Forever 21 Pleated Chiffon Dress ($27.80)

Inexpensive, classic, lady-like dresses can be hard to find, which is why I was especially excited to come across this Pleated Chiffon Dress at Forever 21. I like the high neck and wide waistband in lace, but it's the pleated chiffon that makes this a classic. You could wear this at any age.
