so far for my space suit I got a deepseeker helmet and a shocktroop suit which I think matches well enough, I like the helmet a lot
for regular apparel I got some security outfits luckily I had enough of them to give one to each of my crew so they all match while on the ship, for suits I got most of them pirate suits
My favourite space suit so far is the one you get near the end of the vanguard quest line. Makes me look like a badass UC marine.
