I am listing a navy blue swim cap. It is new but has been tried on and has been stored for a long time. My son is a slim, small-headed upper elementary school student, and it was tight on him, so I believe this cap is for toddlers to lower elementary school students. The head circumference is 20.5 cm when laid flat. The pattern is cute! I would love for a child born under the Aries sign to use it. Thank you for considering it ☆ #swimcap #swimming #pool #swimmingcap #waterplay #nurseryschool #kindergarten #elementaryschool #navy #aries #Aries
