"Surprising Reason Men Don't Call Women Back
#2.
Look like a woman. At work, conservative and structured clothing allows you to be taken seriously, but it's not exactly sensual by candlelight. Don't go straight from work in your power suit to meet him for dinner; rather, change into something soft and flirty. And try growing your hair longer: men told me that shoulder-length hair (or longer) is more feminine. Sure, you're a strong and capable woman, but think Scarlett O'Hara not Hillary Clinton."
It is interesting that longer hair is not associated with being conservative.
The other reasons given are also relating to femininity and showing the softer side.
