Fashion advice

Try House of Bruar cotton polo necks (£19.99) and they really keep their shape. Not sure if they have cream but have a look online.

I'd also recommend uniqlo. They are thin enough to wear under anything but are great at keeping you warm

Thank you so much, lots of great ideas so I am now browsing the internet.

I've got two or three polo necks with long sleeves. The cotton one is from Cotton Traders and two polyester ones are from Tesco. They are thin enough to go under tunic dresses.
Have you tried looking for base layers in the sports shops.

I have just fished the Damart catalogue out of the bin for this info. Long sleeved turtle neck, but no cream It comes in several colours including pale beige.
Good luck with your search.

Try Lands End - Women Polo Necks & Roll Necks
I have had them in a variety of colours in the past

Cotton Traders.?

Try menswear for a longer version of the same basic foundation warm garment.
