“Little Dude” sweatshirt romper

Light brown sweatshirt material romper. Two buttons on one shoulder for easy slip on over baby head. Three buttons at the crotch for easy diaper changes. The boutique I bought it at said it’s ok to wash in cold water, so it has been washed once and hung dried only. Fits comfortably at 3 months old although when I bought it, it said 3-6 months on the boutique tag. My son is 3 months old in the photo shown in the post.
