Realistic mermaid costumes don't have to be expensive or difficult to find. There are several options for putting together an attractive mermaid outfit. Have fun with yours!
A simple, full-length sheath in a light blue or green shade can be the focal point of a realistic mermaid costume.
A flirty layered skirt with ruffles is a practical mermaid dress-up idea, making it possible for you to walk - or even swim - while wearing your costume. You can add an optional tail, for an even more realistic image when mobility isn't a primary concern.
When you sew your own costumes, it's possible to add many interesting touches and decorative features to even the most simple of patterns.
A "train" is a great way to have a realistic mermaid tail while still maintaining a costume design that makes it easy to move around and enjoy yourself.
For a realistic touch, wear jewelry and other accessories crafted from natural shells.
A long flowing wig that combines natural hair color with a blue shade reminiscent of the ocean adds a lovely touch to any mermaid outfit.
