I gained a little amount of space since changing to male Miqo'te since the Shisui gear looks rubbish on my character now :P.

Still Armoury Chest I find it harder to work with then Inventory. An increase to Retainer Inventory would really be nice, I would be able to free up so much space if I could dump more Glamour onto my Glamour retainer. Hopefully the Glamour Book will come out soon. It should solve quite a few inventory problems.
