A Festive House Party

A Festive House Party

An intimate get-together requires both festive touches (hello, subtle sequins) and elegance. Pair a glittery blouse with embellished heels for the ultimate blend of sparkle and style. Rather than jeans, opt for sleek trousers, like this split-hem pair, to give your party look a comfy, versatile polish. Top it off with playful accessories like a bright bag in a trendy silhouette and hoop earrings with a modern twist. It's a look you'll be comfortable in no matter how long the night goes — and you'll never feel underdressed.

A Black-Tie Affair

A Black-Tie Affair

When just any dress won't do, make a statement in a floor-length gown. Perfect for your dressiest occasions, like a special date night or a wedding, nothing says glamour quite like the plunging neckline and ruched waist on this dress. The fiery hue will set you apart while giving your look a festive edge. Style it with minimal heels (we love the sparkles on this pair) and wow-worthy jewelry. A structured bag like this one pulls the look together, providing a polished elegance fit for an evening of enchantment.

A Laid-Back Brunch

A Laid-Back Brunch

Not all outings call for embellishments or heels. For times when cozy-cute is the vibe, slip into elastic-waist pants that may feel like pajamas but read much more elevated. A plush, oversize bomber jacket is about as comfy as you can get, and don't forget a pair of sneakers to round the look out and give it a casual, sporty feel. Whether you're brunching, shopping, or just chilling, these pieces give new meaning to relaxing in style.

An NYE Night Out

An NYE Night Out

When you're heading out on the town — especially on a night as legendary as New Year's Eve — standing out is a top priority. Pieces that boost your confidence are also essential. These high-waisted pants sparkle and shine for a memorable look that's both striking and comfortable on the dance floor. With so much going on from the waist down, keep it relatively simple up top with an all-black top and a vinyl black trench coat. Pearl hair accessories give the entire look an extra dose of brilliance, which you can never have too much of during the holiday season.

An Intimate Cocktail Hour

An Intimate Cocktail Hour

Whether you want to add a touch of glamour to your workwear or sparkle after sundown, a high-shine piece like this jumpsuit can easily take you from desk to dinner. Balance it with a tailored blazer you can wear yearlong — and easily shed once you arrive at your final destination. Pretty extras like glass-slipper heels, chandelier earrings, and a dazzling clutch ensure a show-stopping look fit for a magical evening.
