Like others have said and I must agree...both look really nice on you. But for your first...I would suggest the Speedy. Good Luck making your decision.
I voted for the Speedy as it seems that you carry your bags in more of a hand-held position. If you can, I would keep both though as I love the Neverfull as well. Both look gorgeous on you.
they both look great on you, but since the mono speedy is always available - no matter where you are, might as well keep the neverfull & get the speedy later.
I voted Speedy. You can dress it up or down and it will go with everything, whereas the Neverfull is more casual. The Speedy also looks really nice on you.
