Message from Cherish 

I absolutely love this petrol shade. It feels timeless but gives a softer look than classic black or navy, making it so easy to wear all year round.  Didi is one of those dresses you'll pop on when you want to feel comfortable but still look effortlessly put together. Add colourful accessories for a bold Popsy look or keep it beautifully understated.

FAQs 

Is Didi suitable work work? 

Yes. The elegant silhouette, flowing skirt and understated colour make her ideal for the office, meetings, smart casual occasions and everyday wear.

How can I style Didi throughout the year? 

Wear her with trainers or sandals in warmer months, then switch to tights, ankle boots, chunky knitwear and a long coat when the weather cools.  Petrol transitions effortlessly between seasons.

Will the relaxed fit still look smart? 

Absolutely. The dropped waist and flowing tiered skirt create graceful movement while maintaining a polished, contemporary look that's easy to dress up or down.
