Why is this girl always asking me for opinion? she is my friend for almost a year and she just keeps asking me random questions? why me?

Anonymous
She (16 y/o ) is my classmate and when we are in school she is always asking me how her dress looks or how her hair looks or how whatever she brought looks and many more questions like that. There are so many girls , she can ask any of those girls but she just ask me.
There are so many guys in our group but she asks none of them. It's always me.

Why is she so concerned about my opinion? it's getting a bit annoying how many times do I have to tell her she is really pretty.

The other day I went to her house to give her some notes and she dragged me all the way to her room to ask how it looks.

I am a man of few words , I really can't come up with things to say.

Is it normal for people to be asking questions after questions from only one person like this? Or is it just my introvert ass which can't understand how people behave?

Apart from this quality , she is a really sweet girl. She is pretty and tops in every exam. I just can't understand her obsession that's all

update 2 : it's not always about her appearance , it's about any random thing. like whatever we are looking at , she is like " what you think "
