Serious Question: How Isn't Every Single New COS Item Out of Stock Already?

COS is one of those brands for me that I can always count on to offer at least a few items that check off all my boxes. Whether that's just a striped T-shirt, great pair of jeans, or an easy, everyday dress, it doesn't much matter. As long as I know that every time I type cos.com into my browser search bar, I'll find something worth buying, I'll keep coming back for more. Well, lately, the frequency at which I browse COS's website has been more of a problem than an innocent behavior, and probably not for any of the reasons you're thinking. The issue? Everything is too good.

Whereas I once might find one, max two, COS items to add to my shopping cart every time I looked, lately, that number has increased dramatically. Its selection of outerwear, dresses, shoes, pants, and most of all, bags, has me spending far more than I should. I just can't resist, and the worst part is that when I receive my purchases, they're even better than they looked online, sending me back to the site to browse and creating a never-ending spending cycle. My financial advisor is not happy with me. My wardrobe, on the other hand? Thriving.

That's all to say that COS is on a hot streak this season—hell, this year—and I can't, for the life of me, understand how every new arrival that lands on the brand's site isn't already sold out. Clearly, people aren't checking as often or as thoroughly as I do, which is why I've come here to change that. Below, find all the best new COS items for summer 2025, from elegant scarf blouses to expensive-looking dresses. There's also swimwear, basics, and lots of purses (my favorite category from the brand right now). It's all just a scroll away.

If you've been on the hunt for flats that give heel energy, I found just the pair for you. I have them in black and wore them throughout my recent trip to Athens. They make every outfit look refined and chic, without any of the pain of heels. I also packed them for the trip I just returned from in Seoul, and they garnered tons of compliments on the city's streets.

Shop the flats:

Basically, this entire outfit is COS, from the shoes to the capris to the blazer. The blazer, especially, is such a cool statement piece, mostly because of its unusual shape and texture. It almost looks like denim, but is actually a heavy woven fabric that feels super expensive.

The second this bag arrived at my desk, I took everything out of my "before bag" and put it in here. It's been my go-to ever since, toting around all my essentials (and then some). It fits far more than it looks and because it has no visible hardware, you can pair it with gold or silver jewelry.
