The numerous questions about bag sizing has me wondering if most of us buy the same size in a certain style ( always a 35 in the Birkin...or always a 28 in a Kelly ) OR do you buy the differing sizes and leathers to suit the occasions you use the bags? I have been looking for a slightly smaller Kelly to wear when I don't want to carry the kitchen sink with me, but still have enough room for wallet, keys, glasses....for luncheon or out in the evening. I find that my 32 Kellys are just a little too much for these occasions, and sometimes, my 28 Kelly is too. So, I have been searching for a 25 Kelly. I still need my 35 and 32 for work, and my 28 to run out to the grocery store The HAC 32 is a great work bag with an *edge* and the 30 Birkin is perfect on days when I don't have as much to carry. Both have a different feel and fill different needs on different days. And, my black mou Bolide 32 is the most perfect all 'round style when I need the essentials, but don't have to carry a lot. I've considered the 37 Bolide to do the same thing, but hold just a little more. So, I was wondering if many of you think this way when you're considering a piece or do you generally stay with one specific size or style??
