1. Reformation Yale Dress

Reformation

No matter the time of year, you simply can’t go wrong with a floral maxi-length wedding guest dress. This Reformation stunner features a slight sweetheart neckline for a touch of romance, and the wider straps allow for a classic bra underneath to ensure you have ample support before breaking it down on the dance floor. The viscose material doesn’t have a tone of stretch, so I’d be sure to double check that size chart before you add to your shopping cart. Oh, and did I mention it’s fully lined so you don’t have to worry about any undergarment showing through that pale pink floral print? As with so many of the options on this list, this dress can be dressed up or down to fit a wide range of dress codes with a simple swap of your accessories.

Best Cocktail Dress

2. Reformation Casette Silk Dress

Reformation

Available in a range of super-flattering neutral hues, as well as at least one floral print (at time of publish), this silk beauty is sure to become your go-to favorite for any cocktail party or wedding reception. The high neck and slight draping around the waist are oh-so elegant, as are the wide straps that criss-cross in back. And the length is so flattering with both heels and flats. Being made of 100-percent silk, this dress is designed to fit close to the body without a ton of wiggle room, so if you’re between sizes I’d highly recommend opting for the larger of the two to guarantee room for a couple glasses of celebratory Champagne.

FAST FACTS

Size Range: US 0 to 12, also petite
Materials: 100 percent silk

Best Plus-Size Dress

3. Reformation Frankie Silk Dress

Reformation

One of Reformation’s few flaws is that it doesn’t have a ton of plus size offerings, but the ones it does have are reportedly well worth the splurge. That includes this gorgeous column dress (which also comes in petite sizes US 0 to 12) made of 100-percent silk. The silhouette is oh-so elegant and features smocking at the back of the bodice for a better fit around the bust. I will note, the straps are fixed in place, however Reformation does offer complimentary minor alterations for loyalty members at select store locations should you find you want them adjusted.

Size Range: US 14 to 24 (also 0 to 12)

Best Formal Dress

4. Reformation Camella Dress

Reformation

Just because an event’s dress code is listed as formal (or black tie, for that matter) doesn’t mean you’re doomed to an evening of uncomfortable attire. This fabulous gown is made of a lightweight viscose that won’t pinch or weigh you down on the dance floor. And while the back does have a gorgeous scoop cut, to balance out that high-coverage front, it’s still high enough to cover the straps of a classic everyday bra. It’s currently available in three solid hues and three prints, including trendy black with miniature white polka dots. P.S. Reformation does suggest going up one size from your usual in this style because of the fitted seaming around the hips.

FAST FACTS

Size Range: US 0 to 12
Materials: 100 percent viscose

Best Semi-Formal Dress

5. Reformation Kayla Knit Dress

Reformation

Semi-formal dress codes are a great opportunity to have some fun with shorter hemlines. The flared skirt of this fitted midi moves like a dream and the ruching around the bodice and hips is both comfortable and oh-so flattering. Add to that the stretchy jersey fabric and you’ve got yourself a no-fail party dress. There are four chic colors to choose from (though I’d save that ivory hue for a different occasion), all of which reportedly fit true to size. And as an added bonus, this semi-formal frock is also machine washable and dryer safe—just remember to stick with cold water and the delicates setting to avoid unwanted shrinkage.

FAST FACTS

Size Range: XS to XL
Materials: 88 percent Tencel lyocell, 12 percent spandex
Care Instructions: wash cold, tumble dry low

Best Black Tie Dress

6. Reformation Kastoria Dress

Reformation

Black tie events call for pulling out all the stops with your occasionwear. The delicate golden print of this floor-length gown is a fabulous option for any season, but there is also a springy blue floral and a dark green version if you prefer. The cotton-blend material is nice and breathable, but still has a crispness that maintains that upscale feel, almost like a men’s tuxedo shirt. The straps are both adjustable and removable if you want to rock a strapless silhouette, and there’s smocking at the back of the bust for a more comfortable fit up top. Plus, it has pockets—what more could a gal want?

Size Range: US 0 to 12
Materials: 98 percent organic cotton, 2 percent spandex

Best Dress for Dancing

7. Reformation Aiko Dress

Reformation

My absolute favorite part of any wedding is the dancing. Consequently, my favorite wedding guest dresses tend to be those that have great movement and that won’t need adjusting as I boogie (looking at you, strapless silhouettes). This floral number checks both those boxes, with the added benefit of a sexy-yet-chic silhouette. The delicate straps help keep the sweetheart neckline in place all night long, and are adjustable in back too. The dress is also fully lined for a more comfortable fit. As with many Reformation designs, the plus and petite versions come in fewer color options than the straight sizing, but there are still multiple season-less florals and a few solid hues to choose from.

FAST FACTS

Size Range: US 14 to 24 (also 0 to 12 and petite)
Materials: 100 percent viscose

Best Bridesmaids Dress You’ll Actually Wear Again

8. Reformation Jeany Silk Dress

Reformation

Between the beautiful draping of the silk charmeuse and the uncanny resemblance to Kate Hudson’s iconic yellow gown in How to Lose a Guy in 10 Days, this Reformation stunner is sure to be a hit with your bridal party. Of, course it also comes in black, navy, pale pink and ivory to fit whatever color scheme you’re working with. And all are also available in petite sizes to ensure the cut of that sexy low back hits exactly the right spot (no whale tails here please). It’s simple, it’s elegant and, despite the cliché, it actually would look very cute with a shorter hem if you wanted to get it altered after the big day.

FAST FACTS

Size Range: XS to XL, also petite
Materials: 100 percent silk
Care Instructions: dry clean only

Best LBD

9. Reformation Jamen Knit Dress

Reformation

Ideal for those occasions when you just feel totally stuck with the dress code or can’t quite figure out how to combine a brightly colored dress with other vibrant accessories, this LBD is an easy and chic solution. The stretchy fabric is incredibly comfortable, and can be ruched around your midsection to create flattering draping and a shorter hem if you like. The neckline feels wonderfully posh and adds more than enough interest on its own to eliminate the challenge of pairing a necklace—all you need are some statement earrings and you’re good to go. Just know, Reformation notes that this dress runs a bit big, so if you’re between sizes you may want to go with the smaller.

FAST FACTS

Size Range: XS to XL
Materials: 88 percent Tencel lyocell, 12 percent spandex
