I loved Wei and Wing's pj's too! Frankly, all the sleep attire in this show is awesome. The airbabies and their pj's in the fourth season (in Zaofu, the place of pj's, apparently) was very cute and we also got a nice, beautiful shot of tired-and-grumpy-Huan. And the bending bro's in nothing but boxers and tee's is never not a welcomed sight in my book. Hehe. Korra's sweatpants and Asami's luxurious looks were very welcomed, too.
