Lots of buns are nice but..... Buns of freedom just make you flag fly a little higher.
I got a Large and my measurements are 40/27/38. The fit is perfect, the length is just right at my hips. There’s not much stretch to it, but it’s so comfy. I don’t usually wear a bra with it, since the flag protects and conceals the girls if it’s cold. Love this shirt. I also got the “sky’s out thighs out” and get compliments on it all the time.
