Now that we’ve tackled swimsuits, my thoughts turn to that other essential pool/beach garment—the cover-up. What once used to be just a simple pareo or an oversized T-shirt has developed into a chic genre of its own, available in an array of shapes, fabrics and lengths.

Based on my many observations lounging poolside, simplicity is generally sexier and most flattering. Cover-ups in solid colors and natural fabrics with a little reveal in a short length are the way to go. The Ava by Miguelina is sure to be a standout on the coast of Lake Michigan or in St. Tropez and can take you from a nice Champagne brunch to the boardwalk.

Just don’t forget the sunblock!
