Love this set , super sexy but I should have sized up because I am more curvy

I'm in between sizes - After looking through the reviews I ended up getting a M, but wish I got a Large. There isn't really a waistband, and it doesnt go as high up as it does on the model. I like the colors and patterns, but it feels really thin and I'm not sure how well itll hold up. the top is better than the bottoms and has a silicone strip to help keep it up.
