buying from Hermes stores don't guarantee authenticity (certain stores that is). My friend bought a birkin from Bangkok Hermes, and brought it to Singapore Hermes as she had a problem with it. They told her it was a fake ! They kept her bag as they wanted to investigate the case.
Are you serious??!? What is the world coming to? We can even get fakes from H stores? I am still planning to go Bangkok around June and perhaps buy some stuffs from their H, thou I am not looking at Birkin and Kelly after reading in tPF that it's impossible for tourists to get B and K in Bangkok H.
Do keep us updated on your friend's case!
