Beautiful sequinned floral embellishments make Needle & Thread's Wildflower Dress ($570) a true showstopper.

We love the gorgeous rose colour of Cinq a Sept's Winona Dress ($645), a satin dress with a ruched mock neck, tie waist, and ruffle hem.

Made from soft, lustrous velour, Yumi Kim's Goddess Dress ($248) is classic with a twist, thanks to asymmetrical shoulder straps — one draped cowl neck and one spaghetti.

In a lovely teal colour, Marchesa Notte's Mixed Media Gown ($1,195) will truly make you the belle of the ball. The intricate dress features a tulle draped structured bodice, mixed satin and tulle ruffles on an A-line skirt, and a decorative velvet bow at the waist.

A bold one-shoulder neckline with a decorative bow and tie waist add to the fun of Misha Collection's Moxie Leopard Dress ($380).

All-over floral embroidery and lace trim make Needle & Thread's Midsummer Dress ($489) so special. We also love the plunging v-neck and back and ruffled short sleeves.

The high-low hem makes a chic comeback in Temptation Positano's Prato Dress ($565). Crochet detailing and a smocked elastic waist add to the appeal.

A metallic floral print and deep v-neck in Ramy Brook's Metallic Jacquard Dress ($465) elevate an easy-to-wear dress.

Featuring an all-over light-blue-and-black abstract animal print, Solace London's Marne Dress ($413) is '80s fab at its best. A mock neck with attached extra-long ties gives it extra style points.

Sparkles and tulle combine in the dreamiest way in Marchesa Notte's Degrade Gown ($795), named for its sequin effect.

Black Halo's Darby Dress ($375) is unique with a one-shoulder design and a princess sleeve with an elongated cuff and collar tie.

We can't decide which element of Thurley's Folklore Print Dress ($348) we like best — the balloon sleeves, peplum skirt, or the lace-up bodice and shoulders.
