When it comes to effortlessly cool style, Sienna Miller is an expert. The star always manages to make even the simplest of ensembles look chic, and it’s often down to her savvy choice of accessories.
A perfect example of her wardrobe know-how is this shirt and denim combination, which she wore last August. Sienna was spotted in London rocking a neutral shirt, which she had tucked into her blue, wide-leg jeans. It was an understated and straightforward pairing, but she then upgraded her low-key separates by adding the Gucci Giglio Large Tote Bag and a pair of shiny red Miu Miu clogs. Her colourful designer pieces were enough to lift her look and added a high-fashion spin while still being very wearable, and it’s an aesthetic we will be recreating on repeat as we start to think about early autumn outfit ideas.

Sienna really did nail it with her bag and shoe choices, and her bag in particular grabbed our attention. The Gucci Giglio Large Tote bag has been a firm favourite with the fashion set over the years, and the red and green stripe detail works well to lift an outfit. Whether you invest in the same luxury piece or a high street doppelganger, a neutrally-toned, patterned bag will add some interest to plainer items in your closet, and the larger size will be ideal for both work and a busy weekend.
This outfit might be a year old, but Sienna was ahead of the curve when it came to footwear, as bold red shoes have been a huge spring/summer fashion trend of 2026, and it's an aesthetic that looks set to stay into next season. Take note from the star and opt for clogs or sandals right now, and then try a pair of your most comfortable trainers in a berry hue once the weather starts to cool.
You really don't need to go all out with print and colour when it comes to looking stylish - the right finishing touches can completely upgrade your autumn capsule wardrobe with minimal effort.
