It doesn't suit everyone - Nashville fans will recall when Scarlett cut off her long blonde curls, the resulting elfin cut was (and is) not at all flattering. As with GG, Clare Bowen who plays Scarlett is a very talented performer and really can do whatever the hell she wants with her hair, but I would like it if she went for something else.
I prefer her hair short, but it could be a more flattering cut. I think she has quite fine features and the long hair dominates her face to much, although she does look good when the long hair is tied back or put up. I think she's also been pregnant for quite a chunk of filming (babies in 2014 and 2016 according to Wiki) and there have been times when her face has been fuller and the short hair suited her less.
She seems to be permanently pregnant. I know it's only been twice but she is constantly covered up and made to weary big bulky clothing. It really distracts me because I'm always noticing it! Maybe because she's filming recently after giving birth and theyvwant to cover up her post partum tum?! Just let the woman wear some decent clothes!
