Giant linen shirts?

[WanderleyWagon]

Hello mumsnetters, I am a large-chested size 18-20 looking for summer clothes for a work trip. I normally use loose trousers and a linen shirt, but my linen shirts are a bit snug at the moment. Has anybody perchance seen long linen shirts in stock anywhere for the generously sized?

The Lands End sale catalogue which arrived today has two styles of linen shirt with sizes up to 3X (equals UK size 30 apparently)?

H&M have some decent ones at the moment

Marks and spencer have linen oversized shirts up to a size 24
and in lots of colours
I have a white one though

Not linen, but Kin at John Lewis do over sized cotton shirts.

I bought some from Ulla Popken last year.

Cos do oversized linen shirts too

Thank you, everyone who answered! This is really really helpful and much appreciated. Tomorrow, I shop! :)
