This is a good question. Personally I feel the word "hot" has become nebulous. I have seen it used about girls who are gorgeous and others who are cute. I've come to not know what it means -- it is unspecific. Beautiful, pretty and cute are more understandable but to me the girls with a great attitude, smile and personality are all beautiful.
I would worry less about outer beauty and more about inner beauty. If you are beautiful on the inside people will see it on the outside. I once worked with a very homely woman. However, she dressed better than her feamle colleagues; had perfect makeup; was very capable at her job; friendly; always willing to help; and was self confident without being egotistical. As a result, she looked better than she looked.
