I can't decide between 29 & 33. Which is your preferred size? I've seen a 29 and its a nice size but I think 33 may suit me better (although not seen 1 and there aren't any in the stores I'm London). I'm 5ft3 and slim build so would the 33 be too large for me? I would use it as an everyday bag but I have young children so would like the option to be able to carry some of their stuff in the bag. The SA will call me when she gets stock but I think she is just on the lookout for a 29. Appreciate your opinions.
