Poppy Delevingne: She Wears It Well Model Poppy Delevingne opts for the midi dress, the perfect length for 'now'. I wish I was wearing this outfit today, instead of the ridiculous get-up I've got on. Boots, for goodness sake. (According to my HTC it was definitely going to chuck it down. Meanwhile the sun beats down.) Anyway, this light and airy ensemble by Jonathan Saunders, worn by Poppy Delevingne in Madrid on Tuesday is a delight, particularly teamed with the bright, ethnic-style clutch (take another look at your make-up bag, you could have a great accessory there) and blingy sandals.

Caroline Sieber was in a similar midi-length dress by Chanel at the Serpentine Summer Party and it feels fresh and elegant. It's the perfect length for a summer wedding (just add clashing bag and shoes) and you can be so much more economical and slapdash with the fake tan, no? Conveniently, Net-A-Porter.com has its own 'midi' length dress section and there are some lovely examples in the sale. If you're quick about it you could snap up a frock at just the right length and just the right price.
