If the 45 fits the carry on specs then I will go with 45, otherwise I will go with 55 business.
both fit
Oh I guess where you are from have different requirements for carry on? In the US, both actually technically doesn't fit. (I just checked LV site for dimension.) But one can probably get away with the 45 because it is just 0.2 inches too wide.
If both fits then I will go with the 55 business.
well, I'm no expert
I just checked the lv site
and googled.wikipedia the permited size
and I have to say, the figue is a more unique color to me
but on the other hand 45 is small
