Everyone is different so the only accurate response is depends. Throughout the world different cultures consider various physical characteristics to be either attractive or ugly. We all morph as we grow and some fat ugly kids turn out gorgeous and the reverse is true also. That said everybody is gorgeous to God and their mother and should be to us also.
NO, it does NOT mean you will be ugly as an adult. We all change for the better. I was an unattractive, 6'2", 100 lb. boy in high school. I grew up, gained some muscles, and now am called handsome everywhere I go.
There is no way to answer that darling, everyone is different and develops differently. But I will tell you this, just because someone is pretty now doesn't necessarily mean that they will be when they get older, and just because someone isn't considered 'pretty' now doesn't mean they will become beautiful in adulthood. I was very awkward growing up, and didn't consider myself pretty & of course had ZERO confidence. But when I got older I started taking better care of myself, got into fashions, learned the tricks of make up (by far the best gained knowledge), and most important of all, I found what it was I needed to gain confidence. Once I became comfortable in my own skin and started to carry myself with confidence, people started taking notice. And from there it just kept growing along with the positive feedback I was getting. So I guess to sum up my point, People are going to see you the way you see you, so you have to change the way you look at yourself if you want others too. :) I hope this helps some...
Growing up I always thought I was ugly, and my mother told me ugly ducklings always turn into beautiful swans,after I grew up she said one evening getting me ready for prom, look I told U so! but she always told me I was beautiful
