CCP you should make and sell clothing that actually does something in-game. The player base would buy it to get that extra 1% in whatever for example.
CCP would benefit from the isk sink = more plex being sold therefore increase income.
Player base would then benefit as we keep the game alive and more investment would come to Eve Online as our owners continue to make a profit from Eve Online.
So my vote would be to give clothing stats.
You could even give skins stats! Ooo…lets go full commercial Build the skins into different levels of rarity and let market forces go to work. We get cool stats on clothing and ship skins, so they become ‘meaningful’. CCP you get my money/ISK and we all remain happy.
