All that hard work paid off! Hilary Duff shows off her svelte figure in tight sweater dress

She excitedly tweeted at the end of last month that she finally fits into her skinny jeans after tirelessly working out her post-pregnancy figure.
And Hilary Duff is making the most of her newly svelte figure.
The 25-year-old actress and singer showed off her toned curves in a tight sweater dress for a day out at a museum with baby Luca and husband Mike Comrie.

The mother-of-one was seen exiting the Museum of Modern and Contemporary Art with her eight-month-old baby Luca in her arms on Wednesday.
Meanwhile, little Luca looked adorable in a pair of jeans and a checked jacket.
Hilary has been thrilled with her steady weight loss since giving birth to her son Luca eight months ago.
And on Monday Hilary Duff was showing off her shrinking figure in a pair of size 26 skinny jeans.

'Yaaaa b******! Gabe Johns you're kickin my ass and it's paying off! Skinny jeans! lets go!' Hilary tweeted last month with a photo of the American size two (British size six) designer denim.
In June, the former child star told Us Weeklly she wanted to lose the baby weight in a healthy way: 'I think if you ask any pregnant mom, they're like 'I want my body back,' but it takes time,' she said.
But with a new TV project in the works Hilary was clearly ready to start the process as she teamed up Los Angeles-based personal trainer Gabe Johns two and a half months ago.
'Hilary and Gabe have been doing everything from boxing to two-a-day workouts incorporating wind sprints and jump roping in an effort to finally shed the baby weight,' a rep for Johns told Us Weekly.
'Hilary's been steadily dropping pounds each week.'

In addition to her workouts, the actress has been taking yoga classes and following Hollywood nutritionist Kimberly Snyder's Beauty Detox solution diet.
The star tweeted a photo of Snyder's Glowing Green Smoothie, a favourite with stars including Drew Barrymore, Black Eyed Peas singer Fergie and Magic Mike star Channing Tatum and his wife Jenna Dewan.
'A little bit of glowing green drink this morning to make everybody feel good!' Duff posted.
The actress will return to the small screen next year after signing a development deal with 20th Century Fox Television.
