33 Trendy Basics From Reformation, COS, and Aritzia That Are an Immediate Yes

When it comes to basics, my thinking is that they don't have to be boring to qualify as basics (although boring ones are essential too). Adding trendy basics to your wardrobe is a great way to keep it fresh with items that can be worn in multiple ways and with different items. There are certain brands that do trendy basics very well, and I've spotted a number of great options from three, in particular, that I need you to see.
Reformation, COS, and Aritzia are a few of my go-to brands for trendy basics, and as we shift our mindsets to 2025, I'm getting rid of my tired basics and taking stock of what my closet needs in the new year. Since sharing is caring, I'm divulging my best finds from each brand so that you, too, can do a little productive basics shopping.
Read on to shop 33 chic Ref, COS, and Aritzia basics that subtly reflect current trends while remaining wearable and versatile.
