Subtle Sparkle

Yes, I recommend this

I have a number of these thermal tops which I generally wear as a base layer. This one deserves to be seen more as it has a sparkly thread. I wouldn't wear it on it's own as it's clingy and reveals all lumps and bumps but I wear it under a low cut top and also under a sleeveless top so the sparkles can be seen. So it keeps me warm while adding more style and a bit of shimmer

Nice warm winter top

Yes, I recommend this

Lovely brushed finish inside, making this a warm top to wear. Fun sparkly finish, but it's a shame it comes in so few plain colour choices for everyday wear. How about adding in a lovely bright Christmassy red, holly leaf green, sunshine yellow, cornflower blue etc to widen the range ?

Love the warmth of this figure hugging sparkly top. Smart but also casual. Great quality too. I keep going back to buying this one, it is so comfortable.

Nice and Warm

Yes, I recommend this

Great thermal top with a bit of a sparkle. I have this top in various colours and wear them all winter long. Great under cardigans and jumpers. Not see-through at all. Was very well. I size down in these as i like them fitted and they are stretchy.

Sparkly thread - Sensitive skin

The top fitted well but unfortunately the sparkly thread irritated my sensitive skin when I tried it on so I had to return

Disappointed

No, I don't recommend this

I was very disappointed with this sparkle thermal top. It was far too long in the body and the sleeves and the material was quite rough. I given it one star and returned it.

Thermal Sparkle

Yes, I recommend this

Excellent bit of sparkle added to thermal top. It not only keeps me warm but is a very versatile garment to use under clothing or stand alone under a jacket and still looks good.Washes well too. Even though it’s got sparkle it is still soft to the touch.

Very soft sparkles.

Yes, I recommend this

Lovely soft top. I love the whole thermal range and wear them lots. I bought this for a night out with the girls to wear under a plain sleeveless jumper. The sparkles are quite subtle and it works perfectly.

Sparkly thermal top

Bought sparkly version to wear under dress at Xmas. Definitely warmer wearing it. Good quality and nice design. Sleeves a little shorter though on this version compared to crew neck version.
