The Corset is not bulky and is flush with your skin; however because of the closure location, it may be slightly visible underneath certain fabrics or if you are wearing a fitted top. Keep in mind though that your comfort and healing process is the most important factor!
If you prefer a style with no front closures, take a look at these other options:
Girdle with Size Zipper
Girdle with Front Zipper
Girdle Pull-Up
