"We don't lie about fashion"

There were 3 guys in the shop today at the same time ( a rare occurrence). Two are regulars, they come and check what's new at least once a week, try on things and just have fun. The other one just discovered the shop and was on his cell phone telling someone about it. He is a self- conscious, incredibly beautiful man - dark skin, green eyes like pools of light. He tried on 2 green shirts. Had a hard time deciding which one to get, the one he liked had a green flower pattern. He asked the gay guys for advice, they said he should take the one with the green flowers because it goes with his eyes. He did. They said gay guys don't lie about fashion. I wanted to know what they do lie about, but they wouldn't tell me...
