A range of sophisticated yet sexy boudoir lingerie, swimwear and leisurewear for all budgets and ages

What drives us is a love of boudoir lingerie, a passion for swimwear, and a desire for finding something sexy and different that makes us look like we just stepped out of a boudoir photo shoot. We appreciate quality & artistry. We love the unique and stylish pieces and we want DC lingerie lovers to be able to select from the most top-rated and award-winning lingerie for boudoir looks that will quite simply knock 'em dead. That’s why we have hand-selected every piece from award-winning independent designers in the US & Europe.

The opportunity to shop for your full wardrobe

More than just a lingerie or swim store, we offer shapewear, sleepwear, footwear and men’s ranges. Think of us as your one stop style boudoir in DC for when you want a look with a difference, whether its bridal, sexy, photo shoot worthy or simply for lounging.

The ability to discover small, independent and emerging brands

Every item in our lines is the best in its class. You may not have heard of all our brands yet, but you will - so be the first to discover them! The good news is ‘best’ doesn’t mean unaffordable. Yes, you can splurge on our divine boudoir lingerie (and we do every month!) but our range offers lots of unique designer finds for the underwear aficionado on a budget too. Whether it’s sexy, bridal or something else, we have it nailed.

A Price Match Policy

If you see something that we carry on sale somewhere else, we will try our best to beat or match that price. Just contact us!

About Us

Duchess of Dupont is a Washington, DC-based lingerie, swim, and leisure online retailer.  Launched in January 2018, our store aims to bring small, independent, and innovative brands to the forefront of the US marketplace. Bored and unimpressed with the lingerie, swimwear, and loungewear we kept finding at mainstream stores, we felt I had to roll up this sleeves and make a splash. Can one small retailer change the way America shops for intimates?  That is what we set out to find.  So think of us as your friendly, neighborhood DC lingerie and more online store. 

Duchess of Dupont is different from most other online stores.  The brands we carry are mainly small, independent and ethically-made. Because we have hand-selected each piece, we stand by its artistry and quality.  Many of these pieces are also made in the US and Europe. We also have incorporated items in a wide price range, making the store affordable to many.  We have immediate access to all inventory, so we can answer just about any question you may have.  

We are located in Washington, DC proper (Adams Morgan) and do accept a limited amount local customers, if you wish to have a more traditional shopping experience, by appointment only.  Just think of us as your online, friendly, neighborhood DC lingerie and more store!
