Melissa McCarthy wants to ''empower'' women with her clothing collection.

The 'Spy' star - who is launching her own plus size apparel line Melissa McCarthy Seven7 with Sunrise Brands - wants to encourage those who buy her garments to feel confident in their appearance no matter what.

She said: ''I want women to get dressed every day and feel good about themselves. I don't care what it is, if it's dyeing your hair blue, if it's a sweater, whatever you want to do, if it makes you feel good and empowered, I stand behind it 100 percent.

''And if I can be a little tiny block on that wall, I'd be proud of that.''

When it comes to her own style, the 44-year-old star likes to adapt her look to her mood and hopes the line will allow other women to do the same.

She explained to PEOPLE: ''I just don't believe in a uniform.

''I think if people have it and they love it, great, but I think people get into a rut and I've always been someone who gets a kick out of dressing.

''I like vintage, I can never pick one style. I like a little blouse that looks great with a pencil skirt but then the next day I can wear it with ripped jeans and boots.

''I'm trying to give women a closet that gives them some variety.''

Melissa - who has two young daughters, Vivian and Georgette, with her husband Ben Falcone - was happy to share her favourite piece from the line and chose a cute cat print sweater which was designed by one of her girls.

She said: ''There's a sweater with a cat drawn on it that's saying 'Meow,' and my daughter drew it and it just kind of breaks my heart.

''I'm such a dorky mom, I get choked up about the dumbest things. Not that that's dumb. It's just that she's very creative, she loves to draw.''
