Sofia stands out in no category at all to me. If they wanted a real model, or even a stunning stripper, all they got was mediocre in every way - inside and out.
I hate to judge people on their physical appearance, but this has always been what has struck me with Hoefia. She is definitely not the ugliest person but I have never thought she is this exceptional beauty either - I find just her average looking (in the sense of being average/in the middle of the pack - I wouldn't say she is ugly, but I wouldn't say she is exceptionally pretty either). There are a lot of beautiful models out there if that was what Greaseball really wanted, but.....Hoefia isn't one of them.
Sofia got to where she was because when she was young, she had the combination of having a good body (I don't find her facially beautiful, but I wish I had her body from when she was a bikini/snake model) AND being willing to forgo her all self respect and dignity and pose like a skank for a cheap lads magazine for 14 year old boys to nut to and go on Paradise Hotel and embarrass herself.
If she tried to become a "real" model, she wouldn't have made it because she isn't exceptionally beautiful and she isn't someone with an interesting look that falls into the "unconventional beauty" category. She'd just another one of the many "cute enough" women with a decent body.
