So after doing the questline for the thieves guild, and the 5 hours of b.s. (raise the guilds renown) quests, I was dubbed guild master but to complete that quest, I have to have my guild armor (sold it roughly 90in game hours ago). If its a quest item, why the moon sugar was it sellable? I have 4 achieves I need. One glitched out, other two I have almost done, but this fourth one? I really have to restart a character and do the entire thieves guild quest line again (12ish exhausting hours) for this achieve?... I enjoy this game, but ffs bethesda, please patch these problems. At the very least make it so that when you get the armor they say "hold onto it. If we ever make you guild master, you HAVE to have those".

Oh n I've been looking for the vendor I sold them to hoping they'd still have them... Pretty sure I sold them to the redgaurd who improves the armor, and I can't access her merchant inventory cause all she says is "its time to improve, oh you don't have it? Haha fugger!"

... Times like this I want to slap kittens... In the face... With a nail board... With hot sauce on the nails... Yeahhhhh

There's an extra set near a bed and in the Lockpicking room of the Thieves Guild.

The armor pieces are actually scattered throughout the tavern. In that Archery Room., the chest piece is above the "closet" the hood, boots, glove are in the same room. some are in the shelves of that "closet", some are on top of those barrels. If you have trouble, go to UESP or the Skyrim Wiki.

This... if you leave the Cistern for a while, it will eventually respawns when you return (not to mention the chests refill and other goodies appear).

I was mistaken, the lockpicking room. but isn't there also an archery practicing range there?

yep.

Why do you need Thieves Guild Armor for this part?

Omfg thank you guys so much. I mean I thought of pickpocketing other thieves to see if they had the wardrobe. Checked all chests which I looted long ago when working on lockpicking. Even murdered everyone to see if anyone even had a set and then back loaded. Didn't think to check the out of furniture items. But thanks to this thread I got a set, got my gm armor, 30 seconds later got my achieve. Only one I need now is the deadric one, which I guess I can't get since I returned the skeleton key... Sad face

You don't need it.
