How can you not know that?

she does she just didn't think anyone else in the house would see it.

I think Abs is spot on, she clearly is very much into a "look" and will probably spend more time on that look than with others or doing tasks.

Maybe its something she'll grow out of??

she is not coming across well, endlessly moaning about the overall she is being made to wear and then asking Abs why he thinks she is superficial, she really can't see it?
