I agree with both of these comments. But I am a minimalist.
Personally, the mini and the chain around are my least faves. However, I also think that you need to ask yourself some deeper questions:
1. What is your ultimate goal regarding your Chanel collection? (quantity, to own specific pieces, etc.)
2. Why did you buy each of these bags in the first place? (impulse, lifestyle need, HG, etc.)
3. Is your objective to sell a couple of your current bags to fund your dream red bag?
Chanel just raised their prices. So I'd hate to see you let go of something that you truly LOVE and really USE, only to be subjected to a higher price tag and a greater sacrifice from your current collection. So, your answers to the above may help you to determine what steps to take next.
Good luck, and God bless!
