Closet redo!

I feel like I need to redo my entire wardrobe, help.

I just got an office job and I would like to look semi cute everyday. I don’t need to dress up fancy or anything, but I would like to look nice. I have had the majority of my clothes for 1-5 years and I just feel so gross everyday.
Nothing fits properly or fits In a stylish, modern way.

What are easy, affordable ways to redo your closet when you feel like you like nothing? What should I concentrate on? How can I develop a more cohesive, well fitting wardrobe?

It’s really starting to negatively impact my self esteem. I’m assuming other people know how I feel.

Looking for any and all advice thank you!
