Definitely get the classic 30 in Gold. Unless you are looking for a small "essentials only" going out bag with a pop of color, the 25 is really small IMO. The 30 is perfect as an everyday bag that will fit wallet, cosmetics case, cell phone, sunnies, keys and even more
Especially if this is going to be your only Birkin....no question....the 30.
