Primark Cotton Shirred Tiered Midi Dress
Cotton is a fantastic fabric to wear in the summer: it’s breathable and helps keep you cool.
While this sleeveless dress might not be appropriate for all offices, it can easily be paired with a thin shirt or cardigan to keep your shoulders covered and protect you from the air-con chill.

M&S Ruched Maxi Waisted Dress with Linen
A busy day at the office can involve long stretches of sitting at your desk, so comfort is key.
This dress has a drop shoulder and an adjustable waist — you might have it loose and flowing when sitting at your desk, then tighter and cinched when heading out for after-work drinks.

H&M Linen-Blend Shirt Dress
A linen shirt dress looks the part in most office environments. When properly ironed, and paired with a leather belt and leather flats or pumps, it’ll look clean and professional.
This one has drop shoulders (look for these if you’re worried about sweat patches) and elbow-length sleeves and is available in blue, black and cream-striped options. The material is a cotton and linen blend, meaning it’s still cooling but not as prone to creasing as 100% linen.

Pair it with a pair of trainers or ballet flats and carry a denim jacket or light cardigan to brave the office air-con.
