I'm not a huge "hat" fan as my forehead's shaped funny (well, I think it does).
This winter became a rather challenging change for me as I moved to way way UPstate New York where 5 degree F feels warm, so I figured I need an extra protection for my head.

I just love this beret!
It's not completely wind-proof as it's knitted but I never felt cold wearing this hat.
It's light and loose so my hair doesn't get completely flattened and embarrassing after wearing for an hour either.
Lastly, it actually makes my forehead look nice. What an awesome little accessory!

I got the burgundy one, which is one of my favorite colors, and I think it adds nice color to dark and gloomy black winter outfit as well.
