The knit fabric of this is PLUSH and the details and workmanship are both great. I got a 3x because I was worried about having room in the bust and booty, and I could DEFINITELY have gotten a 2x and still had a great fit (for my fellow fat girls: I'm 5'7" 260# with a mostly hourglass shape and a bit of an apron belly), but wearing this oversized still looks great and feels comfy. The larger size/fit mostly means the sleeves extend past my wrist (like we all did in the 2000s anyway). I got a ton of compliments from my remote work coworkers, who only saw me from the chest up! And none of them are nerds! It looks good and is fully stealth mode for profesh settings, which is fun.
If you ever want to make a duster version that looks like Spock's robes from The Voyage Home I would almost certainly get that, too ;)
