It's my favorite leggings now! It's very stretchy and therefore it goes well around my belly, I'm now 7 months pregnant and still can wear them. :) It's also great for a low-intensity workout, I do my yoga in these comfies. Although it's very stretchy it not losing its fit. But if you would like it to be tighter, I would recommend choosing a smaller size, like if you regularly wear M, S should also fit you.
I recommend this product
