What to Wear Over a Wedding Guest Dress
Whether you’re attending a spring wedding with a breeze or a winter ceremony in cooler temps, knowing what to wear over a wedding guest dress is key. The right layer completes your outfit while keeping you comfortable.
For spring and summer weddings, consider a lightweight shawl or chiffon wrap. These add a touch of coverage without overheating, and pair beautifully with sleeveless dresses. A soft cropped cardigan is another great option for garden or registry office weddings.
Attending a more formal or autumn/winter wedding? A structured blazer or tailored jacket adds sophistication while keeping you warm. For colder months, a longline wool coat in a neutral tone can complete your look while still allowing your dress to shine.
Our collection at Style Boutique includes occasion-ready cover-ups, jackets, and layering pieces designed to complement our wedding guest dresses perfectly. Whether you prefer something classic or modern, we’ll help you find the right finishing touch.

Can a Guest Wear White to a Wedding?
This is one of the most asked questions — and the answer is usually no. Traditionally, guests should avoid wearing white to a wedding so as not to compete with or overshadow the bride. Even ivory, cream, or pale champagne tones can be risky unless the invitation specifies otherwise.
Wearing white has long been reserved for the bride. Even off-white shades like ivory or cream can appear too bridal, which risks causing unnecessary confusion or taking attention away from the main event. To stay on the safe side, it’s best to avoid wearing white altogether — unless the couple specifically requests it as part of the dress code.
That said, there are beautiful ways to wear light colours without crossing the line. Florals with white backgrounds, pastel tones, or prints that soften the overall look are great alternatives. At Style Boutique NI, we stock a wide range of wedding guest dresses in flattering colours and prints designed to suit every age and body shape.

How to Accessorise a Black Dress for a Wedding
Wearing black to a wedding is no longer taboo, especially for autumn and winter events. A black dress offers a sleek, classic base — but how you accessorise it makes all the difference.
The key to making a black dress wedding-appropriate is all in the accessories. Start by adding a pop of colour — bold statement earrings, a vibrant clutch, or brightly coloured shoes can instantly lift your look. Jewel tones like emerald, ruby, or sapphire work especially well for autumn and winter weddings.
For a softer feel, especially in spring and summer, choose pastel accessories, metallics, or florals to lighten the look. A colourful shawl or a printed scarf can add interest and balance.
Finish your outfit with delicate jewellery, a textured handbag, and a soft makeup look. Avoid going head-to-toe black — the aim is to celebrate, not to mourn!

What is a Black Tie Wedding Guest Dress?
Receiving a wedding invitation with the words “black tie” can feel a little daunting — but it’s simply an opportunity to embrace more formal, polished dressing. At Style Boutique NI, we specialise in stylish occasionwear for women aged 30+, including flattering options for black tie weddings.
A black tie wedding guest dress typically means a floor-length gown or a refined midi dress made from luxurious fabrics like satin, chiffon, or velvet. The goal is to look sophisticated without outshining the bridal party. Think graceful silhouettes, thoughtful detailing, and rich colour palettes.
If you’re unsure, opt for a classic cut in navy, deep green, burgundy, or timeless black, and let your accessories add personality. Metallic heels, a beaded clutch, and statement earrings can elevate your look beautifully. For added coverage, pair your dress with a chic wrap or tailored evening coat.
At Style Boutique NI, we curate a collection of black tie appropriate dresses that combine comfort with occasion-ready style — perfect for women who want to feel confident and well-dressed at formal events.

How to Style a Slip Dress for a Wedding Guest
A slip dress can be effortlessly chic — and yes, it’s a great option for wedding guests too! It’s all in how you style it.
To style a slip dress for a wedding, start with the fabric and fit. Look for satin or silk-like finishes that drape softly and offer a touch of luxury. Midi or maxi lengths tend to feel more appropriate for formal events.
Elevate your slip dress with statement accessories — think metallic heels, a structured clutch, and gold or pearl jewellery. A soft updo or waves and a pop of colour on your lips can complete the look.
Need a little coverage? Add a cropped blazer, a lightweight shawl, or a fine knit bolero to balance the silhouette and suit the season. In cooler months, layer a tailored coat and opt for closed-toe shoes.
