I bought a mono pochette at my boutique on Saturday. I also bought the long mono strap which my SA attached at the time of purchase. So I decided to change straps and I can't figure out which way the skinny vachetta strap should go. The slit in the leather looks so tiny that I might stretch it out by pushing the gold latch through it, but I don't see any other way to do it. Also, is there a right or wrong side that the gold latch should be on? I looked on lv website and eluxury and they have different ways. Any suggestions?
