jeans, dark (often black) spaghetti strap tank top, knee high 3 in heeled boots, biker jacket, if the sun dares shine I wear black sunglasses- I have a short (jaw length) layered haircut that apparently looks good and for jewelry? necklace, 4 earrings in each ear, lucky saint bracelet and 4 rings
dress up? black dress, black boots or heels, same jewelry, hairstyle and makeup (I like eyeliner!)
I can't guarentee that all ISTPs dress like this at all- I simply LIKE to wear tank tops and prefer dark colors!
