Great vests

Yes, I recommend this

Love these vests. They are so thin, but warm and therefore can be worn 'invisibly' under tops/shirts etc. I used to buy similar from Uniqlo but they don't make this style with the thicker straps anymore. I wish M&S would do this style in more colours, especially navy and white.

Perfect Winter Wear

Yes, I recommend this

I am so glad I bought these vests. They are long and stay in place when I'm bending over, gardening. They are stretchy and fit snugly with no shrinkage after washing. Perfect for these cold, wet winter days.

Not great

No, I don't recommend this

The vests are comfy to wear, however I don't find them much warmer than a standard vest and after a couple of wears they have bobbled under the arms

I love them. I don't need to have a bra under. They hold my breasts- great unexpected bonus. I no longer have back ache. I love them that much that i have order another set. Great material quality. Look great after wash. Do you do them in skin colour or white ?
