Olivia Parker

The Women’s 2025 Striped Color Block Sweater from Colo Store is
ridiculously soft. Like, curl-up-on-the-couch kind of soft. The colors pop more
than I imagined, and the fit? Just right not too tight, not too loose. I’ve
worn it to brunch, work, even grocery runs. People keep asking where it’s from.
It’s become my go-to for chilly mornings and lazy afternoons.

James Wilson

They look sharp enough for the office, but feel like weekend pants.
I’ve worn them to meetings, errands, and even long drives and they never feel
stiff. Best part? They don’t wrinkle. I can toss them on in the morning and
still look put together by dinner. Colo Store nailed it with these.
