ugh... what a toughie cuz there's different elements that I love about each year... but I'd have to say 2005 as the all around best - GREAT variation of colours (something for everybody!) although I may be biased as I love the brights... and great leather.
Although hmm.. now that I think of it.. if we were talking more about pastel colours then 2004 was another great year filled with GREAT variation in colours and fantabulous leather...
Ok - I changed my mind and vote for 2004 even tho my gut originally said 2005. 2004 for great colours, great leather, AND the variety in hardware!! You could get the pewter or the brass depending on the season.
'02 baby! 2 seasons of Flat Brass and one of Pewter Hardware on luscious suede. The original Flat Hobo is super cool IMO, it's strap is long enough I can wear it messenger-style and the curved top opening is lovely.
