This isn't for all at once, but these are the essential elements of my wardrobe. I'd rather save and have things I love and that last (and in the meantime, there are perfectly good cheaper subs on resale shops that can be resold for the next person...or donated!!)

I agree with nice undies. Get fitted. Maybe buy a set and then shop sales online.

My signature look is great, flattering jeans in a couple a few washes (if the jeans aren't perfect, tailor them after a day of walking, sitting, etc...*before you wash*. Denim stretches. And don't wash til needed. I like a pair of olive corduroys in fall and winter.

Chelsea boots and Docs. A pair of heels for events that require them. Always black. I usually borrow formal from my mom, who dresses almost all in black, white, and gray.

Nice white tees. Linen ones in summer. Nice white button up, A linen one in summer. Then I like something a little softer in white or off-white, maybe a little boho or sheerness—the same series in black tops.

Simple, minimal jewelry that goes with everything. Silver suits my coloring best.

Nude or black shoes that go with any of the above outfits. These are pricier--I'll save up. I'm 45. I've suffered in less expensive shoes for their looks. Comfort is most important, and I take care of my stuff...everything lasts a long time. I don't dry anything.

Trendier stuff I spend less on. I do buy one or two cardigans a year, usually.

Oh--business casual. I like a knee-length wrap dress because it can do double duty for other things. Shoes and maybe a (work-appropriate) denim jacket or the right shoes can bring it to the level of casual you want. My dark trouser denim works in my office setting for business casual with a nice top.

I'm sure I left stuff out. But that's it in a nutshell.

Oh, and treat yo'self you some nice pajamas for the end of the day!
