Karla Welch is a Who What Wear editor in residence and one of Hollywood’s most influential stylists, working with clients such as Olivia Wilde, Tracee Ellis Ross, Sarah Paulson, and Tessa Thompson. She is also the founder of The Period Company and xKarla.
After an intense few months—returning from Paris Fashion Week and immediately jumping into fittings for the London Film Festival while preparing for the Academy Museum Gala—Welch decided to shift focus. Instead of talking about red carpets and runway looks, she’s sharing something more personal: what she wears at home on a relaxed Friday night, watching sports on the couch.
She highlights this outfit because every piece she’s wearing reflects her personal style and daily “uniform.” Even more meaningful, each item comes from a female-founded small business. It’s her go-to look for unwinding after nonstop work and travel.
At the core is her ideal white T-shirt, created in collaboration with Michael Stars. While many may know her for her xKarla tees, this latest version stands out. Priced at $48, all proceeds support The Period Abundance Foundation, which provides sustainable menstrual products to those in need. She wears these T-shirts constantly—even in Paris, where they drew plenty of attention.
She pairs the tee with her favorite gray sweatpants from Los Angeles–based brand BAA. With a nostalgic, slightly retro feel, they resemble the kind of sweats you’d see on a charming ’80s movie character. They’re versatile enough for travel, weekends, or even styled up with a blazer and polished shoes for an effortlessly cool look.
On her feet are luxury socks from Comme Si, a New York–based brand that produces in Italy. Though pricey, they offer exceptional comfort. Welch is especially fond of their sporty styles and vibrant colors, often gifting them to friends—who quickly become fans themselves.
Finally, she shares a candid detail: she’s currently on her period and wearing Sporty Stretch period underwear from her own brand, The Period Company. After decades of experience, she considers this product a game changer—comfortable, reliable, and a significant improvement to her everyday life.
