This is for next year so not after specific items, but maybe some ideas of retailers?
Every year with the kids I end up wearing a one piece as I've never found a bikini that feels secure running down the beach, doing handstand competitions in the pool etc.
Everything firm looking is basically a bra (black underwire with bra style straps = so dull I would rather wear a costume) or in a print my mother would call jazzy.
Does anyone know where to get good, firm bikinis. Quite busty, size 14 if that's relevant.
