Fergie has never really been one of my style icons, but prior to this outfit, she was doing quite well with her tailored shorts ensembles !
I can handle the crisp white button-down, oversized shades, and unassuming leather satchel, but they're hardly visible thanks to a bright orange (and is that patent I see?) cincher and the most loudly tie-dye jeans perhaps ever. There are ways to make tie-dye  look chic, but a smaller dose is key.
I would much rather see her in some midrise wide leg jeans  in an inky dark wash. The belt could be switched up in favor of a vintage brown one and the platform on those heels could be tamed down for a more daytime-appropriate look. How would YOU wear it?
