Scars on leg

This year when i went to the snow, i injured my legs, which resulted in huge blisters on my shins. Now they are huge ugly dark marks on my skin, I’ve tried Vit E cream, but it doesn’t seem to be fading. Well that’s not really the problem. The problem is that I’ve got a family wedding to attend in a couple of weeks and the dress I’m wearing shows the scars very well. I don’t know what to do to cover the scars up and i dislike wearing stockings (as recommended by someone). What can i do???
