Variety, change or sink

why is it that all mens items like bathrobes or pajamas must be of dull colors? Navy, Burgundy, White plaid...etc..etc..How about a Charcoal color bathrobe? or a chocolate or espresso color? or beter yet... a Black one? why mens garments must be square, plain, "grandpa looking"? I look at any guy's bathrobe and it seems I look sick in any of them. Like I have a cold or the flu... How about deep green, forrest green, electric blueblack and white, "rad" monograms etc... spice it up a bit guys!!
