Navy Columbia T-shirt (worn as a rash guard) and Nike swim trunks set. Worn for about two years. The T-shirt size is M, which is 10/12. For reference, my child is slim and wore this when they were sizes 140 and 150. The logo is slightly cracked. Please check the photos. Regarding the swim trunks' waist, the elastic might be a little stretched out, but it might just be me ^_^; However, there's a drawstring, so you can tighten them. Please ask if you have any questions! Thank you for looking!
