I will always adore the Monogram Canvas however, I do LOVE the Epi Leather. Very Elegant, never gaudy! THe only Epi I own is a red Pochette Accessoires--Great for night!! I love the Red and Mandarin Epi bags!!
Like others were saying..mono is definately a classic..and it just fits certain purses so well. But, IMO I see the mono copied so much more than the Epi, that it makes me want the EPI more. I love the Damier too...whenever I see it, it always reminds me of fine swiss chocolate...I know how wierd that sounds..I don't even think I can explain why..
I also love them both but the monogram has been an LV classic for more than 100 years so it's definetely the classic. On the other hand epi is a far more expensive material (leather) and is much better in rainy weather. IMO....gotta have em both! V
