Perhaps for your next order get a SFS lace front....I think its invisible to the eye if done right much more so than thinskin.
But YOu are going to have walk around with an air of confidence...if not then people will pick up your nervouness and examine you more to try and figure out whats wrong with you.

So be like an actor and act totallly calm and normal. If the Thinskin is showing a line all the way around...try some Dermablend cover creme its designed to cover serious skin flaws...but I bet if you get the right colour blend for your skin...it will hide the line...then dab some dermablend powder to set it...and you'll be fine
