Details

Brand - Olga

Content - 100% Nylon

Size - Labeled Size M, approximately a modern XS-S but please check all measurements to ensure fit

Chest - it's hard to measure because of how it is designed sort of open. I think it would work for a variety of chest sizes. It is 20" across pit to pit but that doesn't exactly hit at the underarm 

Empire Waist - 12.5" across, stretches to 17"

Hips - approximately 39" across

Length - 53", The bodice is approximately 12" 

Condition - I didn't find any holes or stains but there are a few small nicks to the nylon as pictured in the last 3 photos
