Since the clothes she makes can protect the wearer from passing through the barriers that protect the Royal Palace, her scale has to do with the balance of souls between the human and spiritual world (and the barrier between them) and she effortlessly entered into Mayuri´s lab (when Mayuri asked her how, she said she simply placed her hands on its door and it opened by itself -"the lock was easier to open than the last time I was there"-, I'm thinking it probably had a barrier, a trap or was really difficult to open or something), I'm sure she has something for barriers so my guess is that she created the Shakonmaku.
