Hello! This is my first Chanel! It's the XL Red (I don't know the exact name) GST! A gorgeous red. I got it preloved in like new condition. I love the size and it's surprising very light. I was a bit concerned with the handles because I've read that they won't stay on your shoulder. All my bags are very slouchy so this is my first very structured bag. Will it lose its shape over time? I also love the Celine Phantom In Tan. Should I keep my first Chanel or return it for the Celine? Please tell me what you think.
