Onyx Sizing

I know there's so many of these posts and it's probably getting annoying but with a drop like this I want to spend my money well. Anyway I'm 178 cm and 73.5kg which is 5 foot 10 and 162.04 pounds. Measurements say that I'd be an XS (Chest:96cm/37.80 inches Waist: 80cm/31.50 Hips:94cm/37.01 inches). I'm thinking a S so I can also have it for the future when I'm bigger but I don't want a baggy compression shirt yk what I mean?
