Grunt Style Blue Line Flag Men's T-Shirt

What does the sleeve read with crossing rifles

I’m 6’ about 255lbs not muscular and I am wondering what size do you recommend for me?

I'm a female, 5'6", 145 lbs. and 39 inch chest, what size should I get?

How much do these shrink. My friend is 5. 6. And thin but unsure if i should get a small or med.
