Jonny pant issue

So Jonny is tall and skinny. Not rocket science. But the problem this brings is either they are too big around the waist and not long enough or long enough but falling off his butt or too short but fit great around the waist. But we finally found the perfect fit and length for him. Come to find out, it is a very rare size to carry in stores. We went to American Eagle and tried on some pants. He tried on a few pairs to finally decide exactly what size he will need. So we decided to order a pair online and see if they will fit. He was so excited to get them in the mail because he currently has one pair. He got them in the mail and immediately opened them up and tried them on. They fit great except they were about 3 inches too short. It was ridiculous. How could this happen? He tried them on in the store and they fit great. Anyway, we sent them back and ordered the exact same size and hoped that the first one was just sized wrong. He got his second pair in the mail and once again immediately tried them on. We must not have good luck because these were better but still a little short. We will just have to make sure that we don't dry them and try and stretch them out every time we wash them as well. And that is the story of Jonny and how he cannot find pants to fit is body.
