Kirkwood tweeted after eagle-eyed viewers commented on social media.
She wrote: “For those asking, lovely @louiseminchin and I didn’t deliberately wear the same dress (in different colours) this morning - pure coincidence.”
Minchin added: “A late change on my part!” and also tweeted: “So, I changed at 5 to 6 so I wasn’t wearing the same as @stephbreakfast and managed to put on the same dress as @carolkirkwood! #dressclash”.
Kirkwood sported the v-neck dress with a pink top and purple bottom half, while Minchin’s frock had two hues of blue, a lighter one at the top and darker one at the bottom.
The dress, from Diva Catwalk, is called Nadia Colour Block Sleeved Dress and costs £115.
Viewers didn’t seem to mind the fashion clash, with one tweeting: “#bbc breakfast @louiseminchin and @carolkirkwood look fab in their matching dresses today.”
