Vintage rainbow stripe shortalls

Feel like a toddler again in these vintage rainbow stripe cotton pique shortalls that are seemingly homemade, in adult size, fitting a bum up to 42″. The top is lined in a lightweight striped cotton fabric, buttons behind the neck, and the two back straps are adjustable in length. The triple-strip elasticated waist can stretch to 34″, and the pant length is 26.5″ from the waist seam. Very good vintage condition.
