Trans Equestrians

Any trans equestrians out there? After taking a 6 month recovery break from English after a fall, I’m getting back into riding. Primarily, I’ll be going into western to save me some dysphoria about English being a “female discipline.” But I also started working at a barn as a groom, and I’ve been asked to ride multiple horses for sales videos. They are English horses, and I have nothing to wear- all of my previous clothes were more feminine, despite me having ridden while I was also trans. I can’t seem to find anything that I pass in, any ideas? Also, keeping in mind that I am cursed with living in AZ summer heat right now- so unfortunately I can’t wear hoodies/jackets.
