This is the De Florista Dress from Mod Cloth. It's $63.99.
This the Motel Parrot Fit and Flare Dress from ASOS. It's on sale for $37.06 (originally $58.96).
Does anything really need to be said here? They are the EXACT SAME DRESS. They can call them different things and price them differently, but I'm not sure what I get from Mod Cloth for the extra $26.93 ($5.30 before it was on sale) except shame at over-paying for a dress that's beyond silly in the first place.
Do yourself a favor and SHOP AROUND, people. This is not rocket science, it's freaking highway robbery.
