How do you ask your crush out that....?

you don't really know that well and never spoke to BUT have flirted with for 1 full year and she has flirted back (Staring at each other, smiling at each other, impressing one another with how we look/clothes, small conversation about a past assignment and she brought it up cause I'm shy, etc.) So how would u go about asking a girl like this (that u have flirted with but don't really know but would like to get to know) out on a date? Thanks for any answers :)How do you ask your crush out that....?
first flirt

then date!How do you ask your crush out that....?
Tell her in person (no myspace or texting).


Make it a casual question, as if you were asking for the time. Say something like ';Hey Im doing this and this on friday, wanna come?';


It takes pressure off of it being an official date. Try doing something simple and fun like roller blading or something. Later when you get to know each other better, you can ask her out on a more romantic and formal date.
dont just out of the blue ask her out a girls think thats freaky tlk 2 her first.tlka bout life like ask who she friends with tell her ABOUT your friends stuff like that
you should just ask her out in person or just write her a note and slip it in her locker
