100% cotton boatnecks

[IDugUpADiamond]

I need to keep my decolletage covered in the summer. Has anyone seen nice 100% cotton boatneck t-shirts?

I've just ordered a Boden Breton stripe one, from their younger Johnny B range here... 100% cotton and great reviews.

Seasalt Cornwall have some

I have previously bought lovely boatnecks from H&M and M&S (boatnecks really suit me). I'm afraid I haven't really been shopping recently to know, but certainly H&M tend to repeat things year after year in their basics.

Zara and Gap have them

Gap ones have odd shoulders. They sort of stick up and look odd. Was v disappointed.
