How to Survive a NYC Heatwave in Style (and Sustainably)

Summer in New York is not for the faint of heart. There comes a point in the summer, somewhere between your third iced coffee and second outfit change that you start to question why you ever romanticized this city. When NYC turns into a steamy concrete sauna, traditional outfits just don’t cut it. Linen gets wrinkly, denim gets sticky, and walking a few blocks feels like a full-body workout. So what’s the secret weapon in our summer wardrobe?

Swimwear.

Yes, you read that right.

When it's 100 degrees and rising, swim fabric is your best friend. Quick-drying, breathable, and sweat-resistant—basically made for the elements. But don’t worry, we’re not suggesting you show up to your 9-to-5 in a string bikini. We’re talking vintage one-pieces, bold tankinis, and retro swim tops. Think less “bikini at brunch” and more “one-piece as bodysuit” chic. It’s not about looking like you're headed to the beach, it's about dressing like you’ve mastered the art of staying cool without sacrificing style.

And let’s be honest, isn’t that what summer in New York is all about?

Vintage swimwear offers that rare combo of form, function, and flair. The silhouettes? Flattering. The patterns? Unmatched. And best of all, styling a swimsuit as a bodysuit or crop top is a sneaky sustainable way to beat the heat without constantly reaching for fast fashion.
