I went with platinum Elation and I'm obsessed. Not super high waist but mid and they are amazing. Highly recommend!!!
Tailord sportsmans, Devon-airs, Rj classics, or kerrits are nice
There's a Spanish brand called Zaldi which breeches are mostly high waisted. I think they have international shipping and they have really nice ones!
the brand Platinum sells comfortable, good quality high waisted breeches. ask around your local tack shops or you can also order some online if you know your size- try dover saddlery, it offers great sales online :)
