I agree, the clothes are not becoming on her.
I also think maybe the clothes don’t look so good on her because she got too skinny (at least it looks that way to me). She looked better when she had more meat on her bones. You can tell she works out a lot but she just looks a little emaciated. When she first came on the show, I seem to remember she had a shape. I’m not criticizing her, just making an observation as I really like the character (most times anyway).
