Looks good on!
Color: OFF BLACK 1B
This is a really pretty wig and looks good on. It eventually starts to tangle a little, depending on how often you wear it. Don't sleep in it. It's very soft.

DOESN'T LAST
Color: DRF ESPRESSO BROWN
It's pretty, but very thin, and hard to manage, doesn't last long either. Not worth the purchase.
