In my experience , the registration failing is because they ' ve rotated off your guest list , so you ' re basically screwed either way . They ' re already gone . I don ' t know if there ' s a way to keep the guest list from updating without going offline , but that ' d be annoying to do every time you want to walk around your plaza and talk to people , and pointless if they ' ve already left . As for it ' s not easy to order this item , I don ' t know what is either . I ' d thought it was post Elite 4 stuff , but if you haven ' t been able to order items you ' ve already seen I don ' t know . I have a question of my own . how do you get specific pieces of clothing ? A friend and I tried swapping outfits but we couldn ' t seem to get anything besides offering each other shirts . Can each person only offer one clothing slot ? It doesn ' t seem to change per day or if you go offline . And I ' ve never seen anyone offer glasses or accessories , only shirts , pants , bags , and shoes . Since you can offer specific plaza stalls by placing them correctly I ' d be surprised if there wasn ' t some way to offer a specific piece of clothing .
