This listing is for a pair of custom Siren's Grotto seashells perfect for any mermaid costume! Each pair is unique and made to order with your color and notion specifications, and my designer touch!

Shells are real, genuine scallop sea shells, treated and painted in any color or color scheme you wish. They come with holes drilled into each shell (4) and can either be worn bikini-style with ribbon or string, can be attached to a bra (via velcro) or strong elastic, or can be worn with both a bra and ribbon. The ribbon/bra/elastic is not automatically provided, but can be added on for an additional fee if requested. *Listing is for the shells only. Since different body types are flattered in different ways, it is up to you to decide how you want to wear them. It is not a finished bra, but seashells ready to be placed on one, or worn on their own with ribbon.


Price in the listing is for 2 seashells with holes drilled in each, custom painted to your specifications in any color or color scheme you wish. FIRST PHOTO IN THIS LISTING IS AN EXAMPLE OF WHAT YOU WILL RECEIVE IF YOU DO NOT ORDER ANY ADDITIONAL ADD-ONS. Shells are sealed and treated. Listing price is for the basic shell option. Should you want to add on notions as shown in some of the photos, such as swarovski crystals, starfish, bicone crystals, freshwater pearls and pearl strands, faux pearls, glittery sea grass, etc. I will speak with you about what you want added, and listing price will act as a deposit. When your shells are finished, I will post a custom listing for you with your balance and photos of your exact shells to approve.


Size of shells is approx. 5-6 inches. Covers A cup little to no cleavage, a B cup with some cleavage, and a C cup with lots of cleavage. (I am the model in the photos, and I am an A/B cup. The purple shells in the photos are not attached to a bra, and only are attached via elastic. The pink and white shells are attached to a bra. If you are larger than a C cup, contact me for options on how best to wear your shells).


You can contact me directly if you would like to add on any additional items to your purchase and I will price quote you. Items that can be added in with your order:

strapless bra in your size (colors available are white, nude and black)
heavy duty velcro
nude pasties (I always wear them underneath for extra safety!)
additional holes drilled into shells (no extra charge)
*You are responsible for assembly, as it is difficult to do without knowing the wearer's exact size/shape.


Please note that seashells are real, and thus slightly on the heavy side. Shells are not automatically treated for underwater use. Please specify if you plan to swim in them so I can seal them with the right sealant. The sealant for underwater use changes the look slightly, so I refrain from using it unless absolutely necessary. Additional $15 USD for waterproof sealing.


Shells shipping within the USA are shipped out via my preferred shipping vendor, UPS. Shells shipping outside the USA are shipped out USPS. If you would like to use a different method please contact me.


Photos in listing are only examples of what the shells can look like, depending on your preferences and design choices. Listing is for your own custom pair, made just for you! Not the exact shells in the photos.


Great for mermaid photo shoots, halloween costumes, live mermaid events, performances, beach looks and of course prancing around the house pretending you're a magical siren of the sea!
