My Co-Worker Just Sent Me 3 Mega-Chic Winter Outfit Ideas—Prepare to Take Notes
Sponsor Content Created With Cos
Okay, if there's one person who can convince me to buy anything, it's Lauren Eggertsen. Seriously, any time I see our stylish editorial director post anything—an article on-site, an IG post, or even a link in our Slack channel—I'm instantly sold. While we were hanging out in L.A. recently, she mentioned that she's been finding a bunch of really good new pieces from COS that hit that sweet spot between effortless and on-trend. Naturally, I asked if she could send me a few links to the things she's declaring most worthy of adding to her cart, and let me just say, she really delivered.
Not only did Lauren send over the links, but she sent three whole outfit ideas, plus styling tips for good measure. I'm talking everything from lug-sole boots and sweater-vests to wide-leg trousers and teddy coats, and of course, I want it all. So if you're looking to add a few new pieces to your wardrobe, keep on scrolling. Your winter outfit inspo is all right here.
"This outfit is likely the most 'seasonal' my L.A. winter aesthetic will ever be, and that's probably why I love it so much. I have been living in relaxed trousers lately, and this pair just became my new go-to. Paired with a delicate turtleneck and a cozy, fuzzy coat, this outfit really proves it can do the most without being too fussy. It's comfortable, stylish, and filled with all the most idyllic winter pieces. The fact that this look is composed solely of 'trendy basics' is why I love it so much. Each piece feels extremely current, but they are simultaneously items I will have in my wardrobe for years to come."

"This outfit is so fun to me because it's tapping into that academic trend that, up until recently, I had been too nervous to test out. I love this pleated midi skirt so much but wanted to toughen it up a bit. Since I decided to pair the skirt with a sweater-vest, the whole ensemble was reading a tad too academic, but the lug-sole boots saved it. I love outfits that can be completely transformed with one contrasting element. It always makes a look so much more interesting."

"Tailored vests and blazers are all I can think about right now. I love how sleek and elevated they look, even when paired simply with jeans. It's dressy enough for dinner and chill enough for a day of running errands and hanging out with friends. The kitten heels help take the overall look to a more forward place, and the vest is interesting enough to turn this monochromatic look into something really special."
