Classy
Size: 9, Color: Black/Black
I like how they give a little elevation but are still casual enough to wear with shorts. I recommend buyers break them in a bit before by wearing them for short periods of time/not a lot of walking prior to wearing all day.

Beautiful purse!
Size: One Size, Color: Vanilla
Wow! I love this purse! It is beautifully made and very good quality. It's the perfect size for holding everything I need without being bulky or too tightly packed. The shoulder strap is the perfect length and does not dig whatsoever. I love anything Lucky Brand and this did not disappoint!
