Hi going through all the posts I didn't see the following advice.
"Before drinking from a glass or cup, give a area where your lips will be placed a quick surreptitious LICK, non-obvious to others.
The moisture of your spittle will prevent lipstick transferring from your lips the the drinking vessel.
Also I tried some permanent stuff and found it to be rally horrible, sort of gummy. Not for me thank you.
Next trick, learn to reapply without a mirror to make reapplication quick and less obvious.
It's NOT THAT tricky at all. BUT, if you use dark, or blood red, and such you better don't try that because it is far less forgiving for overpainting.
Lastly, what is wrong to congregate in the "powder room" with some other gals to reapply lippy? Always can have a littel chat --- I actually love it, going there in company :-)
