Long underbust corset with collar BNWOT

This absolutely beautiful corset was bought over 10 years ago and has been stored away for the last 8ish. Not sure of the brand, company probably doesn't exist anymore. (possibly alt noir since i have other corsets and they were stored together) No fabric, size, or maker tags. Lining looks like a brocade. Main fabric has a nice pinstripe detail. Very sexy business lady vibes. Waist sinches down to about 24 inches, so I would say no larger than a 27-inch waist for this style. I'm at 28.5 and it was a bit hard to lace up if you also want oxygen. If you're a standard small, this would probably fit. BNWOT
