I think the tattersall oxford is from AW12, Superdenim had it in their sale section. Somebody got a bargain if that price is true, http://www.superdenim.co.uk/prodpage.asp?productid=2607
. Having said that though, some of the patterns and cloths do seem to be recycled between seasons.
I went into Trunk yesterday and their British Army shirts were a lightweight cotton. Actually really nice and will be great in the summer whereas the ones in Present used the Japanese Oxford fabric. So, depending on what you're after take a close look at the fabric.
Really tempted by the lightweight sky blue one especially since Coggles have £30 off a £100 spend (think the code is Spring30 but its plastered all over their website) plus a further 8% off via quidco at the minute but I've spent a fortune recently so really should hold off...
