I agree that unisex accessories have huge potential. I've seen many women wearing men's watches recently as the larger size is becoming more and more popular for girls. I think that this trend is also extremely applicable to winter accessories such as hats and scarves especially considering that neutral tones are very "in" for women's fashion and traditionally male fabric such as herringbone and houndstooth are quickly gaining popularity among women. Many high end as well as department store designers have been producing more and more menswear inspired clothing for women (tailored jackets, vests, etc). If I had to bet on it I would say that unisex accessories will only grow in popularity an demand.
