Sometimes when outside is such a grey sky the only thing you want is to hide at home in cozy sweater and with a cup of tee. I agree with you, but we don’t choose weather, so we have to accept that. All you need is something that will provide you warmth: as I already mentioned knit sweater, warm boots and something to cover your head. I must tell you beanies and women’s head covers are essential accessories for women who live in cold climates.
The thing is, if you feel depressed, then you have to choose something fresh and colorful to cover your head. If you are young, i advise you to choose hat, cap beanie or beret in lovely colors. Beanies are so practical, they can be casual, as well as classic. They look perfect, while you are on your way to your work, while shopping in winter days and what I like the most about beanies- they match with all kind of clothes.
