Hi, I'm very new to Chanel and will be purchasing my very first Chanel bag! Of course, I'm thinking of getting the Classic Caviar Flap (in black and gold) but am indecisive on which size. I'm about 5'4, petite frame. Will the large be overwhelming for me? Is the medium size more of an evening bag? I'd like to use it for day and night, casual and dressy and hopefully to have a size that will 'grow old' with me... so please let me know which size you think is best! Also, I will be visiting New York in October. Is it cheaper to buy Chanel in NY or should I just buy it here in Toronto? Can someone please post the price of a med and a large Classic Flap in U.S and Cdn $? Thanks for your help!!
