In my opinion tomb raider underworld is much better than tomb raider legend because you learn alot more about Lara in this one especcially because her devotion to finding her mother is much more...
It depends where you are. Please include where you are in the tomb x
Yes :)
In Tomb Raider Legend you get the outfits by getting all the rewards in the levels and in her house
To get outfits on tomb raider legend you have to collect hidden rewards, complete time trial and levels to unlock them.
