Try Dorothy Perkins (also on the website in raspberry and white). I've got a couple of 3/4 length sleeve ones from them, and like them a lot - no lycra though, but they seem OK. Can't see long sleeved versions, but maybe in the shop you'd find something.
i think my breasts would look awful in that cod-although i did see a lovely white embroidered shirt type thing in m and s earlier that i though would be good. then i had big doubts about practicality of wearing white when working in year 1!
Okay, they're maternity ones, but they will do non-maternity ones too if you phone up and talk to them. I [heart] Harry Duley, they are hugely comfortable, wash well, and they are v. helpful if you phone up with special requests. I have a non-maternity version of the tunic linked to above in a dark red colour which they made for me in the spring after my other one finally expired.
Katisha, that is exactly what I have. And I wear them really a lot. I was heartbroken when my old one died after several years of hard wear, and very when they kindly agreed to make me a new one. I think I might even need another one in a different colour.
