Pretty, floaty and feminine, this oversized polka dot print dress ticks all the boxes when it comes to occasionwear. A strong choice for what to wear to a christening, wedding or even Wimbledon this summer, add a tailored white blazer to give this design a more relaxed feel. Available up to a size 26, this size inclusive design can be worn year after year.
Phase Eight is known for its tapework embellishment and this knee-length design uses the technique to perfection. Creating an optical illusion, through a central panel, the tapework has been added in an hourglass shape, which narrows your waistline, and adds curves. The monochrome colour palette is a timeless classic, ensuring this shift dress won't date can can be taken out and dressed up for all occasions.
"I’m normally a sundress kind of girl, but I have recently embraced wide-leg trousers and I’m enjoying the easy-breezy feel they bring to an outfit. This pair is definitely at the top of my summer shopping list. I love the fruity holiday-esque print, and the swishy fabric combined with a high cut, belted waist makes them flattering too. There’s a matching shirt available, but I think I will keep it simple and team these with a plain tee and chunky sandals," says style editor Matilda Stanley.
Available up to a size 26, this chic jumpsuit is ideal an occasionwear winner. The wide leg offers great breathability, as well as creating a flattering silhouette, narrowing your waistline and balancing busts and shoulders. The sweet neck-tie detail adds to the feminine feel. Team with heeled sandals, or espadrille wedges to seal that summery feel.
A great all rounder, this flattering jumpsuit can be dressed down with trainers white trainers, or styled up as a chic alternative to the best wedding guest dresses. The crossover front is flattering across the bust, while the tie side draws the eye up and in, creating a cinched in middle. The fluted sleeve is ideal for added sun coverage, great for outdoor events. Available in mainline or petite collections
Phase Eight is this year's official style partner of Goodwood Race Course, and this dress forms part of that special collection. Ideal for what to wear to the races, polka dots remain a huge summer trend and this retro-inspired design features a feminine front frill, three-quarter sleeves and a midi hem length for unparalleled elegance.
Super glam, feel like a total A-lister in this caped design. The jewelled neckline takes care of the added sparkle, although some studded diamond earrings would offset this look beautifully. Make sure your shoes are embellishment-free, so that nothing catches on the delicate fabric of the dress. If you're looking for the best mother of the groom dresses - consider this one.
This central style ruching was prevalent in the spring/summer 2025 collection by Victoria Beckham, which featured a figure flattering gather down the centre panel. Echoing this style, this jersey iteration in a dark navy comes in mainline and petite and is a great dress for gently skimming a midriff, while still enhancing your natural silhouette.
Ideal for what to wear in the heat, this beautiful swishy skirt will have you twirling through the summer in style. For everyday wear, pair this pretty piece with a classic white t-shirt and a denim jacket. To up-style it for an event, add wedges, a crisp white shirt and a statement necklace in the neckline to up the glam factor.
