vintage speedo matching set

omg this is the coolest set! vintage speedo matching set, windbreaker material, not tagged so i’m not sure what size but i’m guessing it’s a boys small or medium. i’m 5’3 and this fit me up until last year, it’s now just too short on the arms and legs so would most likely fit someone around 5’0. the pants have a draw string and zippers near the ankle. i wish this fit me still because i absolutely love it. small stain on jacket you can see in the last photo, but probably would be easy to get out.
