My boyfriend constantly criticizes my outfits?

He often tells me that I either dress like an old woman, or that the stuff I buy are just ugly. He doesn't criticize just me, he also sometimes comments the clothing of girls on the street, saying they don't know how to dress, and that they either look slutty or ridiculous.

My style is roughly the same as these:

I never expose myself too much, beside the ocasionally short short, no plunging cleavage, always clean, never mix many colors or patterns..

I don't understand. Is there something I'm missing here?
