Nice shoe. Looks more expensive than it is.
Size: 8, Color: Classic Dark Brown
Bought for a formal party and had no brown shoes. Inexpensive and looks worth more than it is. Fairly comfortable had no issues with it. Not that much grip on bottom though. But still a good shoe for ~40$

Jacket is extremely large
Size: Medium, Color: Classic Light Wash
Runs big, the arms look and feel like they are from a MALE PATTERN AND STICK OUT LIKE IM A MALE BODYBUILDER. Back is very large , too much fabric… the entire jacket. It looked ridiculous on a woman.
