Not very satisfactory

Originally posted on marksandspencer.com (UK)

Disappointed with these breast forms, the nipple is too obvious and once you have them out of the packet there is no obvious sign as to which is left and which is right

I am not sure about this. It did the job of replacing my missing boob but it was rather too large for me and felt a little uncomfortable wearing it all day. I cannot dismiss it but need to try it for longer

The prosthetic supplied by my hospital is silicone and heavy. Whilst the shape and feel are good, in the recent hot weather it’s been a challenge. This insert is the other end of the spectrum, so lightweight it felt odd at first but I have grown to like it. So preserve if you are initially unhappy. It’s great value and so soft that I have been able to fit it into other clothes ie swimsuit.

Have recently had a lumpectomy and one breast is now visibly smaller than the other. This has helped me feel more confident and equal in looks and clothes fitting.

Does the job!

Originally posted on marksandspencer.com (UK)

Does the job and is more comfortable than the synthetic soft form given to me directly after my mastectomy. Is a good match for a B/C cup and easy to get in and out of bra's. The only thing I would mention that might be of interest is that if you are an older lady (I am 49) you are likely to find it to be perkier than your existing natural breast, but that's just me being highly critical as I've had comments from friends and family saying that you cannot tell that this is a fake boob.

Not very comfortable

This form would be ok in an emergency. Although the foam is soft it is not flexible. The NHS ones are much softer & mould to the shape of your chest.

Super alternative

Originally posted on marksandspencer.com (UK)

I needed an extra set to add to my NHS post surgery breasts. I have found these M&S suit me well, they are light and so comfortable to wear. I have a couple of sports bras with small pockets which the breast form fit well, also the price is great. I agree with other reviewers the nipple is not necessary. Thank you M&S

Breast Forms

Originally posted on marksandspencer.com (UK)

The Breast Form is very good value, I sent on the chance that they would be my size but as I am very small a much smaller size would be ideal. Nevertheless I have cut them in half and reshaped them to fit me.

This is good as an extra for short term wear but too firm and inflexible. More movement, please, M&S.

Finding prosthetics that aren’t heavy silicone, but still give a natural shape has been tricky. These M&S ones are just perfect. Will be buying more.
