My favourite mascara ever is by a Japanese brand Isehan, it's called Kiss Me Heroine mascara, it's SUPER waterproof and amazing for straight, downward-pointing lashes as it holds a curl (you just need to curl your lashes first). Unfortunately not available on Sephora but I get mine from YesStyle. I also like the L'Oreal Paradise waterproof mascara (turquoise tube) which is available on Sephora!
Both need an oil-based makeup remover at the end of the day!!
