Packets without Black Please

why must you have a black in every time - the natural ok but black. Do that colour separately. I continue buying because they are the ones I like but black one wasted every time would not need the purchase this time if extra blush or white instead of blck

Disappointing

Yes, I recommend this

This extender keeps coming undone. The little hooks need to be more bent.

A must for those with fluctuating weight

Yes, I recommend this

I bought these to allow for the weight gain expected with Chemotherapy. They allowed my current post surgery bras to comfortably fit me throughout and after my treatment. They are a must for people like me whose weigh fluctuates over time.

Useful when surgery means your size changes

Gives you breathing space post surgery with the bras you have until everything settles to know what your new bra size is.

Great quality and such a relief

I was so pleased to discover three hook bra back extenders on M&S website to fit my M&S three hook bras. This is such a better alternative to the various sports bras I ordered which were too tight for my injured back.
