Vintage early 1900s black wool skirted swimsuit, no brand tag. It appears it was later modified with rope straps and side/back panels. There is no size but measurements equate to a large. In very good condition. Some previous repairs were made in the crotch area and just a few small holes which are shown in the photos. The straps are long and adjustable. 

Measurements (lying flat):
Underarm to underarm about 17"
Waist 14.5"
Hips about 16.5" 
Length from the highest part of the bodice to the hem of shorts about 30"
