Question please for those who bought and have in hand the pre-order LV bandouliere and the one that came with MP- does the buckle appear to be secure and stay in place? I had an issue with the Hermes Evelyne GM strap (very similar) in that the web strap would not stay a certain length- it would slip. I ended up having to pin it (which I feel I should not have to do). Hopefully the LV is more secure. It is beautiful and very versatile.
