Fashion style changes all the time, but there are some items of clothing and accessories that will always be fashionable. For example, a black wool jacket that you can dress up or dress down, a black cardigan, or a pair of black boots that you can wear with a skirt or pants. Here are some winter essentials that I think are worthwhile to invest in for your wardrobe.

Wool Toggle Coat –  We can never have too many black wool coats for winter! We need a formal black coat for the holiday parties and special occasions, we need a casual black coat to pair with our relaxed outfits, and we need at least one more black wool jacket that can go with both semi-formal and casual attire. And for that, I recommend a nice wool toggle coat. (The JCrew coat shown here is sold out. Try Burberry Brit .)

Cashmere Sweaters – I am a big fan of cashmere sweaters for fall and winter, because they are soft on skin and keep me warm. I have a collection of cashmere sweaters in various colors (such as purple, red, green, etc.) and in different styles (turtleneck, v-neck, hoodie, etc.). Out of all the cashmere sweaters I have, there’s one I wear often, which is a black cardigan by JCrew. )

This black cashmere cardigan is great because it is so versatile. When I wear short sleeves/or a sleeveless top in summer, I would bring it with me in case it gets colder during the night. Smething similar is a must-have for anyone’s wardrobe.

There’s another cashmere sweater I highly recommend. And that is a turtleneck sweater in black. I have one from Ann Taylor for several years now. I don’t wear it very often, because winter is already a bit gloomy for me and I prefer to wear colorful cashmere turtlenecks sweaters (such as in pink and orange) to brighten up my days.

During my past holiday trip to Seoul, I brought my black cashmere turtleneck sweater because I thought it would be easier to match with anything I packed for the trip. I wore it with my skinny jeans plus my Frye boots, and wore it with my boot cut jeans with my UGG. The black cashmere turtleneck sweater instantly upgrades the look of my casual attire. I was very glad I packed it in my language!

A Pair of Frye Boots – Another essential item for the winter is a pair of black boots. I’d recommend my favorite, Melissa Harness Riding Calf Boot by Frye. It goes well with both skirts and skinny jeans.
