Help me choose!

Looking to buy some new suits from jovanadesign on etsy, and would love some recommendations for what you think my butt would look good in, there's too many suits to choose from on the store! Thinking of these to start and a couple more pending your suggestions! https://www.etsy.com/au/listing/1622889152/jovanadesign-tiny-3d-string-1-extreme https://www.etsy.com/au/listing/1811862805/jovanadesign-extreme-erotic-nano-men
