I main 
and really just the role of support in it's entirety. I love almost every skin that league has to offer and am always trying to get an entire team together with matching skins. I was just wondering though, which matching set of skins is most viable for gameplay as well as fashion? Haha
Thank you in advanced guys!

The "Classic" line is 100% viable.
Star Guardian is the most tilting team. So bright and amazing!!
I think a lot of the Worlds champions skin lines work.
If you want to use Sona:
Christmas skins.
Lot's of them too, so you could swap people out if you wanted.
PROJECT is probably the most viable excluding E-sports team skins (TPA, SKT, Fnatic, etc.)
Project has a lot of viability if you go Flora/Ekko/Katarina/Ashe/Leona and has good team fight, ok wave clear, engage/disengage.
Blood Moon could do some work if Khalistan weren't so bad right now/if you can make ADC Kennen work.
I think blood moon could do ok with

Arcade, Pentakill and Snowdown is the way to go

I wouldn't go Blood Moon if I were you. Kalista is really bad right now, and nobody is calling for her to be buffed because they remember her pre-nerfs. She needs a rework.
You obviously can make a real easy premade team using esports skins like someone else mentioned as well, especially SKT T1.
You could even get more general and pick skins that have demonic, pirate, police, fire, or winter theme for example. They would still match, but they wouldn't be from the same line.
