Is it normal that i've been asked this in the street three times?

Pics?

I have a feeling you're not ugly at all. And besides, you don't have to feel threatened, there are all these pretty girls, but they want you! You obviously have a natural beauty that most people don't possess. You should be empowered.

Lucky you. I think you should go for it, it's easy money to be honest.

Can you show us some pictures of you?

The era of beautiful models is over now what agencies want is weird faces and beautiful body.

Go for it no harm in trying right?

Standards for beauty in modeling and standards for beauty in the real world are sometimes vastly different.

Some models are considered highly desirable by agents due to their versatility. Their figure can be used to model diverse types of fashions, their face can appropriately accommodate many different types of makeup styles and their bone structure and pigmentation can accommodate different hair styles and hair colors.

The "beauty" you see in many magazines is often the result of skilled cosmetic design, computer editing, lighting, background ambiance and so on more so than the actual natural looks of the model themselves. A model is a pallet for artists to utilize and often the trick is to find the right pallet. Some of them are naturally pretty looking packages without the artists help and some of them are chosen because they have the potential to jive very well with the will of the artist. Not to mention, as dappled said, your look might be the next big thing. Fashion designers are always looking for something to make their designs stand out, even if it is looking for unique looking models to model their designs.

Really, models are just advertisers.

If you want to, I would say, contact the agencies and do some research on them to ensure that they are legit (don't just go to their website, look everywhere) but if not, at least accept the compliment ;)

Pretty normal, my girlfriend was scouted this way. I find most models ugly.

Some modelling agencies do scout girls on the street. I remember quite a few top models saying that is how they were approached. Often the look they are going for is quite striking. What you may see as ugly, they might think of as the next big thing.

How tall are you, by the way? If you're under about 5'9" then be wary. But if you are tall, they just might be genuine. Either way, be careful, and don't get yourself into vulnerable situations.
