I've found my white (and other colours) t-shirt holy grail...

[Celeriacacaca]

from M&S. Here is the grey www.marksandspencer.com/modal-blend-t-shirt/p/p60059532?OmnitureToPDP=+20401856&ddkey=http:MSSearchResultsDisplayCmd

and the white www.marksandspencer.com/modal-blend-scoop-neck-basic-t-shirt/p/p60059266#bvHeader

They're cotton/modal/elastane mix and are so lovely and soft. They're £12.50 each but wait for a 20% off promotion to order. Compared to the Next scoop neck ones and the Gap basics which I bought at the same time (which all now look like dish rags), the M&S ones look brand new and wash so well. I'm so happy that I have a good durable basic again.

Only need now to be careful with the suncream so I don't stain them !

It says they are limited edition. If you like them that much buy more because when they are gone you will be back to square one.

They're great aren't they? I have grey and black. I'm worried about M&S discontinuing them though as they've done that with lots of great Limited Collection basics in the past so I may well bulk buy...

Limited Edition is the brand name!

Off to order the grey one. Thanks for posting!

Sleeves are too capped for me :(
