In ME2, different outfits for squad members were purely cosmetic (although I did like how the alternate outfits were basically "team colours" XD). In ME3, each outfit gives a 25% boost to one of your squadmate's stats. It's a nice touch to further customize your squad—for example, do you want Kaidan to be able to use powers more often or hit harder with his powers? Give James a boost to his firepower, or further bolster his tankiness?
