Most Women dream of comfortable bras & these are. A pity they do not come in a variety of colours.

Fabulous!

The most comfortable Bra I’ve ever worn. I have two in white and two in grey. More colours would be great especially navy and black.

Not bad, a bit of bunching.

I like the style. Good neutral piece for under T-shirts etc which is what I was looking for. I'm glad the straps are completely adjustable. Unfortunately I get a bit of bunching at the sides, which is not uncommon with non-wired bras for me. I wish the cups were set slightly closer together. So I probably won't be a repeat buyer but fairly happy with the one that I have bought.

I have this bra in grey and white. Having always worn wired bras, I’m totally converted. It’s very comfortable and supportive. As expected from M&S, the quality is great and the fit is perfect.

Great for smaller cups and wider round the chest.

If you need a smaller cup but bigger round the chest, this is great. I’m 38a and it fits lovely and my profile looks better.

very comfortable and stylish

I found this bra very comfortable. When the back strap was engaged I found it helped me be conscious of my posture, which was unexpected. The only downside was that I had to take some pliers to the little hook in order to make the hook and eye to connect.

I’m extremely pleased with these bras. It’s quite difficult to find all cotton bras that offer good support and comfort as this one does. An extensive range of sizes meant that I was able to find my required size. The bras are also excellent value for money and had the option of matching knickers.

Great fitting bra, gives a great shape and hold even a larger bust. Love the racer back clip which gives so much versatility. Brought it in the grey too!
