Wear black if you can't decide how to put together an outfit-- black goes with ANYTHING.
Oh, and if you're afraid, DON'T SHOW IT. No one likes a scaredy-cat. ^_^ Just be confident! You shouldn't look at the floor or stutter. Also, make sure to wear clothes and colors that draw attention to your facial features. Lip gloss can help, too. :) Good luck!
Chew your lip a little. I hear guys like that. (I don't flirt, so.... yeah....... um, well I hope that helps!)
IDK I've never flirted before Dx
you should walk up to him and introduce yourself to him (always keep a smile on your face) laugh at all his jokes spend a lot of time with him and you have to always be confident and complement him on how he looks. and try to make him laugh.
Lot's of these have good ideas... I think they've covered about all of it! XD Haha. I'd love to add my own idea but as it seems I'm having the same problem as you- Just can't flirt! I guess popularity ranking doesn't help much with these type of problems, but oh well. And The_Caged_Bird was right about the fine line thing. And as said before, confidence IS everything ;) Good luck!
on the fliting thing well...im not big im fliting but i can help ;) okay if he is going to walk down the hall or where you are in "exidently" drop your books and a book but make it look real when you go to pick it up if he helps he is either being nice or he is in to you. but BE YOUSELF! make some jokes stuff like that good luck :) (im going to try the drop my books on momday xD)
Make sure you laugh at the person you like's jokes . I mean , if you like them , your laughs wont be fake . You dont have to impress them with your looks , but atleast look decent if not more . Tell them funny and interesting stories about you ; they like it when you feel comfortable around them . And Be REALLY NICE .
Ohkay this is how I do it:
Before i go up to the guy, i make sure I look good, hair, make up, breath, anything that would be a total turn on.
Go up to him grab his hand and just start talking about things. Like about things that interest HIM.
Get close to him, dont make it awkward cuz then he wont be interested. . . AT all!
Just be yourself around him, smile and laugh with him, make jokes. Be confident too, that's really important. I know it kinda sounds like I barely gave any informatio., but really it works just to be yourself. Good luck! :3
