It is nice to see someone actually wear a dress to church. At my church most people dress very casual, which is alright, but sometimes it borders on inappropriate. It is nut unusual to see teenage girls in short shorts and tanks with flip flops. I don't think that is very appropriate for church or school either. It is nice that they go, I just wish they didn't dress so skimpy.
As to whether or not my friend Debi should give pointers, the way you all address the situation is a lot more condescending then she was being. If fattie doesn't like it, I am sure she can tell her all by herself. She is a big girl, and people don't need to be rude and mean to Debi under the disguise of sticking up for fattie.
