LONDON — The weekend moved at a breakneck pace this season, taking industry insiders to London’s four corners to see all the designers had to offer. But there is no rest for the wicked, and the schedule was only just ramping up to Monday, the busiest day of them all. Here’s what is coming:

• There were plenty of designers in attendance at the Downing Street curtain raiser to fashion week on Thursday night, but only one appeared to have dressed half of the movers and shakers in the room: Roksanda Ilincic. The Serbian-born, London-based designer had both Natalie Massenet and Samantha Cameron wearing her creations, not to mention two women wearing the same black and yellow shift dress. Her latest show — no doubt packed with plenty of her usual signature color-blocked, sculptural designs (Michelle Obama and Melania Trump are also fans) — kicks off the day.

• Front-row whispers of the name Huishan Zhang have been reaching fever pitch in anticipation of his first stand-alone catwalk show this afternoon. Mr. Zhang, born in Qingdao, China and based in London, gained experience in Dior’s haute couture atelier before introducing his namesake label in 2011 and having his London Fashion Week debut in September 2012. Since then, his collections have been sold at Browns, Moda Operandi and Bergdorf Goodman; he also was among those said to have been considered to replace Alber Elbaz at Lanvin earlier this year.
