I am very well aware that this corset is an under boob style, so youd think your own cup size wouldnt matter, right?  Wrong. It fits me fine everywhere except the underboob. I or my husband can tighten it all day long until I cant breathe, and there is still just way too much material up top.  I vary between a 36C/34D, size 8 waist/hips. It looks like youd need to be a 40EE to make the top look right.  Id return it if I hadnt worn it around already just trying everything to make it work. Would not recommend unless you're more top heavy.  Definitely not made for us pear shaped ladies.
