Dark grey is always one of my favorite winter colors. It allows me to give the "all black" a little break.
I have to fill me closet with oversized sweaters, because they are so warm, so easy to wear, so versatile and so chic. This one is from StyleWe and you can find it here, i love the back ad the turtle neck so much.
When i wear dark grey i really like to go monochromatic, so i very often match my sweaters with dark grey jeans, like this ones from SheIn.
To finish the look i always add some black detail, like the VIPME backpack that you can find here, the Locman watch and the Solewish boots.
