Well actually YES! (The braces at any rate but a shite pair of glasses can do a power of no good too.)
I'm sorry but I remember school and yeah we (I had braces) were all looking quite ugly thanks to them.
People are shallow. I'd reckon anyone who fancies that Ugly Betty girl is responding to the lightning wit, talents, etc. of her contrived personality and not to her looks.
Also, the actress is called 'America' apparently so she should be shot immediately.
