Maxi dresses make me feel like I'm going to prom again...is that good or bad? Probably bad since I expect a corsage every time I wear one.
Equinox Stripe Maxi Dress, $158.00 at Anthropologie
And Gap saves the day with a maxi under $50:
Striped Jersey Maxi Dress, $49.99 (Reg. $69.95) at Gap. (Hint: Gap stores usually have sale items for cheaper than the prices online, so this might be even cheaper in store.)
Admittedly, I like the more expensive version more...
