Hope this is allowed I am not giving the link to the auction just info how to check it out..
I don't know if this will be helpful or not but you might want to check it out anyways. I have seen the fins on ebay auction and they have about a day left. Just type in Monster high lagoona's fins and you should find them..Now her outfit I saw in a MH clothes lot on ebay as well. Type in monster high clothes and it should be the very first one (I just did it to check)or this is the title to it: 25 Piece Monster High Clothes/Access​ories Lot-Pet, Blanket+more in AWESOME shape..I see what looks like her shorts,top and swimsuit. There is 2 days left on it..
