The Service: Upon request, you'll receive a box with five items tailored to your size, shape, taste, lifestyle and budget, each accompanied by a few "style cards" enumerating the different ways it can be worn. Try everything on at home, keep what you like and send the rest back in a prepaid envelope—easy!
The Cost: While every shipment has a $20 "styling fee" attached, you can put it toward whatever you buy; if you don't keep anything, however, it's a sunk cost. As for the actual clothes, the average price of each piece is $65.
The Commitment: Updating your profile is essential to getting the best options possible. That means logging any changes in size, and giving lots of feedback on each package you receive.
