With London experiencing temperatures approaching 100°F, I could not think of anything worse to layer on a day this hot than Conner Ives Demi Couture fur-trimmed embroidered silk-mikado robe worn over an Olivia von Halle Issa Caramel silk satin slip dress.

Fashion and the forecast rarely agree, but there is a difference between making a fashion statement and setting yourself up for heat exhaustion.

And I am sure some will say, “It cools off at night.” Yes, but only to a very slight degree. Temperatures were still sitting in the high 80s last night, and even trying to sleep felt unbearable.

That said, this look speaks directly to Sienna Miller’s approach to dressing. She has long embraced a bohemian sensibility that is entirely unconcerned with practicality. The neon embroidered silk robe and dramatic fur trim introduce a level of drama that the dress alone could never achieve, which is perhaps precisely why it appealed to her.

Had the temperatures been 30 degrees cooler, I suspect I would have been much more receptive.

The Veil Melt gold beaded bag, Desert diamond Jewelry by Ara Vartanian and gold sandals completed her look.

Stylist: Clare Richardson.
