Good shape

The bra gives a good shape especially if your boobs have lost their youthful firmness. The actual cups are quite heavy though so you need to get the straps right or the whole bra sort of sags downwards.

Cotton Bra with no underwiring which I always find uncomfortable.

Love the cotton fabric. Breathable, beautifully designed and gives a lovely natural shape under your clothes despite being unwired. Very comfortable to wear. Will buy again. Nude colours next please.

Very comfortable

Bought on impulse but very pleased as comfortable and a good fit. Like the band under the cups and the cotton content- ideal in the hot weather. Have since bought again in white and wish it was available in black or other colours.

Lovely well-fitting bra in a very welcome cool cotton finish. Very easy to wear during the current heat wave, and it looks pretty!

Too small for stated size.

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I measured under my bust several times before ordering, each time the tape measure read 36 inches. However, this "36" D bra is so tight around the ribs I can't do it up. The D part of it is fine. I'm waiting on a better bra extender before wearing this, though I was hoping to avoid this kind of thing. Not very pleased about this.

Comfortable , cotton and good value

It is so nice to find a bra that is not wired and is sold singularly. This bra is not only comfortable but it is made of cotton. So few are. I wish Marks & Spencer would sell more plunge bras like this.

Convert to this comfortable cotton bra.

I am a complete convert. Usually wear plunge wired styles which tend to ride up your bust. This cotton bra offers a wide supportive underband. The cups shape and support.
