I love the squarish looks to these bags, but wondering which one is better. I saw a woman with i think the triana and it looked so fab, like the epi pont-neuf. i love that the quality and design of the bag can make it go with a luxurious or casual outfit. can anyone tell me the differences / similarities of the bags, other than the square shape! i can't download the elux/vuitton website photos, so please let me know your opinons! thanks.
