Two Kids Swim Shirts and One Trunk

The shirts are 16 and 10-12 but they look the same size. One is Columbia and one Cat & Jack. The only available trunks are the ones with the jellyfish in the separate pic. The two in the same pic as the shirts are no longer available. Trunks size is large 14/16. Brand is Speedo. I don’t remember the kids wearing them but I see they had a string that is missing. Not needed since they have elastic.
