I am so tired of seeing women wearing clothing like this. If you want to wear low rise jeans, fine. But please, for the sake of everyone, wear a loose fitting shirt. This does NOT, in any way, shape or form, make you look thin. All it does is make you look bigger than you actually are. As a side note, even if you are wearing higher cut jeans, please wear a looser fitting shirt. As you can tell, even from these small photos, you can see what color skin each girl has through the shirt. That's not attractive.
Here are a few tips:
Buy a size larger shirt than you would normally buy if you want a "tight" shirt.
Wear a belly band.
Buy higher waisted bottoms. Notice I didn't say high waisted. You don't want "mom jeans".
Layer your clothing. Wear a camisole under or a cardigan or jacket over the top.
Look for prints and textures.
Wear dresses. Especially ones with an empire waist or front or side ruching.
Look for shirts with ruching.
