Recently the trend of having matching lips and nails has made a come back. Brands are releasing lip and nail combos in matching shades so you can follow the trend and look fabulous. It makes life a little easier buying both to match perfectly, however you could easily take your favourite lipstick with you to the store to find a matching nail polish.
This trend looks classy and is great to wear to a casting or go-see so that you match and are in trend. Red is a classic example, however you can do the same with nude nail/lips so that you're as neutral as possible at a go-see since casting director's want to see you as plain as possible for a job modelling. This trend is also great to wear for a night out with your friends and/or family!
