I order a lot on amazon, but rarely do reviews.  I loved this corset when I saw it here, so I ordered it.  I'm about 5'5 and 129 lbs with a relatively lean build.  I am a size 2/small (sometimes extra small) in EVERYTHING, but I took some of the reviewers' advice and ordered a size up to a medium.  I was so excited when this finally delivered, which was weeks before the approximate delivery date.  That was nice.

I tried it on; let me rephrase that: I draped the boned fabric around my torso as much as i could.  Even after re-lacing, the medium could not get all the around me.  I contacted the seller and advised them that this item is NOT true to size, American or European.  It didn't even properly fit my X-Small body form mannequin.  I can't imagine a place where a ladies' medium would only fit Tinkerbell.

In closing, it's a nice looking corset, if you ever get one that fits you.  My advice, don't order 1 size up - order 2 or even 3 sizes up.
