I had these tactical robes designed specially for me in this war by the Weasleys. (And before you ask, no, they didn't realize it was for me in particular, I just added my specifications and measurements to the Ministry's large order.) Woven into the fabric are multiple shield charms, as well as a few hidden pockets for potions as well as a concealment charm and emergency portkey. Those are a one time only thing, activated if you pull off the labeled button on the inside panel. I hope they fit you well enough. -Cissy
