Cotton on 

To realize or catch on to something - usually something in the past which you should have figured out at the time but didn't; Scottish slang.

She was giving all kinds of hints that she was interested in me, but I just didn't cotton on until I got home.

Cotton On 

100% that Aussie brand you're always bored-scrolling and have 52 items in your cart. IYKYK. Somehow every mall trip ends up here and you're rifling through the graphic tees (decisions, decisions), trying jeans you already have (but in a different wash), another pair of leggings (these have pockets though), and playing with the accessories (is this the new me?). Suddenly you're thirsty, but it's okay cos you can grab a chilled water (and support the Cotton On Foundation!). At the checkout, you get 5 tote bags, cos you can't decide on one. And then you're really * done * with IRL shopping (for like 2 weeks). So you go back to scrolling again.

I got this top from Cotton On.
- Huh? Is that a cotton supply store?
No 🙄
