The Celebrity Big Brother star told Heat that her dress-sense has matured since the couple parted.
Heaton said: "I feel like I've grown up dramatically since I left my husband. I want different looks out of life now, rather than getting my a**e out.
"I've grown up image-wise, clothes-wise. For six years I presumed showing flesh was sexy and turning up to events wearing very little would get me in the papers."
She added: "And it did, but for the wrong reasons. It's great to feel girly and pretty and not have to show flesh."
Heaton also revealed that she loved the "glamorous" photoshoot makeover she received from How To Look Good Naked's Gok Wan.
