CupShe? SHIEN? Plus Sized friendly?

V

I’m wondering if those cheap websites for bathing suits like CupShe ans Shein are plus size friendly? I’m like a 16 or so, and I have a lot of mid section (and BOOBS) so like XXL/XXXL are my top.

Are they actually good to size? As a bigger hooman am I likely to actually fit into the things I buy? There are sooo many cute things on CupShe I want bathing suit wise but I scared size and quality wise.

Thanks in advance beauties!
