Cosplay feedback?

Hi, my name is Leah and my friends and I want to do a five-man full team League of Legends cosplay. Recently, I've been playing support a lot so they want me to cosplay a support champion. However, I cannot decide who to be. I've narrowed it down to a few options but I was looking to get some feedback from the League community in attempts to help me decide. Also, it is worth mentioning that the cosplay has to be of a skin.

Right now, I'm looking at

Star Guardian Lux Forecast Janna Armor of the Fifth Age Taric A Thresh skin. Not sure which one and also it would be a sexy Thresh,not a normal Thresh cosplay or a Lulu skin. Maybe Winter Wonder Lulu, Wicked Lulu, or Bittersweet Lulu.

Any and all feedback is welcomed.
