GET THE LOOK

Kendall and Kylie Jenner caused a stampede in Topshop's direction when they unveiled their new collection for the retailer in LA, with the black culottes Kendall wore at the launch proving an instant sell-out. But for once, Miss Jenner isn't ahead of the fashion curve, because culottes are all over the shops right now. Very has a great selection, including the soft and swingy South Jersey Culottes, £16 (www.very.co.uk).

Cape blazers make a great cover-up to sling over your shoulders on summer nights, but in black or block colours they can look a bit formal. Enter the When Life Gives You Lemons Cape Blazer, £60, from Kuccia, the zestiest jacket we ever did see. There's also a matching top and trousers, if you want to go for all-out fruit salad fabulousness (www.kuccia.com).

FASHION FLASH

:: TALL ORDERS

Plus-size fashion has been getting a lot of air time lately, but there's another size battle going on in the changing rooms of Britain. Started by 6ft graphic designer Sheyi Louisa Adelasoye, the Stand Tall campaign encourages women to take a photo whenever they try on clothes that don't fit properly because of their height, and post it online with the hashtag #standtallselfie. "If buyers knew how many tall women are out there craving more choice, they'd be inspired to extend their tall ranges," says Adelasoye.

:: STYLE STEAL

When the new season drops land, it's all about sensible investment buys, but right now, it's the summer sales, when impulse purchases are positively encouraged. Paul's Boutique is offering up to 40% off a gorgeous array of handbags, including the hot pink Maisy, £39, reduced from £65 (www.paulsboutique.com).
