Set up a nice storage system for different seasons, and group your favorite pieces based on what works well together, that way your closet becomes less overwhelming!
There is always a coupon somewhere, and if there isn’t, just wait.
If a store has the same sales on schedule (like clockwork) then maybe the clothes are worth even less than the sale price. And worse, maybe the clothes are poorly made and hardly worth anything at all!
I make it a rule not to spend more than $50 on anything synthetic or blend. I prefer well-made, 100% cotton, cashmere, silk, whatever, because those are the pieces I will reach for when I am 50 years old.
If you are just starting to build your personal style, go thrifting! Buy secondhand and build outfits off of what you find.
