Laughing at Linda (milehighstyle's) comment. That is probably what Mr. Suz is also thinking. Don't criticize -- she might replace!!
Actually, he sounds a bit like rabbit's SO. He sometimes raises an eyebrow or looks doubtful about a new silhouette. But typically, if said fashion-y item actually looks good on me and he sees that I'm comfortable in it, he is on board by the second wearing.
He is completely on board with short hair on women, fluid fit, BF jeans, etc. He actually dislikes too much body con as a rule, although he does love my body con Kamalikulture dresses.
He buys his own clothes but always asks my opinion. I'd say we have about an equal say in one another's wardrobe. We listen to one another especially about fit and if the fit is off, it goes back or gets altered. That is I guess his main poison eye (and mine) -- poor fit!
He listens to me also about colours. We do tend to agree on this, though, so it's not usually an issue. It's just that he sometimes likes me to affirm what he is sensing.
I have a poison eye for Birkenstocks but he has always worn them and still does as house slippers.
I also have a poison eye for his current frameless specs, which I think look horrible on him. But he hasn't found a comfortable replacement.
