Likely to cry? Go for waterproof everything, in particular, your mascara. Hooded eyes? Look straight ahead, and create the illusion of a socket line by using a deeper shade of eye shadow in your crease line and pay lots of attention to your lashes. Hot sweats? Pack some translucent powder, or even better, some oil-blotting papers.
