The Core Shirt | Anti-Gaping, Adjustable Fit
Description
Meet the shirt — the one you’ll build every outfit around. Introducing The Core Shirt — the elevated essential designed with intention.
Every line, fold, and fastening has been thoughtfully considered to bring luxury ease into the everyday.
Finally, a shirt that actually fits. The FEMSS Core Shirt is designed to flatter both fuller and smaller busts, so you’ll never deal with gaping buttons or compromise between fitted or oversized. With discreet anti-gaping clips at the bust and waist, this shirt smooths and supports exactly where you need it.
Made from a soft cotton-rayon blend, it drapes effortlessly and feels as good as it looks. The adjustable waist toggle lets you choose your perfect fit — relaxed, cinched, or somewhere in between. Deep structured cuffs, hidden elastic button loops, and subtle embroidery give it that polished, elevated finish that feels Pinterest-worthy without trying too hard.
Whether you’re heading to work, meeting a client, or grabbing coffee with friends, the Core Shirt gives main character energy — effortlessly confident, timeless, and versatile.

Fit Notes
The tank is designed to provide Bra-Free support with a snug fit, while the high sides allow for the option to wear a strapless bra with full coverage if needed.
If you are in-between sizes , we recommend sizing down.
If your waist is small compared to your chest, we suggest choosing the size closer to your waist measurement.
Remember the size defines the shape of the clothes, not you!
