This is REALLY hard - hmmm, most of my limited editions pieces I love to death, but aren't really that practical. I guess I would keep my pomme vernis Houston. It's a stunner and I could use it almost every day.
Only one??? A classic...my mono speedy 30 so I can carry it around and show off, but my other choice and one that I don't have (yet) would be an old trunk. Love seeing them on Ebay! It would be on display in my apt!
It would be between my first ever LV the Black MC Speedy (it was a gift from my dad) or my only LE piece the Cerises Speedy (which also means a lot to me because I bought it with my own money)
