Hands down, this is the best place to find cufflinks in NYC (and maybe anywhere). I was looking for a vintage dress set for my wedding tuxedo and found Michael and The Missing Link through Citysearch. His selection of premium vintage cufflinks and dress sets is overwhelmingly impressive. Even more importantly, the customer service that he provides makes the whole experience of visiting his store a real pleasure. He helped me find the perfect set of Krementz abalone double-sided cufflinks and shirt and waistcoat studs (all in the original box from the mid- to late-1910s), and I couldn't be happier. Any time I need cufflinks in the future, this will be my first and only stop.
