The former Spice Girl debuted her new autumn/winter collection at New York Fashion Week. Speaking to Grazia, she revealed that her family's "everyday life" had inspired a number of the items.
The 37-year-old revealed that David's beanie hat and her son Romeo's baseball outfit had been among the influences.
Joking about her husband, who recently launched his H&M Bodywear range, Victoria said: "David actually now realises that I have a job. I don't think he knew what I did."
The new mother, who was joined at the show by 7-month old daughter Harper Seven for the first time, added: "I'm designing what I want to wear, and what feels right to me."
Grazia's Big Fashion Issue will be available next Tuesday (February 21).
