SIR the Label Wedding Guest Dresses for Every Dress Code

SIR the Label is one of the most useful labels for wedding guest dressing, because its silk dresses look elegant without upstaging anyone. This guide sorts the SIR. dresses on Coveti by dress code, from black tie to the beach, and flags the colours to avoid so you never arrive in something that reads as bridal.

Colours to avoid

Skip ivory, bone, cream, natural and butter for any wedding. They photograph as white. SIR. uses several of these shades, including the Alessandra in Ivory, the Ayla in Bone and the Aries pieces in Butter, so check the colour name before you buy. The safest SIR. colours for weddings are Bitter Chocolate, Black for evening, Navy, Dark Plum, Dusty Blue, Burnt Orange and the prints.

Black tie and formal evening

• Isla Cowl Back Gown in Navy, $1,160. Matte crepe silk, a straight neckline and a deep cowl at the back. The most classic SIR. gown for black tie.
• Flure Gown in Black, $1,410. Long sleeves, a low plunge back and a split to mid thigh.
• Noria Sleeved Gown in Dark Plum, $1,020. Silk with a cap flounce sleeve and a keyhole at the back. Ideal for autumn and winter weddings.
• Aries Long Sleeve Gown in Bitter Chocolate, $960. Bias silk with lace at the hem. See the full Aries collection.

Cocktail and evening wedding

• Lysia Halter Gown in Black, $1,160. Bias cut with a low back and floral embellishment on the straps.
• Olenna Twist Low Back Gown in Dusty Blue, $830. Heavyweight viscose with twisted straps and an open back.
• Lula Fringe Dress in Bitter Chocolate, $1,160. Silk on the bias with a cowl neck and a removable fringed scarf.
• Sona Maxi Dress in Geo Scape, $1,020. A graphic print for guests who want to stand out a little.

Day and garden weddings

• Gabriete Tie Shoulder Dress in Burnt Orange, $1,120. Silk satin with ties at the shoulder and the waist, and a high neck.
• Mireli Scarf Dress in Rose Parquet, $910. A long sleeve print with a tie at the front.
• Lilia Halter Maxi Dress in Daisy Meadow, $830. A soft floral in crushed silk and viscose, bias cut, with a removable lining.
• Estella Slip Midi Dress in Aliera Floral Blush, $720. A printed bias slip with a removable slip lining.
• Arisa Maxi Dress in Blur Poppy, $930. Silk lined in mesh, with gathers through the shoulder and skirt.

Beach and destination weddings

• Pernille Scoop Neck Maxi Dress in Sommer Stripe, $720. A linen blend with a twisted neckline.
• Estella Ruffle Maxi Dress, $900, a silk and viscose slip shape with frill panels. Note the Aliera Floral Ivory base is pale, so we suggest it for the rehearsal dinner rather than the ceremony.
• Phillipa Slip Dress in Eira Midnight, $870. A dark print slip with twisted straps, easy to pack.
• Arla Halter Gown in Cobalt, $1,060. A bright, structured halter for an evening on the coast.

Rehearsal dinner and the day after

For the dinner before, a mini works well: the Yasmine Mini Dress in Black, $780, in heavyweight bias silk, and the Arisa Mini Dress in Polka Dot Nero, $720. For the brunch after, the Sorrento Shirt Dress, $830, in silk with a tie at the waist.

How to finish the look

SIR. dresses do not need much. A strappy heel, a small bag and one piece of jewellery. The Signature Huggie Earring in Gold, $340, works with every dress here. For an outdoor evening, take the Dylan Blazer over the shoulders. More pieces in SIR accessories.

Editor’s note: a SIR. silk dress in Bitter Chocolate is my answer to most wedding invitations. It is formal enough for the evening and quiet enough that it will never look like you tried to compete.
