Students Clothing

[snapes_rose]

HI Everybody,
I just got here because I have been wondering about something in the 
Movie:
Student Clothing

This is concerning the Students Clothing,if this had been disgustet 
already I apologize!!

In the movie, everyone(the Students) went shopping before they get to 
Hogwarts and get sortet, now after they got sortet had their Meal and 
went to bed we can see Harrys open Suitcase how can he have already 
Griffindor Clothes if he went shopping *before* the Sorting! 
Just like the other Student, all the 1st year Students had the 
Clothing Color of their Houses.

Anybody???
