Swim shorts/ board shorts for bigger thighs??

Hiya! So I’ve spent months looking for some board shorts/ wider swim trunks/ swimmable basketball shorts that actually fit me but I’ve been really struggling to find ones that do. I’m pre-everything and my thighs/hips/ass are big enough that most men’s pants simply do not fit me or if they do they cling to my legs and make them way more noticeable. All the advice I’ve seen on here about swimwear just says to get any men’s brand but I just haven’t found any that works for me. It’s been months and I just want to feel like myself while I swim, any advice?

TLDR: Thighs too big, ass too fat, looking for board shorts but nothing fits, help?

(ideally I would love european brands if possible since I live in Spain)
