Has anyone ever ordered bottoms from this seller, especially leggings and skinny jeans? They don't have free returns so I would love to hear about fit and quality!

The leggings are one size fits all which makes me nervous. I'm wondering if they're thick and not see-through, and about the quality of the over-the-belly band. Same with the skinny jeans...I've tried some jeans (ahem, H&M) where the belly band is not stretchy enough at all and the jeans hardly stay up.

Any experience?
