This ridiculous thing. On a primary school age girl (maybe nine?) Looked like it's made of polyamide (swimsuit material), was super tight and probably breaks about ten children's wear regulations.
She was hopping toward the water, with an adult wandering along behind.
Fortunately the lifeguard stopped them immediately, but I cant quite believe that the person with them (maybe DGD) was actually going to let her get in the water.
Was with another MNer when we saw this so apologies if she posted on this first!
