Perfect strappy top.

Being a lover of M & S long sleeved thermals I thought this was worth trying to wear under summer wear when not too warm. Excellent fit and cosy!

Useful warmth for blouses.

Yes, I recommend this

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

Cream thermal vest

Yes, I recommend this

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

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.
