"Standard American is our unisex line. Most contemporary T-shirts are sized for the Boomer Generation (former hippies who are now in the "relaxed mode"). Our Standard American T-shirts are sized for two categories: Men of all ages who desire a youthful fit; and women of all ages who do not desire the form-fitting look of Classic Girl, but refuse to wear the oversized, unshapely T-shirts of the other leading brands. The Standard American line is designed in the same way T-shirts were in the 70's and 80's, when the Boomers were younger."
