Accesorise. Jazz the blazer up with feminine things. Badges, broaches, extra materials etc.
Wear feminine but fitting neck wear like a neck scarf or necklace. Try and layer what you're wearing underneath instead of a black t-shirt. Wear a t-shirt, with some form of short sleeved shirt, then the blazer. Adds a bit more... interest to the outfit and normally a bit more femininity.

Try and buy a blazer for women too... Mens won't fit properly, womens are generally fitted so they expose your womanly figure which instantly makes it a lot more feminine.

Also, try to avoid a t shirt that comes right up to your neck. Get something that hangs a little lower, show a bit of skin.

I know this isn't very 'rocky' but this is the kind of blazer I mean: http://images.asos.com/inv/r/7/221/5...y/image1xl.jpg Search boyfriend blazer in Google.
