Finding the perfect wedding guest dress can be a joyful experience — but if you wear a plus size, it can sometimes feel like a challenge. So many high-street options fall short when it comes to flattering fit, quality fabrics, and special details. The good news? At Style Boutique NI, we believe every woman deserves to feel confident and comfortable, whatever the occasion.
Whether you’re attending a spring ceremony, a formal black-tie wedding, or a relaxed countryside reception, our range of wedding guest dresses is thoughtfully curated for women aged 35+ — with inclusive sizing, flattering silhouettes, and standout designs.
Wedding Style Without the Struggle
You shouldn’t have to compromise on style or comfort because of size. That’s why Style Boutique NI hand-picks dresses that focus on real fit, wearable shapes, and thoughtful details like sleeves, stretch fabrics, and wrap or ruched silhouettes that offer structure and support in all the right places.
The TIA Ruched Dress with Bell Sleeves is a fantastic example. Its ruched waist helps define your shape, while the flowing bell sleeves and colourful abstract print bring a fresh, fun vibe to any celebration. It’s a flattering midi-length style that’s ideal for both day and evening weddings — and it’s available in a generous range of sizes.
Occasion-Ready Dresses with Real Impact
Looking for something that feels dressy enough for a more formal setting? The Hope & Ivy Puff Feather Trim Flutter Sleeve Midi Dress ticks every box. The feather trim adds a unique touch, while the embellished bows and flutter sleeves create shape without adding bulk. The black base is timeless, while the details bring just enough drama for a black-tie or evening wedding.
Prefer something with movement and flow? The Hope & Ivy Blouson Sleeve Floral Maxi Wrap Dress is universally flattering. The wrap design is adjustable at the waist and the blouson sleeves add soft structure to the arms and shoulders. The floral print is ideal for year-round styling — wear it with heels and a clutch in summer, or layer with a smart coat and ankle boots in cooler months.
