Opt for this easy-to-throw-on Steve Madden Sleeveless Mini Dress ($49) for days when you don't want to spend much time getting dressed. The stretchy fit makes it ideal for all-day wear, while the entire look will convey an air of put-togetherness. You can wear it as a beach coverup, out to lunch, or even to a party (if you swap the sneakers or flats for kitten heels or strappy sandals).
