O'Connell's is widely considered the last great bastion of authentic American Ivy Style. Located in Buffalo, New York, since 1959, the shop was originally a side venture for three professional football players but became an institution under the stewardship of the Huber family. While "preppy" fashion often chases trends, O'Connell's has survived by stubbornly refusing to change a single thing. They do not have sales, they do not follow seasonal fashion cycles, and they do not compromise on the heavy, durable fabrics that defined mid-century American menswear.

The store is often described as a "living museum" because of its legendary stock of "New Old Stock" (NOS). Because the Huber family rarely cleared out unsold inventory, customers can visit the store (or their text-heavy website) and purchase brand-new trousers, shirts, or jackets that were actually manufactured in the 1960s, 70s, or 80s. Beyond these rarities, they are the global destination for Shetland wool sweaters—stocking a rainbow of colors in a rugged, saddle-shoulder knit and the traditional "Sack Suit," keeping the unpadded, undarted silhouette of the Mad Men era alive in a world of slim-fit tailoring.
