You’ve been known to spend a good deal of time on your knees (prodigious yoga practice, of course). So thank your lucky knobs for local designer Nikki Poulos’s collection of colorful maxi dresses. Hide those shameful joints under a sea of silky jersey cotton. The line includes halter-top and strapless frocks in bold patterns and bright solids. A flowy striped number in a daring palette (pink, purple, cream, and brown) will turn you into one well-ventilated vixen. Or snag one of her custom-made knit dresses — either floor length or a fitted strapless mini (for nights when you’re not afraid to show some skin). Ecofriendly bonus: Poulos makes her knits using cashmere gathered from resale shops. Environmentally sound and stylish to boot? It’s enough to make you weak in the knees. Available at Rumeur, 170 Northeast 96th Street, Miami Shores (305-754-9800); Emporium, 4710 South le Jeune Road, Coral Gables (786-268-0689). For custom orders, go to nikkipoulos.com.
