Sienna Miller boarded the Eurostar in the stylish outfit that I always choose for traveling.
Years in the fashion industry have made me realize that perfecting the art of travel attire is quite a challenge. While comfort is always a key factor in my everyday outfits, it becomes even more essential during travel, with its high step counts and lengthy waits that are often involved. However, there's something to be said for arriving at your destination feeling polished, especially if you want to dive right into your plans. That’s why I rely on a few proven travel essentials whenever I travel abroad. It seems that Sienna Miller shares the same perspective. As an experienced traveler, she was recently seen effortlessly navigating through King's Cross St Pancras with a suitcase in hand, dressed in a stylish spring outfit that embodies the very formula I depend on for travel days. After a busy week in Paris, Miller arrived in London via the Eurostar, showcasing the single shoe trend that I believe is essential for frequent travelers: ballet flats.
These elegant and practical shoes are comfortable enough for extended periods on your feet and are easy to take off and put on during security checks. Miller opted for Gucci Horsebit Ballet Flats, hitting one of the season's favorite trends while ensuring comfort. She paired them with denim, selecting a relaxed, frayed-hem style that added a casual yet intentional vibe. Layering on Chloé's Double-Breasted Wool-Blend Tweed Coat (£1614), Miller’s outerwear provided just the right warmth for those unpredictable early spring temperatures.
Although Eurostar security is generally much easier than air travel, I still advocate for a hassle-free shoe. Whether passing through a checkpoint or simply wanting to change into something cozier mid-journey, a shoe that looks polished yet is easy to slip on and off is always on my packing list. Then there’s the discussion about jeans. While some might avoid denim on travel days, considering it constricting, I contend that the right pair—relaxed, wide-leg, and well-worn—can be just as comfortable as leggings or joggers. Plus, they instantly elevate an outfit, ensuring you arrive looking as polished as you did when you departed.
Having spent years perfecting my in-transit wardrobe, I can confidently say that this look is worth saving for your next trip. Keep reading to learn how to replicate the outfit below.
