Please help me decide, Damier Speedy 30 or Duomo. (ro)

Go for the Duomo! It's gorgeous and definately worth the money...
I agree they look a bit alike, but IRL they are completely different. Speedy is saggy and casual, Duomo is classic and chic.
 
I have both the Duomo and Damier Speedy but in the 25 size & I LOVE both! if price is a consideration, I'd say go for the Speedy... but if not then the Duomo is a great choice... very classy & it's great for work and as a everyday casual bag I reckon... depends on what you wear really... you could always get the Speedy later on coz it's a classic after all:P ... but with the Duomo it may be discontinued after a while...

keep us posted! and good luck with your decision!
