Advice: Adapting Buttons on Pants and Shorts

Life would be so much easier If buttons on pants/shorts didn’t exist because it’s hard for me to button pants and shorts so before I put them on I button them and then I have to get them over my big hips and butt haha. I can button my pants ect but I do struggle a bit especially because I basically use my right hand for everything. I can use my left hand a little but it’s difficult since my left hand is my affected hand. Anyway does anyone else struggle with this or have any tips to make it easier? :)

Until I could master buttons on pants and shorts, my grandma used to take them off and sew on Velcro in their place.
