Hmmm...
Whilst camel, almost invariably, looks rich and luxurious for winter, I think ecru (which, I suppose, is thought of as camel's summer equivalent?) is a far trickier proposition, to get right.
Especially if you're going to trifle with parchment-coloured, wrinkled chiffon with too many seams.
If you're going to do light neutrals for summer, as Gaby Aghion (who was born in Egypt, after all!) knows, I think you need to look to the colours of the desert and add a drop of tan and/or gold and/or pink and/or peach into the mix, to liven them up a bit.
The looks that worked best for me were the few, slightly darker, or richer, colours (the tan, the gold etc.) and/or the later dresses with the dew-drop-like embellishment.
Some of the looks, however, really were dangerously close to Mother of the Bride, IMHO.
On that note, I think if you were a day older, an inch shorter, or an ounce heavier than any of these models, you would struggle to find anything that did you any real favours...
