You need to be careful with sizing on these leggings - the first pair I bought were in my normal size, and don't get me wrong they were comfy, perfect for gym and casual wear, however I do have a bigger bum and hips and they were see through on the bum. Despite this I love them and I just wear longer tops. I then bought a second pair and risked getting a size up to prevent the see through issue. I was worried they would be too big on my waist but they cake and fit well (just a bit long then) and they weren't see through anymore! I just folded the leggings up at the ankle and then they were perfect. I will likely buy more pairs of these - very reliable!
