Modart vintage back lace corset

This Modart corset is from around the 1920's. No fabric content. Pretty pink/peach color jacquard fabric. This is, I believe, a breast flatting corset. Very popular in the period. It has 4 hooks at the top of the back and 4 rivets and hooks at the bottom. Elastic inserts on the back sides of closure. It has a total of 8 stays. There are some numbers stamped inside the stay lining 697 26. The 26 is probably the waist measurement since that is the measurement I'm getting. Laid out flat it measures 36 1/2" across under the arms, 26" at the bottom. Of course with the long laces it will fit a larger size. It in very good condition. The only issues I can find is a couple of faint discoloration spots and the trim at the top of the lace up back strip is loose at the top. It does not appear to have been worn. No fabric wear or stretching. I ship same or next business day.
