Here you have an amazing vintage denim baby sleeper jumper. Looks like it's in great condition. It's so cute with all it's stripes, fake pocket flaps, red front buttons and crotch snaps for easy diaper changes. The snaps have all they're paint.  Tag is missing but it measures to be about a size 12 months. I believe it is 100% cotton.

It's about a size 12 months.

The sleeper measures 11.5" sleeves from collar to end of sleeve, 8.5" Inseam,  12" armpit to armpit, 23" in length. 

It's a great looking sleeper! Still has lots of life in it.
