The Froppy costume is a full bodysuit with all the accessories. This is really cool. It comes with the shoe covers, straps, belt, and gloves. the only things missing are the wig and goggles.
You can find the Froppy Tsuyu Asui at Amazon here.
I did find a good quality Froppy wig at Amazon here.
If you’re having trouble finding the goggles, check out LelegacyCrafting on Etsy. They make really good cosplay props. You can get the goggles here.
