Formal Dresses 

Where to buy a fancy formal dress online in UK?

The Formal Dresses edit for women online at Showpo is made for every formal event moment that calls for a little extra effort, the big nights, the milestone dinners, and every “wow, you look amazing” moment in between. Whether you’re heading to a black-tie wedding, an evening ball, your Year 10 or Year 12 formal, your graduation, or even just a fancy dinner that got a little more dressy than expected, these unique women's pieces bring polish without trying too hard.

What is the formal dress code? For a wedding? How to dress for a semi-formal event?

If drama’s your thing, you’ll fall for our maxi gowns, sweeping silhouettes, luxe satin, and chiffon that moves beautifully under the gala lights. Want that perfect in-between for a party? Semi-formal Midis strike the balance between timeless and modern, made for the girl who likes a little structure with her sparkle. And when it’s time to go all out for a wedding, reach for our elegant satin or sequin formal dresses, they catch the light (and attention) from every angle. You’ll find all kinds of cuts here: halternecks, off-the-shoulder moments, strapless styles, and those one-shoulder looks that show just the right bit of skin. The colours are just as good: soft champagne, blush pink tones, deep emerald green, and classic navy blue. They all hit different once the lights go down; our unique formal and semi-formal dresses are made for evenings out.

How to style a formal dress? How to accessorise a formal dress? What to wear over a formal dress when its cold? 

Styling for an evening gala? Easy. Grab a pair of barely-there heels from our collection and a sparkly clutch or chic bag that fits the essentials: phone, lip, cards, done. Put on gold jewellery pieces if you want that warm glow; silver if you feel like looking sharper. For hair, it’s totally up to the vibe you’re going for. Soft waves give easy and romantic, and a slick bun is perfect when you’re into that clean, polished look. A touch of highlight on your cheekbones never hurts, and a red lip if you’re in the mood to go bold. Cold outside? No stress. Throw on a tailored blazer, faux fur coat or jacket, or an elegant shawl to stay warm without ruining the vibe. Structured outerwear keeps the look formal, elegant, polished, and event-ready, even when the temperature drops.

Is there free shipping in the UK? Does Showpo offer plus-size options?

Our UK girls get free shipping for carts over €150. See our shipping page for more information. Not sure about sizing? Our Size Guide is super easy to follow, and if it’s not quite right, our Returns Policy has your back, no stress. We also carry sizes 0-16, including plus sizes, so that all girls can find their perfect dress. Formal dresses don’t need to feel stiff; it’s whatever makes you feel good. You should feel like yourself, just dialled up a bit. Pick the clothes or dress you can’t stop thinking about, throw on your heels, and have a gorgeous night.
