Definitely PRADA. I seen it at the boutique a couple of weeks ago. I don't think there's a triangle, but the logo is there. It says prada in gold writing.
OMG!! This is the same bag i saw on Lucy lui a week ago in LA!!!! It is stunning in real life and the size is similar to medium balenciaga but the hardware is more retro...It is a beauuuutiful bag. The leather is stunning
