It is in storage or I would measure it--i will hazard a guess of bust 36, or medium. Please just write and I will try and remember to get the measurements next time I go there,.....This is trimmed with a satin ribbon, and so it picks up light. Very cute. VERY vintage....nice embroidery, too.........PLEASE NOTE,...I'm forced to add the flat rate to cover all zones! this is likely going to ship at one pound= 2 pound rate. If you are closer to CA, the cost is less!!! O love saving customers $$ when possible!!
