Vintage Baby Boy Romper Blue and White Preemie One Piece w/Hat 1950s-60s. This onesie is in good vintage pre-owned condition. The Onesie does not have a tag for size, but it is a very small size. It does come with a matching hat. It does have the rubber pants as shown in the detailed photos. Please see photos for condition and measurements as photos are a part of the description. I am happy to answer any questions.
