Fits 36/38D/DD well, I had it altered to slim the rest, please see measurements! Could easily fit much larger as I tied it very tight. Could be let out to original size, I don’t think it would compromise look bc imo it is not faded but unsure if material would be compromised due to heavy duty stitching. Great condition other than some do marks on armpits. I wore this for Halloween events and tied it really tight. This is VERY well made and durable with a LOT of tension. The thick rope ties could be easily changed out if you wanted a more delicate look. Boning is adjustable. This is a REAL corset!
