They say that you can never have too much of a good thing.

Well they have clearly never had to put their favorite dress into storage after mauling four pounds of chocolate. Or suffered a hangover after fifteen pomegranate martinis. Or faced a downright intimidating wall of designer denim.

Or maybe they have. Maybe they just had help from someone like Alison Barnard, owner of the newly opened Injeanious boutique in the North End.

Barnard’s shop is stacked with the likes of Chip and Pepper, Paper Denim & Cloth, Rock & Republic, and Hudson, plus up-and-comers like Taverniti, Meli-Melo, Arch Indigo, Puka, Denim for Immortality, and Loomstate Organic.

But the real score here isn’t just the jeans, it’s Barnard’s encyclopedic knowledge of her stash and her ability to instantly grab the pair that will fit like a dream and earn you endless compliments.

Something you can never, ever have too many of.

Injeanius, 441 Hanover Street, between Salutation and Battery Streets, North End (617-523-JEAN).
