US Open outfit ideas! The last Grand Slam tournament of 2025 is coming up in about a month and I have some outfit inspiration. I love blending the tenniscore and coastal aesthetics for smart casual looks. I also love a cute tennis accessory like jewelry, handbags, and hats so I linked a bunch of those too!
