Costumes are usually fairly steep. I like Oscar one. It's clearly the best. The Bert and Ernie ones are fairly good too. Cookie and Elmo seem factory standard without much love, but okay.
I posted about the Muppet ones a while back. I got to see the actual catalog. The Miss Piggy one is that cheesy type of costume girls wear to look sexy, but it really is just dressing like a stripper. The gloves aren't even nearly correct. Just an all-around fail from me.
None of the Muppet Show costumes are that attractive to me, but it's good to see the characters making the rounds in this popular medium. Fozzie's the best, but I hope the swap the black pants for orange ones. The rubber masks are strange and should look better. Fozzie's is the closest. Kermit is okay, but why not a nekkid version? Animal is okay. He's hairy so he's a difficult sculpt. They really tried with this one. Gonzo, well. He just looks ugly. I'd rather had fuzzy Oscar-like translations if the likenesses were going to be this poor. Fuzzy costumes just seem more comforatble.
Still, this isn't for me becuase I don't do costumes so it's hard for me to judge. It's nice to see the Muppets around.
