I have three jumbo flap bags, two in caviar and one in lambskin. All three are great bags. If this is your first Chanel flap bag, I would absolutely recommend the jumbo size in caviar which is more durable than lambskin. The size is generous albeit not entirely huge. If you don't carry your whole life with you, the bag should accommodate the daily essentials (wallet, sun glasses, mobile phone, small makeup bag, keys...). I will say that you should be careful to not overfill or "stuff" the bag as this can cause damage to it (trust me it has happened to friends of mine). The bags are really well made and are great to be used as a daily carrier. The jumbo size is not limited, so you shouldn't have a problem finding it. Also, as for colours, I recommend the beige, black or grey as they tend to go with pretty much everything (go with a fun colour for the second bag!) As far as the hardware...gold is much warmer and very classic but silver tends to be younger and a bit more modern (I prefer the gold). Good luck in your search!
