Swimwear brands on Amazon that aren’t totally cheap??

I found out very last minute that I need a swimsuit for a work retreat. I’m in the awful position of finding out that my existing suit no longer fits and having only days to try to find one. In the middle of winter. While sick enough that in person shopping would be a challenge.

I tried ordering from regular sites with expedited shipping, and none can get things to me in time. I hate supporting Amazon and fast fashion but I’m left with zero choice.

I just want to find something that’s sturdy enough not to completely fall to pieces and be a total waste, and normal enough not to embarrass me more than I already will be. I’d love to hear brand recs from ones you’ve personally tried and why they were good - Amazon reviews are super generic and fake as hell, so I have no clue where to even start.

Asking for style-specific recs is likely too much at this point, but just in case…. I’m looking for a one-piece that won’t make me look like a grandmother or a 12 year old at a swim meet, but also won’t show TONS of skin. Preferably black. I’m an unfortunate pear shape between a US size 2-4.
