The Duchess of Cambridge has been hard at work this week. On Wednesday morning in London, she stepped out in her most casual ensemble yet. Kate Middleton visited LEYF Stockwell Gardens Nursery and Pre-School in the city and paired a bright teal coat with a white blouse, black skinny jeans, and black ankle boots. She wore her hair down and accessorized with delicate dangle earrings.

Inside the store, Kate served breakfast with her children:

According to Who What Wear, Kate wore a top (unfortunately sold out) by Parisian high-street brand Sézane. (opens in new tab) Her teal coat has not been ID'd, but this jigsaw wool number is very similar:

Kate appeared today to promote the "5 Big Questions" survey (opens in new tab) launched earlier this month for British parents. Kensington Palace announced that the results of the survey will guide Kate's work in early childhood development and mental health

and that Kate will be in Birmingham, England, to promote the survey. She first visited parents and children in Birmingham and then met more parents and children in Cardiff. The Royal Press Corps announced that Kate was touring the UK for 24 hours, with stops in London and Surrey
