With friend’s visit?

I agree with other posters...if you backtrack and allow her to stay...she'll 'borrow' your clothes anyway and "could you just be a sweetie and sort out my hair" etc etc.
Say you're out of town that night, last minute plans ( no need to elaborate). But looking forwards to meeting her at 10am at Costa in town.
If she wants to have a hair and makeover day in town another time, why dont you book something for the new year and I'll ping you my share over, bound to be some deals in the new year !. This of course will never happen because you are the friend that brings the magic she enjoys....

She's a ponce. Be politely unavailable. Whoops, sorry something came up. What was it? Sorry, it's a family matter and I can't discuss.

This says everything you need to know really. You’ve done the right thing!

Exactly. And I speak from experience, I used to be a chronic people pleaser and attracted people like this in my life.

Tell her the truth . You really don't fancy all that hassle with hair/clothes / bath after a day at work . Ask her to just keep it casual . No meal at 9pm , breakfast tea and toast and show her where the milk is for cereal. No bed sharing sleep on couch .

This. I can already sense OP backtracking. Users are attracted to people like you OP, like moths to a flame. I bet she doesn't have many other friends because they've probably binned her off.

I had a pushy friend. Her reaction if I said I wasn’t up to this sort of situation would be to find a way around all of my reasons and express lots of disappointment to make me feel guilty.

You’re best off being less useful to her. Don’t go overboard with hosting, do the bare minimum. Say you haven’t got the energy when she wants her makeover - I bloody wouldn’t after a long day out. Pay attention to how she responds. If she’s a good friend she won’t whinge and whine.

It's all about her, she expects you to do all the work. Suggest meeting on the day, don't host her, she's a CF.

In the nicest possible way, grow a backbone

I think it's time for you to reconsider this friendship. Not all friendships are meant to last.
Personally, I'd cancel her staying over with a good excuse. Her reaction will be telling.
She comes across as the kind of person who will drop you like a hot potato once she realises she can't use you anymore.

Cancel as others have said - seriously I've had years of doing this sort of thing and some of the friends I went out of my way for in my twenties I now realise were not really friends. Even now I feel slightly bitter about the times I really put myself out for people - out of duty, kindness, social responsibility, worrying about not being a good friend.... and years later I can see what a waste of time it all was.
You can have a really good trip out on an equal footing and you'll enjoy it far more. Say no - use the suggested wording above and you'll be fine.

There is a backstory where I tend to constantly have to pay for her so feel like there’s a lot of take and she isn’t there for me much.

You don't have to do anything. Your choice

She isn't a friend, she's a user. The little enjoyment you get from this relationship is outweighed by the negatives. I would seriously consider going forward with this "friendhip" now you're in your twenties. People outgrow each other all the time.

Just make a point to always see her outside and always be "short of cash" when she's around. I honestly would not stand to be around a "friend" like this but I'm older and less tolerant about people treating me like an atm/doormat.

She's a user.
On this occasion she is using your hosting as an photo opportunity for " the gram"!!
Tell her she can no longer stay over as " something has come up".. you don't need to say what.
Then add you're looking forward to your day out( or go by yourself if she makes nasty comments)
YANBU

She sounds like a bloody pain in the arse, immature too.

Just text her and say something has come up so she can't stay at yours so you'll meet her in X place at Y time.

You could say - I'll meet you at the station instead of mine, as I won't be home early enough for a sleepover. Sorry about that. See you Thursday.

Don't change your mind or explain yourself to her.

You have work thing for tomorrow evening, so she can't come.

Or if she does come, you don't do all that stuff for her (why on earth were you doing it??). She sleeps on the sofa, dinner is fine to make, but breakfast is just whatever you normally have. You do not spend your evening washing her hair, styling it and taking photos of her in your clothes! That is not normal. Adult friends sit around and chat and drink wine/tea, they don't play dress-up.

Do you want to do the next day thing?

Don't cave in! The chance of you getting those clothes back is very low, for one thing. Tell her something's cropped up - work, family, anything - and you'll have to cancel everything.
