I have to disagree. There is a place for the half tuck, just depends on your personal style. When I wear a very blousy top, which I did over the weekend, and I found it was too voluminous, I tucked in just the front, kind of bloused it over the waist band, left the back out, and I believed it was a better look on me. I also received several compliments on the top and look.
I've always believed anybody could wear anything as long as they "owned it" and felt good. What I wear may not be what one of my cousin wears, and vice versa. However, I would never look at her and tell her she looked sloppy because she was wearing something I wouldn't wear. Very judgmental in my opinion.
