It should feel like borrowing a wardrobe from someone with very good taste.

Thomas Harrington opened the shop in October 2006 with about forty pieces on the floor and a very specific idea: that a boutique should feel like borrowing a friend's wardrobe, not walking into a department store. The name came from a stone he carried in his pocket during a buying trip through Lisbon, and a word his grandmother used for the small rituals that keep a day from feeling disposable. The two things seemed to belong together. The first winter was slow. He sold enough to stay open, and that felt like enough.

The turning point came in the spring of 2011, when Thomas began working directly with a small linen mill in northern Portugal whose owner was looking for American retail partners willing to commit to full runs rather than cherry-pick individual pieces. That relationship changed how the shop bought. Instead of filling gaps in a trend-driven calendar, Peridot Mantra started building a floor around a handful of makers whose work held up over multiple seasons. Some of those relationships are still active today. The Portuguese linen pieces from that first full run are still the most-requested category in the shop.

What we pay attention to

The hand of the fabricEvery piece is touched before it is ordered. If the weight or drape is wrong, it does not come in.

Labels that make fewer thingsWe work with ateliers that produce limited runs. When a run sells out, it is gone.

A floor that changes slowlyWe rotate the collection seasonally, not weekly. You will not find last Tuesday's trend here.

How to choose a coat that lasts a decade

Buying a coat that lasts a decade requires asking a different set of questions than buying one that looks good in the shop.
