White Co dresses, advice needed

[Pannacotta]

I have a White Co voucher which I'd like to use and want to buy one of their summer dresses.
I am quite straight up and down, probably a bit lanky, wide shoulders/ribs, small boobs and thick waist, flat tummy and bum, but good legs.

I lost a bit of weight recently when I was ill so look a bit scrawny if I'm honest, so am looking for something flattering.

Which one would be best for my figure?

TIA

If you're straight up and down, how about this? You'll need a tan though.

How wide of shoulder? So much so that you don't want to show them off? If you are happy to bare them, there are several like this. I have one and it's very comfortable but quite revealing. Again, a tan helps!

Thanks for the links fresh.
I like the first one but not sure about the high neck or the colour - also I wont have a tan until August after we get back from hols...

The second one I'd already picked as a maybe though I might need to wear it with a vest, don't have much cleavage to fill it out!

No tan? I have manufactured one in 2 days out of Johnsons Holiday Skin lotion....I smell a bit funny though....
