Guys: how should a girl approach you if there are interested in you?

[Effably]

For me personally? A little flirting at a distance to measure our interest and then if I am not approaching her but did respond well to the flirting she is welcome to just walk right up and ask me out, share her number so on.

Some men might get all insecure about being approached or simply enjoy doing it themselves so much they would feel a little robbed (although these men are quite few, most of us just feel flattered).
But in practically all cases, some smiling, winking, waving, playing with your hair and just overall having fun at some distance is the general go-to. That way you are telling him you're interested and he knows that approaching would be welcome. Similarly you can see on his reactions whether you approaching would be welcome.

Or did you mean very specifically once she is there in front of me?

The best way is to ask for help or comment on something the person said, wrote or did. Girls value comments on how they look more than most guys. Guys like to be noticed for what they add to a situation. They want to believe what they bring is noticed and appreciated. Rather than saying "I like you," say "I like this about you." Always be specific, so they don't have to guess what you mean.

If you don’t know the girl then no not at all. I get annoyed when people at my school class flirt with me that I almost never know. This is purely based on looks.

However a girl should approach me when she at least talked to me before and if the approach is based on your personality as well as looks if your hot to the girl.

There are many ways:

I had a girl once say to me after our first date, during a phone call, "Did you enjoy our date"? and when I said yes, she asked, "did you find me attractive and would you like to see me again?" When I said yes to both of these questions, she said "let's make plans" - and we did and still are together.

It was very easy for me to respond to her direct questions and I appreciated her asking them.

Depends on situations like what about urs situation?

She should do it in whatever way she naturally would. Disingenuousness is very off-putting. That being said, unless she does is shy-ly, unconfidently, and delicately, I probably won't like it.

If she looks like that ya.
If she's overweight, then no

[awkward_author]

She should either walk up to or text me, and ask me out on a date.

[Cowboy6666]

She talks and discuss on random things or important things and then it should continue all day

[magiusX26]

i can't speak for anyone but myself. openly, honestly, and direct. pretty much just like women expect men to ask them out.

[Avicenna]

All she has to do is start a friendly convo

[In_Trance]

the same way she would want to be approached

[lycanthrope3]

Just be upfront about it

[Wise4myage]

All she has to do is be friendly and flirt a bit.
