Adorable mermaid dog outfit/costume for little to larger pups!


Ask a question

This listing is for a beautiful mermaid dog costume! Maybe you or your child will be a mermaid this Halloween and needs a sister mermaid!
(Hairbow or flower crown not included, but available at additional cost if desired! Hairbow is additional $4, and/orflower crown is $8 with purchase of costume)

The costume is fully lined and is one piece with adjustable closure at neck and waist. Mermaid shells are embroidered onto bodice with Pearl accents . Mermaid tail is full at bottom and stiffened so it does not look like fabric hanging as some store bought costumes do. The bottom features tulle and irredescent sheer to mimic the look of water!

PLEASE measure your pup prior to ordering! Due to the nature of the sage, all sales are final and it is your responsibility to be sure your pup is safe while wearing any costume/clothing.

This is NOT store sizing!!!! please measure your pet!!! the xs-large are sizes for smaller breeds!

This costume is adjustable slightly which helps, however not all pups are built the same and this is my own sizing scale for smaller/medium build dogs. You must check measurements which are exact. You want your pups to be an inch or two smaller so it’s not snug! My plan is to add a larger breed ( golden retriever size in the future, however it is not available yet!

note: the purple fabric may be the last photo which is slightly different and a little lighter as supplies are constantly changing!
Any questions, please message!
(My model Reese is approximately 8 lbs, a 9 1/2” neck, 14 1/2” girth and 11 1/2” long and is wearing the size small ) because you want the tail to hang longer than body, length should be longer by inches or it will only come to tail of your pet.

**** This is meant to help everyone as I want you to love you costume and I cannot afford the mistakes of inaccurate measurements of people who will not take the time to measure! I do not accept returns due to the nature of the sale. If you ask to return , this will be the response. Costumes are not returnable because they can be stretched out and ruined by trying to fit on a pup that is too big, used for photos or events and then returned, etc. , . I cannot resell costumes that have been sent out..I’m sure you would not want a costume another pup had on. They are still animals and can have fleas, costumes have been covered in fur when returned and so on.. therefore I have to enforce a strict policy. I am not a big box company, I’m just a mom that makes everything herself from her home. Thank you !
