Definitely do not make the basic free gee-suit the most sellable one... If you know what i mean. Out of the v2 concepts, the basic is the one that will account for 99% of income. Throwing it away is shooting yourself in the foot. I strongly advise you look at Vindictus' inner armor market. It partially carries the game financially when every time a player make a character, they want to buy something to look nicer than tidy white.



Make the basic suit and outfit conservative and boring. The marketing material can feature premium suit all the time. It's what every successful game does (unless it's a customization feature scene).



The smarter you are with building an easy to maintain cosmetic economy, the more budget and freedom you will get at developing good gameplay.



Also metro and manly cosmetic will sell too. Funny cosmetic as well. Not as much as the #1, but they help bring diversity and add up!
