I have seen a selection of Large cap wigs on En Femme.
The least expensive option is $166.
You can also go to an actual wig shop. I’ve been to a few and if the staff is professional, they’ll have no issue dealing with a person like us.
I had a good experience and invested in a decent wig for $120. I’m at about 23.5in myself.
Also, pro shops can easily stretch the cap for you overnight, they did for me on the $120 wig. I ended up going back to them for a second (short) wig and they did the same. By helping me try diff lengths and styles, and by making the wig fit well, they earned a loyal customer.
I’d give some serious thought to trying a local-ish shop. Call ahead if you’re unsure and ask if they would have any issues serving you. Also, bring a blouse… I did this and they encouraged me to change in the back after I arrived. I could see how the wig looked in a blouse with the wig on…it helped.
Good luck honey,
