Okay, I NEED HELP, Please! I bought the black/white sig demi a little while back and I LOVE it. But...now that I just won the Legacy Shoulder Zip in black/khaki/ebony...do I NEED both???? Also...a friend of mine has the bl/wh demi and I kinda feel funny carrying it when we are together (which is NOT often) - like we MATCH. Any thoughts??? Are these two bags even CLOSE to being similar? I also just bought the Multi Stripe Demi - TODAY, so would THREE bags that are close in size be too many?!!?
