varied than ever, for most of us it all boils down to two main concerns -- fit and flattery. For a retro-fresh and flattering-to-boot bikini, try Norma Kamali's high-waisted bottoms (#2). If you're looking to create some curves, slip into Zimmerman's sleek, black mailot (#7), with a belt and clever cut-outs that define and accentuate shape.
