1. Real, but the seller is charging over retail. I think you're better off going to the McQueen boutique on Bond Street.
2. Fake, not enough pictures.
3. I think this might be real but need to see a close up pic of the tag.
4. This seller sells authentic scarves, but at a huge premium. Again, check out the McQueen boutique.
Also, as an FYI, I'm in the States but the McQueen boutique said they would ship purchases if you're too far away from the store.
Thank you for your help lorihmatthews .And Can you recommend me how much you think it's ok for buying this scarf.Thanks
