Excuse me

We are buying some sweaters to our daughter in NL.
The method recommended by her is the following: I take a photo of her in each piece and then on the basis of the pics she takes the decision.
I pop the question: what if she just takes a look directly in the mirror?
From her look I conclude it was the Ultimate Evidence of Misunderstandings cross Generations. 
I say a quiet ‘sorry’ and back out of the changing room with my eyes downcast.
