Used, in like new condition. Brand is Wolff Fording & Company. Size is 6C, which fits a small child, girth 42.5", give or take an inch.

*Girth is the most crucial measurement for one-piece garments, so it should be the primary guide for sizing. To measure girth for a leotard or costume, place a flexible tape measure at the center of one shoulder, bring it down through the crotch, and loop it back up to the same shoulder.  The tape should be snug but not tight, and you should stand up straight with arms relaxed by your sides.
