Adele's Reformation dress has a waitlist of over 1,600

Adele has made headlines this week when new photos of her on holiday revealed the weight loss she achieved after going on the sirtfood diet.

The singer posed in beach pictures with Harry Styles and James Corden, looking amazing in a printed dress by Reformation. She also wore a similar style by the brand at Christmas.

Call it the Adele effect, but it now has a 1,600 strong waiting list and it's easy to see why. The singer wore the Alma dress in the splatter print style, and the print is also available on the Sigmund dress, which is coming back in stock and has a huge waitlist. Is is a midi length dress with a square neckline and slightly puffed shoulders and high slit which tick off key trends for the new season.

It's available in Black, Isabella (black floral print) and Splatter (navy and white paint splatter, the one worn by Adele) and is also available as part of Reformation’s extended sizing range (US size 14 - 24).

Although she's always loved fashion - she used to create scrapbooks of her favourite trends and looks, including Sienna Miller and Kate Moss' boho phase - her first job was at, sourcing the best deals for everything from restaurants to designer sales.
