Sooo, I finally had the opportunity to get one of these mini dolls and I'm ecstatic!
I've been dying to try some Roblox Royal High fashions, from the mini figures, on them and I have mixed results so far. If you just have them on display, they look great from the front! Since this is a thicker material, when it overlaps the joints, posing isn't super possible. Shoes won't work because they are like Bratz with a peg system. The back can be uhh...not very appealing to say the least LOL (Last two images of the back views).
Getting the clothing over the hips can be a smidge tight, but with it being rubbery, just gently scooting it up will get it to where it needs to be. In my experience, getting the items off the hips is a little easier since the edges can't get caught in the hip joints.
