influenced by nature. invigorated by seasons. inspired by women.

Shine Boutique is the creation of owner Erin Postl. She has called upon her creativity to combine her enduring love of fashion, passion for people, and affinity for nature to build a boutique filled with cozy clothing and unique jewelry. Energized by the seasons, Erin, her husband Ken, and their two boys Jackson and Oliver, find peace in the outdoors. As Erin developed her concept, she kept coming back to that central theme of the seasonality of New England and nature.  Ultimately, with support from her village of family and friends, she has created a modern, thoughtful, and highly fashionable boutique.

Committed to being the source for casual, versatile, well-made clothing in Newburyport, she has carefully curated a list of brands that reflect her style and appreciation of sustainability. Erin’s distinctive jewelry selection is comprised of handcrafted items from female-owned businesses.  She strives for the perfect medium, merging sustainable values with fashion in a creative, fun boutique experience.  Shine Boutique speaks to the woman who loves quality, accessible clothing; she looks for fresh styles that celebrate the seasons while making her feel cozy and confident – that’s what makes her SHINE!
