This corset was made by CORSET STORY TM UK and is a UK size 10. i checked google and they say that's a US size 6-8. There is a purple fabric in the back that is 7 3/4" wide, so you can let the strings out some. Or you can tighten them up. A video i watched had the lady thread them differently. Hers pulled tight in the middle from the top and the bottom. it seems to measure 33" -26-34. it is very good quality and will last you for awhile. i think it's wonderful. cotton. steel. poly-cotton lining.
