The product overall seems pretty good, and definitely can be used by women of different sizes but one size can't really for all, so I do recommend to check measures in the product page.
If you plan to buy this as a gift, you need to be aware that it comes with NO instructions at all, even if on the Amazon product page it has a picture showing how to wear each individual wrap, so you may want to print that and put it with the product , or else the person who you will gift it to may have no idea how to use them!
So definitely the package could use a bit of improvement and include the instructions! Beside that it seems a very well done product, not really likely to fall a part after few weeks of using it. It well covers all the area is supposed to and you can decide to just wear one, two or all three the wrap for maximum coverage and results. I can't really say much about results yet as I didn't use it for very long, but usually such products are recommended after pregnancy so I suppose it will help!
