Can I have this in a double zero?

After much delay, I FINALLY got to go to the MET to see the McQueen exhibit.  Now, upon arrival, i was immediately irritated as security started touching and looking through my Marc Jacobs bag.  Pet peeve of mine, nobody touches my handbags.  After that I was immediately directed to the exhibit (without asking)…I guess my high heels and miniskirt did not give the impression that I was trying to find some Monet.  I absolutely loved it, and I think all you fashionistas should visit.  Totally wanted some of the outfits- so I asked someone working there “can I have this in a double zero?” and “those shoes in a 5 please” … but apparently.. not for sale.  Go figure.
