Okay we know that Tataru has some talent for weaving (probably more than the player given that she also design the cloths in question) and we also know that she commissioned a set of mammots based on the Scions, herself and the Carbuncles.

But the latter group has a peculiar detail. According to the minion guide she created the shell of the carby minions. This detail has me wondering if Tataru Taru knew of her prowess with the needle, since she didn't make any outfits before Heavensward (that we know of)
