There is a big difference between the front and back of Barbie Library. The front waistband of Barbie pants is slightly shorter, while the back waistband of Barbie Cool Store is slightly higher than the front waistband, which has a certain curvature. The position of Barbie Cool Store's rear butt is larger than the front waistband, so we can easily distinguish it. Moreover, Barbie's library has a lot of buttocks, and there will be a pot-shaped material that can hold up the buttocks.
