When looking for a slinky cocktail dress this summer, the criteria to consider are fit, comfort, and whether it properly shows off your glowing tan. Not to mention whether it keeps your starved piggy bank intact. This simple sateen tank dress by ADAM fits the bill, with a plunging sweetheart neckline and a sexy crisscrossed back — and it comes in both black and white. Plus, with the recent markdown to $89 (originally $295), you'll still be able to afford mojitos on your night out.
