hi everyone, I recently bought a medium lady Dior with a thin leather strap in Europe. When I got home to the US, I took my bag out to try it and and use when I was attaching the shoulder straps, I noticed the clasps stay open and don't close themselves like regular straps do. I have to push to clasp for it to close all the way. Is this normal of Dior straps? When I tried on the bag in store, the SA attached the strap for me, so I'm not sure. Is is a defective clasp? Will I have issues exchanging it in the US? Thank you for the help!
