The Skinny Confidential Founder Lauryn Bosstick's Must Haves — Including Her Viral Ice Roller

Bosstick loves sporting Skims. According to her, the line is "completely designed to flatter the body." Her go-to is the Fits Everybody Crossover Bralette ($34) in nude or black. Designed for everyday wear and comfort, this bralette doesn't have underwire yet is still supportive and flattering. The bralette has a power-mesh lining that delivers coverage and support — she even wore it while breastfeeding. Plus, its V-neckline stood out to her the most "because it pushes your boobs together and gives them a lift, but it's not a 2001 push-up," she says.

Pro Tip: If you're wearing something strapless or an outfit that looks better without a bra, Bosstick recommends getting Nippies Nipple Covers ($27).
