Not true, at all:
1. The Alma was around before the Bolide.
2. It's the other way around. The MK was a copy of the Totally.
3. The SDJ looks nothing like the Birkin, aside from the fact that they are both east-west totes. The SDJ doesn't have the belt wraparound, the three part top flap, etc.
4. The MG isn't a rip off of the Noe. They're both bucket bags, but that's it. What distinguishing design elements do they share?
But I can also sure that your points are wrong. Lol. Ask the ladies at Hermès forum.
