In response to the pictures in this thread; no, no, no, no, no, no, no, and hell no. Flower prints are for chicks and old couches. Maybe a real flower on your lapel or in your hat for a special occasion or as an indicator for a pre-arranged meeting with a stranger.
I have to return to the moustache test for this one. If you're worried the person might punch you, the moustache is legit. If the moustache makes you want to punch the person sporting it, it's a no. All over floral prints? Hell no.
But, this opinion is coming from a person that wears earth tone flip-flops, so feel free to disregard.
