My idea of dressed up is different then a lot of peoples
When I dress up I spike my hair up with my bangs hanging down and to the right. black guyliner, tight drawing dead shirt, Blue Jeans with the right knee ripped out, My Etnis, Studded belt Buckeled on my left hip. Touch up my nail polish (black), studded bracelet on my left wrist, braided bracelet on my left wrist, black bandana tied around my right wrist, brass knuckle necklace.
I don't do dress shirt and tie very often. Last time I did was to a concerty and I still had riped jeans and combat boots.
I tend to dress in a way that most people consider 'dressed up' all the time. I've always been more comfortable in dress clothes than say a pair of jeans and tshirt. Even the times I do wear jeans it's usually with a nice dress shirt, sweater vest or some type of sport jacket. So anything in my closet, or rather strewn about somewhere, works for me.
