Socks. Personally I am a change every 2-3 days kind of guy.

expensive clothing brands

Buying designer gear from outlets is something you should definitely cheap out on. 'Fast fashion' prices with designer quality. I'm not at all convinced the designer gear was ever worth the official price tag but I am very sure that it'll last longer because you can't sell a pair of leggings for £75 if they're going to fall apart or bag out instantly (or at least, you won't get away with it for very long). Getting those same leggings for a tenner is the way to go.

Sad to say, they still use the same sweatshops as fast fashion brands, they just pay more for the quality control. So you still need to care about how the brands conduct themselves.

If you live in an area with a store like a dollar store/tree/general, getting snack foods from there is cheaper than going to a normal grocery store like Walmart. At least it is where I live.

I don't know if it's changed prices in other places with these types of stores, but at $1.25 for generic thin mint cookies, that isn't a terrible deal at all if you ask me.
