This Mermaid Tail will transform any little girl into a sea sirene!

Made from stretch Lycra in a shimmering metallic blue with a three-layer Tulle and Organza fin in aqua and blue with glittering waterdrop sparkles. The tail also features a back fin made from the blue metallic Lycra.

.... and don't worry, the tail is cut in a way that walking in it won't be a problem.

Please choose your size above.
Sizes stated correspond to the age of the child. If you are unsure about your little Mermaids size or need something special, just send me a message.

Each tail is made to order and takes about one week to make.

Frequently asked questions about AtelierSpatz

All costumes are/can be made to measure. Sizing options within each listing refer to standard measures within each age group and have been tried and tested on actual children. They also work as a guide to estimate the amount of fabric needed to make the garment based on the standard measurements within each age group.

Please get in touch to provide the measurement of you child unless you want the garment to be made in standard measurements.
Nothing is more enjoyable than creating something for the very first time. Please don't hesitate to be in touch to commission a custom order of a garment or accessory.
I recommend all my costumes to be dry cleaned.

Some items can be spot cleaned, please contact me if you need instructions.

Pirates: Shirts and Trousers are washable at 30C.

Bird Capes: They can be ironed. However, please be very careful and iron them only from the wrong side (the inside of the cape). If the cape gets creased during storage, hang it out (possibly in a steamy bathroom), then iron at low temperatures from the wrong side.

Superheroes: The cape and cuffs are made from pure cotton to ensure safety (low flammability) and durability for the kids. They do crease. You can iron them, but don't use steam or directly contact the metallic fabric.

Clown Collars: Those made from pure satin can be washed as delicates at 30C.
