Hi,
This is similar to my situation where i went from being bald (horseshoe ring on sides) to wearing a piece.But even though people i knew could see i now had hair it looked good and matched my existing hair,and i have plenty of grey in it to match my age,and low density.Many of those same people are so used to me now with hair,they couldn't imagine me without hair.

I think if you get a realistic density,and it matches your own hair,then a short style would work when you start going without the cap.You could even wear the cap sometimes over your piece,and other times leave the cap off,just so people don't see a big change quickly,or just leave the cap off,if the piece looks good people don't care,they are busy with there own lives.

Regards topcat.
