It was hard initially to fasten (I started at the bottom where it was wider/tighter and worked my way up) but it got easier as I went.
I was not a fan of the g-string that came attached, just seemed a little cheap, but I mainly wanted the corset so it was not a big deal.
I love the lace-up on the back that you can use to tighten it as need be. It is super cute too! I think I was in between a medium/large size, because I did not really get an hourglass shape with it on and the corset was noticeable under my shirt. I had it pretty tight, but I'm assuming I could tighten it even more to achieve more of an hourglass shape, but I didn't want to make myself too uncomfortable right away. I also have narrow hips, which likely also affected how I looked after.
I'm still pleased with this product because not only is it cute, but it does suck everything in and molds your body to the corset. The quality of the corset was nice and I liked the simple design on it. Overall, I am pleased though there are a few things I just like rather than love.
