19 Slimming Coastal Dresses for Summer

1. Nautical Knit: Nothing says coastal chic quite like classic stripes. This ribbed knit midi gently hugs your curves with plenty of stretch, creating a sleek silhouette without feeling restrictive.

2. Sail Away: This striped halter mini looks as if it belongs at an oceanside resort. The tie-waist detail naturally defines your middle, giving the easy silhouette extra shape, while the stretchy fabric keeps it comfortable from brunch through beach walks. Add woven sandals and a straw tote to complete the look.

9. Draped to Impress: Ruching is one of fashion’s best-kept secrets for creating a streamlined silhouette. Soft draping along the sides gives this knit midi an elegant look that’s equally suited for weddings, dinner dates and special occasions. Cap sleeves and a modern funnel neckline complete the sophisticated design.
