I have the mm size. I use SLGs and nothing is ever loose in my bag ever, unless I have a small bag and need to remove my keys from my key cles and just have my keys loose. It's not super tight in the bag, but once I take out my phone, or my little leather pouch, or Chanel Mirror, etc, I have to somewhat arrange it back in. Using my pouches takes up more space. I'm somewhat extra with all I do. Lol. I'm my worst enemy at times. LolDo u have the pm or the mm size?
