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
  • 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!
    • Fully fills your bra; no empty side or puckered top!
    • 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.

How to use this fitting chart

Intersect your bra band size (the number) with the cup size you want to achieve. Where the two intersect, that is the breast form size that will fill that bra. Example: 40C is a size 6.

Please be sure you want to keep your breast forms before you use any adhesives or apply an attachable form.

Breast forms that have been used with adhesives cannot be returned or exchanged.

For more information, please read our shipping & returns information.

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

Silver Seal, Gold Seal and Platinum 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.

Never sleep ON your silicone breast forms

Silver Seal, Gold Seal and Platinum Seal breast forms are also not guaranteed for use with any adhesives, with the exception of Double-Sided Tapes, Staysput, It Stays! adhesive and/or Skin Tac Wipes. Any other adhesive use with Silver Seal, Gold Seal and Platinum Seal breast forms will void this warranty.

Silver Seal, Gold Seal and Platinum Seal breast forms are warranted 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.

IMPORTANT: While many of our clients are using medical grade adhesives, adhesive sprays, medical grade tapes and removers with success, we regret that we cannot provide any guarantee if they are used. If you are considering any method of attaching Silver Seal, Gold Seal, and/or Platinum Seal breast forms, please do so with caution, knowing that this will void your warranty.


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.



All claims under this guarantee require the return of the breast forms to The Breast Form Store. Breast forms cannot be returned without a Warranty Authorization Number. Please contact us for an authorization 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.

    Beautiful breastforms. They feel real to touch and look gorgeous. The nipples are very realistic. Very soft (softer than my previous super softs), bouncy and the classic shape wraps round just underneath your arm giving you a natural looking breast shape. I bought the size 8. They are like a DD on me, I’m a size 14 / 38 – 40 bust. They stick nicely with the tape on as per instructions.

    The Platinum Seal is a beautiful breast form and as close to a real breast as you probably could get in a silicone form. Very very soft and natural looking. The Classic 1 wraps slightly underneath your arm at the side to create a very natural look and shape. They feel wonderful and the nipples are just perfect too. I love them more every time. They really do look like the ‘real’ thing! Very matt like skin, unlike so forms that shine. Very much worth spending a bit more if you can on such a high end product.
