The second law of thermodynamics and the first law of Nelly lyrics hold that ambient heat and clothing have an inverse relationship. Disturb the natural order with today's Groupon to Treat, the Alexandria boutique that offers designer women's apparel and accessories at sample sale prices every day. For $45, you'll get $100 worth of chic bags, dresses, pumps, tops, jewelry, and more. Washington Post Express named Treat the area's best indie women's boutique, and the Washingtonian calls it one of the best shops in Old Town, not to be confused with the "Oldest Shop in Best Town," which is still Cobblers 'N Things.

Unlike the vendors who in ancient times ran to the morning trade ships to view the latest fashions from across the sea, Treat is set in modern times and has plenty of affordable products for everyone. Between sea-foam green walls, the spacious and well-lit boutique organizes a well-edited stock of discount designer fashions on brilliant white shelving. Treat's inventory is updated every week or two, just like your mom's Facebook profile, with new dresses and tops from designers such as Diane von Furstenberg, Nanette Lepore, Milly, Vince, Trina Turk; denim from Joe's Jeans, J Brand, Seven for all Mankind; shoes from Bettye Muller and Loeffler Randall; and handbags from Kooba, Hayden Harnett, and Marc Jacobs.

Because each item is handpicked by Treat's savvy fashionistas, you won't waste time and wear out your hanger-sliding arm searching for something stylish. Check out the charming shop's blog to preview new merchandise before you hit up the shop for its myriad fabulosities. Accent any outfit with a gold snakeskin clutch from Chocolate Blu ($62), or stock your closet with Monica Ricci's embellished version of the timeless little black dress, belted with pleat trim ($89). Put your Groupon toward a statement piece, such as a Trina Turk zebra-print trench coat ($199), or make even a plain T-shirt pop with a delicate necklace by Ruth Barzel, with silver chain interrupted by ovals of rose quartz ($75).

Visit Treat Wednesday through Saturday 11 a.m. to 7 p.m. and Sunday from noon to 6 p.m. Though you can't combine your Groupon with special offers or promotions, you can use it to snag any of Treat's clearance items, which is like wrapping a cool bargain in an toasty electric savings blanket.

Reviews

The Washington Post Express calls Treat DC's Best Indie Women's Boutique, and the Washingtonian lists it as one of the best shops in Old Town.

Yelpers give Treat a solid 3.5 stars:

• The bags and shoes are the best part of this place, IMO. As much as I love Marc Jacobs bags I just can't bring myself to buy one--but Treat makes it a [sic] attainable goal… – Courtney R.
• Stores like Treat leave me wondering why I don't shop in Old Town Alexandria more often! I was especially excited by the Grace Sun offerings which haven't been easy to find elsewhere in the DC area. – MiRIAM w.
• There is always something new and fun in stock - and they have all sizes which I appreciate. The sales lady there was very friendly and helpful. – Jessica M.
