Kate Middleton wore a coat that's perfect for fall while visiting students in Derby, England, on Tuesday.

The Duchess of Cambridge arrived at the University of Derby wearing a Massimo Dutti $349 beige checked wool coat, black pants, and a $179 cashmere crewneck sweater in aquamarine, also from Massimo Dutti.

Middleton also wore a $19 floral face mask from the British brand Amaia. She previously wore a similar style from the same brand, and while the mask is currently sold out on the Amaia website, other sites sell similar floral-print masks.

The duchess completed her look with a $127 Personalized Gold Three Layered Disc Necklace from All The Falling Stars. Each disc on the necklace has the first initial of each of her three children: "G" for Prince George, "C" for Princess Charlotte, and "L" for Prince Louis.

Middleton has another necklace that pays tribute to her children. In August, she wore a $1,340 Daniella Draper necklace that features a single gold disc engraved with her kids' first initials.

Kensington Palace shared more photos of the duchess at the University of Derby on its official Instagram page on Tuesday.

Ahead of #WorldMentalHealthDay this Saturday, The Duchess of Cambridge visited students at @DerbyUni to hear how initiatives including peer mentoring are supporting students’ mental health during the pandemic. @studentmindsorg, the UK’s student mental health charity, say that the coronavirus pandemic has exacerbated existing challenges facing student mental health, in addition to creating new ones. Even before the onset of COVID-19, both the severity and prevalence of common mental health conditions experienced by young adults was on the increase. However, like the sports societies and nursing students here at Derby, universities are continuing to explore new ways to support their wellbeing. Students across England and Wales now have access to trusted support through the coronavirus pandemic via @studentmindsorg Student Space, a programme that helps students to find support that is available locally at their university, in addition to providing online resources and direct support by phone and text. The 24/7 text support available via Student Space is delivered in partnership with @GiveUsAShoutInsta, a legacy initiative from the Heads Together campaign and was incubated by The Royal Foundation ahead of its launch in 2019.

Middleton is known for sporting stylish coats like the one she wore on Tuesday.

She wore a baby-blue coat from maternity designer Séraphine while on a visit to Kings College in London in 2018.

Also in 2018, Middleton wore a knee-length, bright-red statement coat from Boden while visiting Great Ormond Street Hospital in London.

While on a tour of Ireland in March, she wore a structured green Catherine Walker coat that fell just below the knee.

Representatives for the Duke and Duchess of Cambridge did not immediately respond to Insider's request for comment.
