From Fleabag to fabulously fashionable: Phoebe Waller-Bridge's Hollywood glow-up as she steals the show at partner Martin McDonagh's Venice Film Festival premiere

The look still has that slightly nonchalant, individual quality that Phoebe is known for, but it’s been refined. 'That’s often what a real style transformation looks like not changing who you are, but turning up the volume on your best features.'Lisa continued: 'There’s also something very current about the simplicity of it. Rather than relying on lots of accessories or obvious glamour, the impact comes from beautiful proportions, strong tailoring and confidence. 'The oversized silhouette feels modern, while the monochrome palette keeps it sophisticated. 'Phoebe looks like a woman who knows exactly who she is and her clothes are now communicating that before she’s even said a word.'The actress has enjoyed a very successful decade with her career, finances, as well as in her love life.
