If there's someone we trust to serve as serious fashion inspiration, it's Lily James.

The British actress, 37, seldom disappoints with her summer sartorial portfolio, but the same is also true when it comes to her glam.

In an under-the-radar outing, the Swiped star quietly debuted what appeared to be newly dyed flame-hued tresses while stepping out at the press night after-party for End Of The Rainbow at Soho Theatre Walthamstow last month. 

For the occasion, Lily oozed cool-girl chic, wearing oversized black jeans, a pin-striped shirt and leather jacket, with her flame-hued locks taking centre stage. Lily completed her look with a pair of crocodile-print boots.

The starlet's stands were styled into immaculate mermaid-style waves, which cascaded past her shoulders. As for her makeup for the occasion, Lily opted for natural glam comprised of subtle mascara, light touches of rosy blusher and nude lips. 

Lily's holiday wardrobe

Whether she's stepping out at fashion week or enjoying some well-deserved R&R, Lily always looks spectacular, but seeing as the weather is scorching, we feel our attention should go on her perfect holiday wardrobe she displayed earlier this year.

Batting away the January blues, Lily jetted off for a girls' trip to Mexico. During the lavish trip, Lily stepped out in a selection of stunning holiday looks.

"Girlfriends [infinity emoji] in paradise. The most magical start to the year @hotelesencia - such a special place & memories to forever cherish,"  Lily penned of her time away. 

One standout ensemble was a sheer black number the actress wore. Oozing A-list glamour, Lily chose a sheer maxi dress, adorned with a floral pattern in blue.

Under the gown, Lily's orange bikini showed through, making it the perfect day-to-night addition to her wardrobe.

Fashion advice 

When it comes to her fashion, Lily previously told Elle that she "has to feel confident in what she's wearing."

"I work with my stylist, Rebecca Corbin Murray, to find an outfit that looks and feels right. It really is a strong feeling as soon as I put the right outfit on. We’ve worked together for a lot of time, so there’s a great synergy between us. I have to feel confident in what I’m wearing, and if I don't, I feel so nervous, and I can’t walk out the door," the SAG Award-winning actress said of dressing for a high-profile event.

As for her own personal, day-to-day style, she explained: "I'm very low-key in my personal style. I am always dressing up for the characters I play and different events I go to, so in my downtime, I love to be quite simple and effortless. Good tailoring is key, as well as a great handbag."
