Rugged Butts onesie

Summer seersucker vest one piece. Made of 100% super soft cotton. New with tags. There is small yellow stain on one sleeve—not sure how it got there as this hasn’t been worn and has been hanging in my sons closet but he outgrew before he got a chance to wear it. I would imagine it will wash out. Vest is sewn onto the onesie. Size 6-12 month.
