It's becoming obvious that the rustic, hippie look isn't working anymore. Chloe needs electricity and excitement again. Of course they need desirable bags, but their success will depend on the appeal of Chloe's brand image, especially at a luxury price point. Discarding of the sustainability strategy would be a bad idea. Chloe is the only major luxury fashion brand to be a certified B-Corporation and would to be very smart of use that title to their advantage.
Lotta does have that creative credability and editorial pull Chloe desparately needs, that said, it doesn't always promise sales. Brognano's Blumarine had the added cache of Lotta Volkova, Harley Weir and Petra Collins, along with the adjacent rise (and fall) of Y2K aesthetics in pop culture, but it never translated into actual sales.
