Vintage 1950s 1960s Blue Knit Baby Romper

Darling baby romper from about the 1950s. Sweet one piece in blue with little buttons for the straps. Probably mostly intended for a boy then but would be unisex now as well. Very soft and cozy knit. Looks and feels like an angora or mohair or similar. Label reads: none. Please see my measurements below because I'm really not that familiar with baby sizing but I'm guessing this is about 0-3 months or so. Would be very cute for a doll too.
Near mint vintage condition.

Measurements: doubled across bust, waist and hip.
Armpit to armpit across the chest: 16" to about 23"
Waist: 15" to 23"
Hip: 22" to 30"
Shoulder to bottom of crotch: about 14"
