FAQs
What to wear to the office in a heatwave?
In a heatwave, prioritise lightweight breathable fabrics like linen and cotton to stay cool without compromising on style. Try tailored separates like a waistcoat and wide legged trousers for a smart twist or floaty statement skirts teamed with a simple t-shirt. Button-front shirts in lightweight poplin fabrics are a great option for staying cool, while looking professional.
Keep your palette light and summery where possible, and silhouettes relaxed to allow you to feel comfortable and not overheat. If you're struggling, having a great rotation of breezy dresses will see you through the season in style, with minimal styling effort.
How to dress business casual in summer?
If your office has a slightly more formal dress code, lightweight fabrics are your friend. You won't be able to swap out formal trousers, but you can select linen fabrics to help keep you cool. Where you can, go for lighter colourways, or softer neutrals and avoid harsh black hues. If you're sticking to tailoring, wide leg trousers offer greater breathability than slim fit styles, and cotton shirt dresses are going to be your best friend in the summer months.
Keep shoes as simple and light as possible. If low-rise, white trainers are a no-go for your work environment, look to simple courts, smart leather flats, or elegant sandals to finish your look.
