Its a fantasy world tho not medieval earth- no reason they couldnt come up with those swimsuit designs, or surfboards made of wood- nor the umbrella- nor a straw, as long as its not plastic.
You can't say surfboards and the umbrella design or the swimsuits are 'modern' designs- because its not earth. They coulda come up with them at any point on whatever that world is called. They dont need any advanced production methods they shouldnt' have.
The only things I would say are outright 'not possible' for a fantasy world without modern tech- is the phone and the things that HAVE to be plastic- i.e the beach ball and floats.
Ofcourse the items you pointed out DO all make it LOOK 'modern' to us rather than fantasy like.
