Does skinny really matter?

So just to put it out there, I am not asking this question to seek out compliments or anything

I just want an opinion on whether being skinny really matters that much?

I'm 5.6" and I weigh from 117-120, and I feel that my ideal weight should be around 110-112? but everyone I ask says that that's gross and I should stay the way that I am?

so basically my question is, is it more attractive when a girl is very skinny and toned, or if she has some fat?
