Hi, I second cowl necks. Kaliko do quite a few. I wore this top yesterday with grey trouser suit. I have just looked and they have the top in olive green. I also have a top similar to this phase eight one.
I think those drapey tops although supposed to flatter big boobs add bulk. I like thinner no drape like silk/linen but may be too crumply for formal office wear.Collarless deep v silky shirts look great mango and zara have them
The other retailer I would recommend is Ann Taylor. American but now ship here. It's a workwear staple store in the US. I wore this top a couple of weeks ago with a black trouser suit and it looked great. V flattering.
this Austin reed top is £25 and got complimented a lot when I wore it. Flattering without being too 'booby'.
Magrat, yes I bought that top for nights out but realised it was versatile and works with so many different things and situations. The perfect top
