SweatyRocksWomen's Color Block Butterfly Print Striped Long Sleeve Crop Top T Shirt

I'm a guy, 6 ft and about 175lb, what size should I get? the size chart doesnt have an option for long sleeve crop tops

is the crop top separate from the long sleeve?

I'm 5'4, 125ish lbs, 34 B bust, 27 inch waist. What size should I get?

Can a guy wear this?
