Platinum Seal Classic 1 Attachable

SHOWN: Platinum Seal Classic 1 breast forms, size 7, with Platinum Seal storage box

Our Platinum Seal Classic 1 attachable breast forms are perfect for the girl looking for the most versatility, the softest silicone, and natural looking nipples!
  • Flat back design is perfect for giving you the most projection
  • Softer than SuperSoft silicone gives you natural movement and the most bounce
  • Soft, non-shiny matte skin feels like cashmere
  • Realistic, textured nipples & areolas for the ultimate realistic look
  • Double-strength membrane on the back is durable enough to attach and go braless* but can also be worn with your favorite bras

Our luxurious Platinum Seal Classic 1 breast forms feature a double-strength membrane on the back of the breast form, making them durable enough for attaching and are even guaranteed to go braless!* They're also great to wear with your favourite bras.

Each breast form is designed to fit the left or right side of your body. There is a small wing that is designed to go towards your underarm, helping to create the illusion of natural tissue and make your shoulders appear smaller and more feminine.

Why we love our Platinum Seal Classic 1 breast forms
  • Designed to let you go braless*
    • Guaranteed to go braless* when used with our medical-grade Double-Sided Tapes
    • Includes a FREE Double-Sided Tape Kit that's easy to use to go braless, and is easy to remove from your body and the breast forms
      FREE Double-Sided Tape Kit includes 24 Double-Sided Tapes and 12 Skin Tac Wipes, and is valued at £20.04 [Incl. VAT]
  • Fits great in all of your favorite pocketed and full coverage bras
    • Can be worn in a bra, attached with a bra, or just worn braless for any look, any time!

    • Curved bottom shape works well with underwire bras
      Please note: A damaged bra can cause the underwire to move out of place and possibly puncture your breast forms. Although our Platinum Seal Classic 1 breast forms work well with these bras, please be careful while wearing them with an underwire bra to help avoid possible damage to your breast forms.

All Platinum Seal, Gold Seal, and Silver Seal Breast Forms are guaranteed against manufacturer's defects for one year from date of purchase.

  • Platinum Seal, Gold Seal, and Silver Seal Breast Forms are guaranteed against failure of the Double-Strength Membrane on the back side of the forms caused by double-sided adhesive tapes manufactured for and sold by The Breast Form Store and its affiliates. Staysput Adhesive is also covered in this guarantee, however the use of any other tape or attachment method will void the guarantee.*
  • Platinum Seal, Gold Seal, and Silver Seal Breast Forms are not guaranteed against abuse, punctures by sharp objects, excessive pressure being placed on them, excessive heat, or other actions that would not be consistent with normal wearing of a breast prosthesis.

*IMPORTANT: While many of our clients are using other medical grade adhesives, adhesive sprays, medical grade tapes and removers with success, we regret that we cannot provide a guarantee if they are used. There are so many formulations of adhesives and removers that that The Breast Form Store is unable to test and guarantee them all. If you are considering any other method of attaching the breast forms than the products we provide, please do so with caution.


All claims under this guarantee require the return of the breast forms to The Breast Form Store. Forms cannot be returned without a Return Authorisation Number. Please call us for an authorisation number. Shipping charges are at the expense of the buyer. The guarantee only extends to the initial pair of breast forms purchased and not to any replacement forms issued to previous charges.

Please note: A very safe and easy adhesive remover is baby oil. It is safe to use with both liquid adhesives and double-sided tapes, as that baby oil neutralises most adhesives. Apply to edges of tapes and slowly remove tapes as adhesive is neutralised.
