Swimwear abroad?

Hello my daughter will be 8 months when we go abroad on holiday. Weather will be around 28-30c i expect. We will have lots of shade (pool gloat with uv cover, umbrellas, snuzshade) but im not sure what swimwear to get her. Long arm and long leg ufp 50 suit? Will that be too warm? Just a typical costume and lots of sun cream? Something in between? Thanks in advance!
