I was debating getting a large in this top but went for the medium, boy is it huge, the jersey fabric is quite thick which makes the sleeves bulky and uncomfortable, even the small would be giant! 
for reference i normally wear a size 8/10 my chest is 34 e and this was just so so huge, it hung so badly of my chest that it looked frumpy and made me look bigger than i am.
the colours are true and nice and vibrant... definitely size down with this one
