ON maxi dress shrinkage?

[monsterellachz]

I bought a navy maxi dress at Old Navy at the end of last month. I'm 5'6" and it was to the ground on me, after I washed it it's to my ankles (shrunk 3-4"). I washed cold and hung to dry. It says wash by hand, dry flat... but that shouldn't have made a 3" difference!! I used viggle points for the gift card, but that is still super lame. Would you return it (or do you think they'll take it back)? I was just there b/c the pj set I bought at the same time had 2 different sizes... It'll be another couple weeks before I can get back.

I would take it back. You only wore it once and it shrunk. Not cool at all
