You want to ask for a lob but you do need to use tongs to get the effect. Have a look at you tube for some tips. The colour you could either go for ombré or balyage.
I've just had my fine longish hair cut in a similar style & i find it quite tricky to do the curl effect. I can seem to do one side fine but need more practise on the other. And the trick is to leave the bottom bit of hair out of the tong so it stays straight.
