recommend a nursing cover please?

[the why bird]

So I have huge boobs and last time never seemed to be able to master a discrete latch on - I always had to bare a lot of flesh to get her positioned etc and there was a lot of pulling off. So for my confidence I want a feeding cover this time for nursing in public.

I don't like the ones that look like an apron. I'd rather have one that I can wear as a scarf and just pull down and loosen for feeding time. I could knit one but for a summer baby I want something lighter and I can't sew.

Any recommendations? I am in the UK so preferably something sold here.
