Useful warmth for blouses.

Very useful vest which adds a fair amount of warmth to summery blouses in spring. Would have preferred a shorter length.

I’ve got loads of M&S thermal tops. In UK it’s still a bit chilly even in summer months. I bought these strappy vest thermals to wear as a light layer under my clothes. I’m a 10/12 on top half. I bought the size 12 as I didn’t want it too clingy.

Nice warm material to go under tops when you feel you need just that little bit more on those in-between days.

Lovely material

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Lovely material, but so long. Because it is so long it ruffles up when wearing trousers, I’m 5”6 so I can’t imagine how someone not as tall coped. Also the straps are not adjustable. Shame because the inside is superb.

The vest was really warm on the inside as mentioned & I found it so nice that I bought another in brown. I bought a bigger size than normal & it was longer in length

Very warm, perfect for spring weather

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Ordered this in the pale colour. Despite being sleeveless it's very warm, so it's perfect under a blouse in spring. I was worried my arms would be cold, but the heat it retains keeps my whole upper body warm. It is a long garment, covering part of the butt, but I assume this is to better insulate your whole torso from the cold. It is thicker than an ordinary vest and very soft.
