The comments were made while Bien appeared on BBC Breakfast.
While watching the show the Location, Location, Location, presenter tweeted: “Finance woman on BBC breakfast clearly came directly from a night out and it’s debatable whether that’s a skirt of not -hardtotakeserioulsy.”
Bien later tweeted: “No, as a mother of 18-moth old, no nights out and I was wearing a dress, not a skirt.”
To which Allsop replied: “It’s only fair to give right of reply!”
Allsopp later added: “For the record, I’m no saint, I do think, says and tweet mean things and I am as capable as anyone of hypocrisy, and my spelling is dodgy.”
One Bien supporter tweeted: “I find it really sad that women are so critical of each other re: appearance. It just wouldn’t happen with men.”
Rob Jupp, managing director of Brightstar Financial also weighed into the debate, he tweeted: “Just caught the end of this and I think this is scandalous that such a comment has been made. You are a wonderful ambassador for us all and I saw you this morning and thought you looked great!.”
Drew Wotherspoon, director of marketing at John Charcol also tweeted: “I’ll send Ray in a dress next time so she can really have something to talk about…ridiculous.”
