Your first level of self-defense is what you decide to put on.
What kind of attention are you seeking or not seeking?
Can you move in it?
Can you run in it?
Can you twist and turn in it?
Where are you going?
Is it day time or night time?
Are you carrying anything?
Shoes? Sneakers? High Heels? Flip-Flops?
Hey, to each his own or her own. It doesn't matter to me what you choose to wear, or what kind of an image you want to put out there. However, as a student of the martial arts, you can't be naive about what may come your way and what you may have to do about it.
