There are 2 buttons on the straps Brand - Unknown, no labels inside Size - approximately a modern Medium but please check all measurements to ensure fit Chest - 18" pit to pit, stretches to 20" Waist - 14.5" across, stretches to 16" Hips - approximately 16.75" across, stretches to 20" Rise - 9.75" Inseam - 1.25" Outseam - 7.75" Leg Opening - 10.5" across, stretches to 12.5" Shoulder to Hem - 27.5" Shoulder to Crotch - 30.5", stretches to 32" Condition - The inner bra was carefully removed by a previous owner. A lot of times these get very stiff so I'm guessing this is why it was cut out. I don't see any other flaws
