So, let me disclaim this by stating I'm already in the market for a new binder because my breasts grew over the last year (

). However, I'm worried this issue will only continue to occur with a new binder.
I wear size large shirts and it's been awhile since I'm tape measured my chest but the last bra I've worn was a 40B. Given this information, I bought a large size binder from underworks (I believe tri-top specifically) and actually had to cut away in the underarm/pit area because it was giving me a horrendous rash; it was otherwise fine when worn. The problem was getting the dang thing on and off. No matter how much I tried to break it in, I'd end up stuck with my arms over my head and my wife rolling on the floor trying to catch her breath. It made me embarrassed and intimidated with binding so I stopped trying about 1-2 months in.
Am I really going to be stuck needing another person to help me bind or are there alternatives to my situation?
