I went through binge and purge cycles in my 20’s when I was a lingerie only CD. It wasn’t only purging. I tried to join the military but my bad knees kept me out. Then I took up body building and became quite big and incredibly strong.
I also remember all those embarrassed shopping trips to buy pretty things as far from home as was practical. I would travel at least 40 miles from home to shop for things. I once even rode a bicycle 40 miles each way to buy some lingerie only to throw it away a few weeks later.
I pretty much stopped purging by age 30 but was still a lingerie only CD. I also had a few very pretty satin bridesmaids gowns.
Once I dressed fully at age 35 all the purging ended. After that the problem became I could never get enough outfits, shoes and boots. I ended up at one point owning 17 pairs of thigh boots. I would go to a bridal shop and have the satin dressed I designed custom made. The seamstress was great and she even made a leather dress for me.
Once I actually dressed and was out in the world living a life as Barbie purging was no longer an option. Not that I would even want to at that point.
