I'm trying to decide on a black Birkin, size 28 or 30. Which do you consider a more "everyday" bag? I like the Birkin, but I like that the HAC is the ORIGINAL Hermes design (which was later modified to the Birkin). I'm small, 5'4" and about 120 (last time I checked, I don't like to weigh myself often ) If you could only get one , which would you prefer? Why? Thanks in advance for your help with this ever-so-important decision!!
