Disney Little Mermaid Flounder Pet Costume for Dogs or Cats - Large

In this review of the Disney Little Mermaid Flounder pet costume, the bottom line is simple: it is a charming, officially licensed outfit best suited for owners who want a safe, recognizable character look for photos and short wear. The costume delivers on presentation and build quality, and Rubies' longstanding reputation offers reassurance that the item is authentic and safety-tested. Fit is the main practical consideration - the company emphasizes consulting the Rubies pet size chart and instructional video because the costume's style and sizing can affect how it sits on different pets.

Key Features

• Officially licensed: The costume is marked by the trademark on packaging and labels to confirm an authentic, safety-tested Disney item.
• Designed for photos: The bright Flounder design creates playful, high-impact photo opportunities to showcase a pet's personality.
• Size guidance provided: Rubies recommends using their pet size chart and sizing instruction video so owners can choose a more accurate fit than selecting by breed alone.
• Family-owned maker: Rubies Costume Company has produced costumes since 1950, which supports consistent quality control and heritage craftsmanship.
• Easy to wear for short periods: The costume's simple construction makes it suitable for brief events, social media photos, and group costume themes.

Who It's For

This costume is aimed at pet owners who want an officially licensed Disney look for special occasions, themed photos, or brief dress-up events. It works well for owners who value authentic, safety-tested products and who will check the Rubies sizing guide to reduce fit surprises.

Owners seeking an everyday wearable pet garment or those who need a highly adjustable fit for a very small or very large animal may want to look elsewhere, since the costume's style and limited adjustability mean sizing precision matters.
