Scars?

Okay I need help its coming in to summer for me and i have like a averagely big scar on my leg and its like purple?? anyway I haven't a clue how to cover it up... Anyone??

If the wound is healed,isn't infected, then I sugest tights or I know this kinda weird but powder like conselor...I do have scars on my legs too but I normally wear tights year round so...that's all I can say I'm sorry

Yeah tights are like my best friend but i have this school trip coming up which my mother is attending and its at this water park.. So swimming and I can't cover them up..

If the scar is above the knee isuggest shorts there are shorts that reach the knee also ithink there is waterproof concelor or am i thimking of mascara?? Anyways i hope the best oh btw don't email me if you have a problem cause my phone doesn't like sending emails here but i can post here if you need me best wishes and hopes
