TRE Boutique, a women-owned clothing store at 2690 Via De La Valle D240, Del Mar, CA 92014, has roots in Del Mar that stretch back more than 35 years to when founder Bobbi Martini opened The Rare Earth boutique. Today her daughters Sheree and Rochelle run the operation under the TRE name with a second location in Encinitas, carrying designers including Hale Bob, Liverpool, Joseph Ribkoff, Bailey 44, Michael Stars, Bella Dahl, Mauritius, PJ Salvage, and Hammitt handbags. The Del Mar shop sits inside Flower Hill Promenade, and nearby Matti D on Via De La Valle offers a complementary high-end boutique experience for shoppers who want to compare styles in a single trip. New merchandise arrives daily, and the staff is known for pulling looks that customers describe as spot-on, often introducing pieces shoppers would not have selected on their own. TRE is open Monday through Saturday from 10 AM to 6 PM and Sunday from 11 AM to 5 PM, with curbside pickup and in-store pickup available for online orders. Orders over $200 qualify for free shipping with the code FREESHIP. After browsing, walk over to Flower Child at Flower Hill Promenade for a quick healthy lunch without moving your car. With a perfect 5.0 Google rating, TRE reflects the kind of repeat-customer loyalty that comes from three generations of family retail experience in coastal San Diego.
