The etiquette experts say that you should play around with your makeup in private, but Rihanna
Not that the superstar committed a crime, but there she was Friday night at Jay Z's 2015 Throne Boxing Fight Night in New York, in the middle of a big crowd, in the middle of a big boxing match, and she whips out her tube + compact. And the shade is in bright, bold red. LOL
We love her makeup look, by the way...Gorgeous cool, simple cat-eye + bold, red lip. Nothing over-done . Quite elegant.
And Emily Post, the grand dame of etiquette, would be applauding Rihanna for the quick lipstick re-apply in public BUT---only if it's done WITHOUT the compact, done very fast and done in the company of a small table of friends:
"In general, personal grooming should be done in private for the simple reason that it can be annoying and it's tacky. ... When in doubt, don't do it, such as when you're at a business meal or with people you don't know very well."
