Summer is the season of weddings, showers, brunches, vacations, date nights, and just-because moments that call for something special to wear. Your perfect plus size occasion dress for summer is out there, and I want to help you find it.

Where to Shop for Plus Size Occasion Dresses for Summer
Anthropologie | 3X–1X
Anthropologie’s collection of plus size summer occasion dresses is full of delicate florals, puff sleeves, and soft, flowy fabrics that are effortlessly romantic.
ASOS | 26–14
For trend-forward pieces and a huge selection that are made to stand out in a crowd, look no further than ASOS They have a great filtering function on their website. I personally like to narrow my search to include ‘Plus Size’ for Body Fit and ‘ASOS Curve’ and ‘ASOS Design’ for Brand for best results!
Eloquii | 32–14
Eloquii brings vibrant color palettes, dramatic sleeves, and confident cuts to plus size occasion dresses. Much like ASOS, these looks are perfect for any event where you want to make a statement.
Kiyonna | 32–00
Kiyonna is a brand perfect for weddings, anniversaries, or even more formal evening events. Their dresses are equal parts comfortable and classic.
Old Navy | 30–00
Old Navy’s collection, The Occasion, dropped earlier this year with a goal of bringing elevated, event-ready fashion that is budget-friendly, inclusive, and stylish.
Torrid | 30-10
Torrid isn’t necessarily known for their formalwear, but for a more casual event, they have some great options. If you haven’t checked Torrid out lately, they have started releasing themed internal brands like Belle Isle (coastal and beachy) and FESTI (boho and flowy). Definitely worth checking out!
Whatever’s on your calendar this season, your body is already worthy of showing up and shining. The best plus size occasion dresses for summer don’t try to “slim you down.” These brands offer more than just clothing—they offer ease, celebration, and the freedom to take up space in something that feels right.
