1. Mynt 1792 ($$$)
This NYC-based brand comes in sizes 12 to 26 as well as X to 4X, and includes a number of interesting textural pieces, asymmetrical looks, and a healthy dose of hardware and other metallic details. It's not exactly cheap, but their sale section offers goodies at up to 40% off.
2. Eleven60 ($$$)
Gospel royalty Kierra Sheard's debut collection is small but mighty, with super sexy and avant garde pieces available in sizes 10 to 22. Plus, all the "leather" involved (soft and luxurious as it looks) is vegan.
3. Eloquii ($$)
Eloquii offers a diverse range of pieces at accessible price points from size 14 to 28. It's not unusual to see significant discount codes floating around the site, and sale items are often 40% off.
4. Hey Gorgeous! ($$–$$$)
In addition to carrying contemporary brands like BB Dakota, Harlow, Line and Label, PLY, and Stefanie Bezaire in sizes 8 to 24, Hey Gorgeous! is set to become the first U.S. retailer to carry Marina Rinaldi Persona. They also offer significant price cuts on sale items, as well as frequent discount codes.
5. Navabi ($$$)
Navabi has a wealth of awesome designer duds in addition to their in-house line, ranging from sizes 12 to 28; and while at first glance it might seem you'll need a wealth of your own to afford anything, they routinely offer items on sale up to 70% off. For instance, both the printed chiffon minidress and the faux leather gilet above have been marked down from roughly $120 to $33.
6. City Chic ($$)
Like Eloquii, City Chic leans toward trendy, crowd-pleasing designs, including no shortage of peplums. If you're willing to put in a little work, though, you'll be handsomely rewarded with edgier pieces in sizes 14 to 24.
7. ASOS ($$)
ASOS's Curve section runs the gamut from cutesy to clean-lined, all up to size 26. Their in-house brand tends toward the affordable even when it's not on sale, plus Junarose, New Look Inspire, Pink Clove, Paper Dolls, and Truly You also offer some elegantly understated pieces.
8. CarmaKoma ($$$)
Based in Denmark, CarmaKoma offers dresses, separates, outerwear, and a denim collection with plenty of Scandinavian flavor in U.S. sizes 12 to 24. Shipping is free over $100, which shouldn't be hard to hit (perhaps unfortunately) in the full-price section — however, sale items are also listed at up to 70% off.
9. Elvi ($$)
This U.K.-based brand stocks downtown-cool garb in U.K. sizes 14 to 26 (roughly U.S. 10 to 18), and ships overseas. They offer some awesome prints if you like to mix those in once in a while, and items in their sale section are often marked at well over half off.
11. Boohoo ($)
This retailer's size 10 to 18 line is so well-priced (even without their frequent site-wide discount codes) that you can probably buy one of everything in each color for what you'd spend on a single item at a few of the other shops listed. Especially alluring are items from the brand's collaboration with model and all-around queen Nadia Aboulhson.
12. Additionelle ($$)
This Canadian brand in the realm of Eloquii and City Chic stocks casual, occasion, and workout clothing in sizes 12 to 24 and X to 4X.
13. Nordstrom ($–$$$)
There are a lot of brands to sort through in Nordstrom's plus section, but some more or less reliable ones include KUT from the Kloth, Pleione, Standards & Practices, Vince Camuto, Sejour, and Eileen Fisher. Sales regularly feature items at far beyond half off.
14. Mango ($$–$$$)
Violeta by Mango offers architectural dresses, separates, and outerwear up to U.S. size 20. Monochrome pieces made more dynamic by the use of multiple fabrics are a high point of the line.
