Review: You'll be over the moon with this under the sea costume! - I wore parts of this costume set to Oogie Boogie Bash this year and it truly was a blast! I only wore the head piece, claws and boot covers-- I paired it with a red skirt and top, it was exactly what I was imagining! haha Although I didn't end up wearing the full red bodysuit, chest piece and shell; the costume was great! I would definetly recommend it to someone in a colder environment, as it was suuuper hot with all the layers. So tldr: fun costume, great quality, and super warm -- size small in men's, but worked great for me! hehe
Review: Size up if you're between sizes! - It was a little smaller than I expected, but I was kinda in between sizes anyways and went with the smaller option when I should've bought the bigger one to be safe lol. But it arrived fast, was comfortable and not scratchy for the second I had part of it on, and was pretty solid quality. It also comes with little covers on the Velcro so nothing gets stuck to it before it gets to you. Do recommend even tho I had to return it
