Karman,
For me, it seemed like this year was a strange exception in LV. This past spring and summer they had put out so many different and exciting bags that appealed to me, mostly limited editions, that I really couldn't decide what to get, but I now have some nice bags that I know I will definitely keep in my collection in the future. Mono is nice, but it will always be around, KWIM? So that is why I had more interest in the LEs.
Of course, now that I have my Mirage Speedy and My Limelight Clutch, the obsession has pretty much subsided....it doesn't mean that I am tired of the brand, it's just that now I can actually sit back and enjoy the things that I do have. I don't keep a "wish list" because it seems like once you get something off that list, it's onto the next item, without really getting to enjoy what you've acquired....Like, I know I want the mono petite Noé, and the MC Aurelia MM, but I am ok with waiting until I return to France next June to buy them there, and now, I can look over my collection and enjoy what I have.
As for other brands......well......I had several bags from other designers, and I have pretty much sold every one of them, with the exception of an all pebble leather Dior Saddlebag, and even this one gets me thinking....."next!"
I've always loved LV first, and for me, if I buy another designer, I get really tired of it later, because it's not an LV !!!
Look at your collection......it's simply GORGEOUS !!! You have things others would DIE to have......and look over each bag, think of how special each one is to you....I know you're tiring of the mono pattern. Did you ever think that maybe it's time for you to step up to just collecting the runways or Limited LVs?
