We found this flattering heather grey cap sleeve dress, courtesy of Alice & Olivia. Stretchy without being too clingy, with a color that provides lots of options for whatever you choose to pair it with. Pick a bright color for a pop, like yellow, shown here, or one of the darker jewel tones when it's cooler and you have to wear tights.
The metal zipper detail on the back adds a little edge.
Another easy office timesaver...and you don't have to go to the gym to rock it!
