I've been reading your messages and understand your dilemma.
I was thinking in what I would do.. It depends actually on how many bags you already have. I mean, if you don't have many and you are going to buy a nice clutch or bag for your wedding day anyway, it might as well be a chanel! It will last you a lifetime and like somebody said before it gives extra sentimental (and historical value
It will give just the extra touch to your outfit, so if you will buy it anyway, might as well do it before your wedding..
Also, I'm not sure what the habits in singapore are, but maybe you can ask it for a weddingpresent from your loved ones?
Explain the situation to your fiancee and if he still cannot imagine it in one way or anther, stop thinking about chanel for a while and start thinking in your wedding/decorating your new apartment..
Let jus know what you will decide! (I'm secretly hoping everything will work out and you will have a gorgious white wedding with a gorgious white chanel in your hands, but then again, I'm a sucker for romantic images
)
