This is a Master Bunny cap. The color is white. It can be worn throughout the season. *I have inspected the item, but there may be oversights. Due to the white color, please refrain from purchasing if you are concerned about small stains. There is no major damage, but there is some wear and tear, so please refrain from purchasing if you are not comfortable with used items. There is no specific size. It is adjustable with a adjuster. I also have children's clothing (for boys and girls), men's golf wear (Pearly Gates, Munsingwear, pants), women's accessories, and fashion items, so please take a look.
