I think most of the Kgirls from the stables are of decent standard. If not the stables won't be around.
But if you too have to manage expectations of how the girl looks in picture and in real life. Some of the photos are very obviously photoshopped, so don't choose those girls if it bothers you that much. Choose girls that show real selfie photos. Like Min from KBS, or Raina from Sensations.
Personally I tried Raina from Sensations and she was better than 100% of the selfie photo and with a really perfect body. She'll be back in the summer. Can't wait for RTF

We gotta shop wisely as well.
