I have misplaced my thieves guild armour and this is an issue as i need to hand it into tonilia to be upgraded to allow me to get the guild master armour so i can complete the thieves guild questline and get the trophy. Anyone any idea on how to reacquire the armour? i think i gave it to faendal but i cannot find him anywhere in Riverwood and i have checked Whiterun hall of the dead and he is not there so i am clueless as to where he is. he isn't my current follower as i have Lydia following me. Any help/suggestions?
There should be spare pieces of Thieves Guild armor in the Cistern, unless you've misplaced/sold those too. Start your search in the room with all the lock-picking-practice-chests.
