My commute to work is one of my favorite times to people-watch. On the train, navigating the streets of NYC, waiting for the subway… You name it. Some of my best outfit ideas and style inspiration come from the chic people I spot in real life. When I see a standout find—say a fabulous pair of balloon pants or a perfectly tailored blazer—I work up the courage to ask where it’s from. H&M, COS, and Aritzia are the usual suspects. This morning, channeling my inner chic New Yorker, I did a deep dive into the best buys from H&M, COS, and Aritzia.
Ahead, you’ll find versatile winter-to-spring transitional pieces, like short-sleeve knits, cigarette jeans, practical sets, elevated basics, tailored cardigans, and more. Plenty of affordable new arrivals, spring 2026 trends, and cool girl–coded accessories (ahem, oval sunglasses, a scarf belt, and a bowling bag) make an appearance. Scroll on to shop 33 chic H&M, COS, and Aritzia buys of 2026.
