Ok, this is kind of a stupid question [I'm still to new to tPF!!] But, I've been in a Louis Vuitton store and tried the bags on. BUT- I am SOOO TORN between the Speedy 35 and 40 [I'm 5'11] So my question is, at an LV store can you actually put some things in a bag to get the full shape and look of the bag? I'm always scared to ask because of them saying something like "Oh my gosh no you can't do that!!" LOL. Help ? Anyone? TIA.
