Sunglasses and hats. I have about 6 pairs of sunglases and about 10 or 12 baseball caps. I never pay more than $5.00 for a hat, and when I buy sunglasses, it is usually a sale where you buy one pair, you get 3 free.
I also have two wallets that I have not used. Both are expensive, but, I got them for like $6.00 a piece on sale at 90 percent off.
I think there are lots of accessories that suit both men as well as women. Lets say a watch not all watch can be worn by bot sex but some are there meant for all. For sports fashion there sweat band his is used even as accessories is suited both male and female.There are tops and bracelets may be not girly type but some punk accessories are well suited for most all gender.
Ugg boots are apparently cool for both men and women, but is that an accessory. How about a diaper bag? It was important for us to find the perfect bag as we would both be using it. That's the only accessory I've shared with a women, that I'm willing to share with anyone. haha
I was watching this men's fashion advice guru on youtube, and he claims that men should never wear tighty whiteys, or white crewneck t-shirts, because it's not fashionable. I just watched this, and went...you're kidding...
