My brother got married in 2004 and I needed some slacks for the rehearsal dinner. I knew I had gained some weight, but thought that I was just an 18.
So I went to the mall and it was obvious when I hit the first department store that an 18 was wayyy too small for me. The only place I could find a pair of pants that fit was at Lane Bryant. That was a shocker because I never thought I would get so big that my only clothing options would be at a plus-sized store.
So while I certainly wasn't in denial anymore, it still took until Febuary of 2005 to actually get started.
