Blue Denim Tie Front Puff Sleeve Midi Dress

For our full sizing information and measurement charts, read our size guide. To make sure you find the best fit, measure your bust, hips and waist and compare to our clothing size chart.

To measure your bust, wrap the tape measure around the fullest part of the bust and shoulder blades. The tape measure should sit close to the body but not too tight.

To measure your waist, wrap the tape measure around your natural waistline, between the bottom of your ribs and the top of your hips, just above your belly button. The tape measure should sit close to the body, but not too tight. To get the most realistic measurement, breathe out and measure your waist after you exhale.

To measure your hips, stand with your feet together and wrap the tape measure around the widest part of your hips and bum. The tape measure should sit close to the body, but not too tight.

All clothing sizes on our UK and IE websites are shown in UK sizes. If you're shopping on our US website sizes will be shown in US sizes. For other size conversions, check your usual size against our international size chart.

Look inside your OB clothing and you’ll find a small care label with UK and EU-regulated symbols for washing, drying and caring for your clothes. You should always check the care label before washing your clothes – this will help to keep them in good condition for as long as possible. Read our washing guide for advice on hand-washing, machine washing and a handy list of common wash care symbols.

At OB, we design with both creativity and quality in mind, and we want your clothing to live on for years to come. With this in mind, we've teamed up with Reskinned, who resell, repurpose, or recycle pre-loved clothing and recondition it for another happy customer. With Reskinned takeback, you can trade in the Oliver Bonas clothing and accessories that no longer have a place in your wardrobe and receive up to £25 off your next Oliver Bonas online order when you donate. Your items will be refreshed, revived and resold in our pre-loved shop, where you can find items at lower prices, saving money and reducing waste.

We want everything to have a second chance, so pieces that cannot be reconditioned for resale will be repurposed, upcycled or responsibly recycled to ensure nothing goes to landfill.

From our designers to our stylists, the OB Fashion Team is an inventive and creatively inspired collective, working together to design, develop and style our clothing. They love nothing more than experimenting with pattern, colour and silhouettes and sourcing planet-conscious materials to create original outfits that are made to last. All our clothing prints are designed in the OB creative studios using digital and hand-drawn techniques.

The OB Fashion Team's trained designers, buyers and garment technologists work collaboratively with our suppliers to select lower-impact materials where possible, while still maintaining comfort and durability in designs our customers love. 

You can find the material breakdown of a specific clothing product on the individual product page. Check our care guide for in-depth care, washing and repair advice from our team, as well as specific material care guides to help make your item last.
