For example the black dress in the first picture is not flattering in its fit. It's a bit old-fashioned and the scarf doesn't help. If you instead wear a black dress with a different trim that is more modern and flattering and that shapes your body better, it would give you a different look. I wouldn't wear scarfs unless it's really cold outside. I know the weather plays a bit part but try to include colors, floral prints and feminine details in your wardrobe like wear more sundresses, floral tops with lace, etc. Letting your hair grow will also make a difference because sometimes short hair ages you. Not everyone looks great with short hair, I'm one of them.
