I stretched to a 00 pretty fast, ended up removing them because I was looking at jobs that it was frowned on even though long hair covered them. 0 is kind of the typical point of no return as far as closing on AVERAGE although every person is different. I personally say do it and go to 0g.
Oh, and I had flesh colored plugs that weren't very noticeable especially with hair about to the bottom of my ears that worked temporarily when I was going to elementary schools for work.
