I have sold some bags and saved some money and am plotting my next addition to my small collection. Due to a number of of upcoming expenses like taking more grad classes, this will be my last LV purchase for quite awhile so I want to choose wisely. I am debating between a Totally MM in mono or the new DE Portobello. I want a comfortable bag with a zipper to use while traveling and for weekends. I currently own a mono Artsy MM, a DE Neverfull MM, and a DE Speedy 25. I love the styling of the Portobello, but I am worried it is too much like the Artsy to justify the purchase given the small size of my collection. Also, the fact that it costs $400 more is not insignificant. If I go with the Totally, I will use the savings (along with selling my Speedy 25) to fund a DE Speedy 30. Opinions would be appreciated.
