Thanks for all the comments.
On balance probably confirm my reservations- not keen on boring or 'nobody look at me'! Though equally don't like bright colour in winter, except in small touches.
Incidentally, Remus, do you have a preferred alternative for 'frumpy' - dull, boring, unstylish, etc?
Sadly I don't look like the model - I'm a large hourglass with a very big bust, though I am tall. Because of my height the tunic doesn't look as long on me as on model. And the neck isn't as high without the top the model has on underneath. It's V or scoop, which I usually prefer, but not a crew either.
Agree with poster who didn't like the other colour way - it sums up just what I don't like many Seasalt patterns.
If I did get this version, would wear it with grey skinnies, ankle boots or Converse- alikes, and long plainish silvery necklace. For casual wear only.
Having said all that, still not sure if I should keep it.
