about-onyx
a diminutive boutique in portsmouth

ONYX is a cozy, chic boutique where women can enjoy a unique shopping experience. Our shop and service are designed to mirror the ambience of your own walk-in closet. Our vision is that you’ll come to ONYX and escape in the peace and solitude of trying on our designer clothes as if you were in the comfort of your own home.

After all, isn’t that what it should be all about. We all crave an intimate shop where we can take our time, be unencumbered by others, feel as if this was our own personal space, and have the opportunity to see fashion lines that can only be found here at ONYX. Soon heads will be turning, wondering where you found one-of-a-kind clothing.

Our mission at ONYX is to offer designer fashions that are as unique to the Seacoast as the woman who will wear them. You’ll discover hand-picked selections to outfit a woman with their very own work-to-play wardrobe. We carry versatile lines such as Smythe, Theory and McGuire, offering a wide variety of styles for every occasion and mood. If you’re in the mood for fashion fantasy, we have select items from SOH, Re/Done and Mr. & Mrs. Italy. If you’re looking for a piece that is alluring, sophisticated, and almost hypnotic, you’ll only find it at ONYX.

At one time women enjoyed the fever of Filene’s annual “Running of the Brides,” where women jockeyed for a discounted gown, scorned at dressing rooms, and clawed with competing shoppers. That was then, ONYX is now. The talented hosts at ONYX will patiently assist in finding the perfect fit and style. We are here to ensure you find exactly what you envisioned, that flatters your look and spirit, and takes as long as you want the experience to take.
