Over the years, Katie Holmes has made one thing clear: she is a fashionista. When she finds a silhouette that is comfortable and stylish, she can often be seen repeating that style in wardrobe form, like a song in her ears. As New York City transitions to warmer (and more humid) days, Holmes is already looking ahead to summer by (temporarily) swapping her favorite jacket and sneakers for slip dresses and moccasins.

The Dawson's Creek star was photographed in New York City on Thursday, May 9. Chatting on the phone, the 45-year-old wore a sleek black midi slip dress. Holmes wore a dark green and brown tank top layered underneath. (The off-duty look may have been due to layering advice from Holmes' longtime stylist, Bree Welch.)

The exact credits for Holmes' costume have not yet been released. As far as we can tell, Holmes adorned her silky gown with a black leather shoulder bag, a dainty gold necklace, and gold-framed sunglasses. She also added an unexpected twist by completing the look with beige moccasins rather than re-wearing ballet flats or chunky sneakers.

Now, here's where Katie Holmes comes in to repeat her outfit. Actress Katie Holmes wore the exact same slip dress last Wednesday, May 1, running around town as usual. On this occasion, she paired it with a maxi-length tote bag and a pair of dark blue velvet mary jane flats from Vibi Venezia. Underneath, she paired a pink and red tank top, adding a pop of color to her almost monochrome outfit.

Holmes' reign as a street style star is due to his insistence on wearing his favorite items over and over again. Whether it's a trench coat or a tote bag, she's always rotating her favorite styles, experimenting with styling to make them look (and feel) like new.

It's never too early to start summer shopping, and luckily, the actress has already provided some easy and refreshing outfit ideas to recreate for the upcoming season. Keep scrolling to shop Katie Holmes' slip dress and moccasins...
