Disappointing
Size: 7, Color: White Leather, Size: 7, Color: White Leather
Beware: the heel height is not 3 inches! The shoes are comfortable, but the material looks and feels like plastic! I would choose another color.

It’s a beautiful bag limited to the size inside but for an elegant dinner engagement it is well worth the money
