four things about makeup:
1, GGs get lots of makeup practice and input from being children so they know what works with what colouring/outfit/hair/occasion.
2, all women know that every other woman experiments with makeup and goes out looking silly/awful/inappropriate.
3, because of 1 & 2, no-one will say anything about your makeup - at least to your face - though you will notice all other women studying it closely.
4, because of 1,2&3 it is OK to compliment other women about their looks and casually ask if your makeup is Ok especially as you have to cover the portwine.
