1). Red lipstick is beautiful. It is classic, and it suits EVERYONE.
2). Of course different shades of red will be better suited for different skin tones but don't let arbitrary rules stop you. If you like the way a shade looks on you, wear it with pride!
3). Everyone is not staring at you. Red lips can be intimidating at first, especially if you're not used to them but I promise, you're the only one that thinks you look weird. I mean have you even been out somewhere and judged someone for wearing red lipstick? Of course you haven't, because you've got better things to do and so does everyone else.
4). If you love the look of red lipstick but are hesitant to try it for yourself, start small. Get a red tinted lip balm, get used to seeing yourself in that kind of colour and slowly work up to darker or brighter shades. Also, if you're spending the day at home, go all out, choose your most bold lipstick and wear it all day, and make sure you look in the mirror whenever possible and appreciate just how great you look.
5). Red lipstick should be worn for fun. It should give you confidence and make you feel amazing, just remember at the end of the day, no matter how great your lipstick made you feel, it could only do that because you're already amazing without it. The lipstick is just a fun reminder.
