Underwear

Don't show your underwear, unless you really want to. Maybe that sounds a bit stupid, but have you ever seen a girl on Gossip Girl showing her bra straps or maybe some lines underneath her shirt? I guess you don't except for the picture shown above.

This is not only a rule for becoming a gossip girl, but also a good rule in general for girls. Showing your bra straps is up to you, but when you're showing lines underneath your clothes because of your underwear, you're not wearing the right underwear. Most likely it's not your size. Probably it's too small. Remember, it's more embarrassing showing lobes that don't have to be there, than wearing a bigger size of underwear. Clothes in general by the way.

Back to showing your underwear on purpose. You see Serena is showing her bra in this picture, but done really tastefully. First of all it's summer and everybody is showing a little more skin than usually. Second, she is not wearing the smallest bra you van imagine. So there's a contrast what makes it sexy, but tastefully.
