each of them is gorgeous, but if i HAVE to pick one,
brief w/ gsh
i had a city wth gsh and i sold it, because the giant hardware made the bag look kind of crowded and i think most of people prefer the city with RH (this was a poll, i just saw it like 2 days ago!]
and now i have a giant RTT with gsh which is even bigger than the brief and i love it.
good luck! let us know when you're decided [=.
and before you make a decision, go and try all of them out on you!
