A mini dress with suspender stockings probably isn't the ideal outfit for dining with the parents.

So after sitting across from her daughter's exposed thighs all night during a weekend get together, perhaps Kathy Hilton had a quiet word in Paris' ear.

Because when the family ventured out for Kathy's birthday meal last night, the reality star was wearing a far more demure, girly party dress that looks like just the thing a mother would choose for her daughter.

And in fact, she did. The pale pink tulle and lace confection is actually a design from Mrs Hilton's dress collection.

The family matriarch's designs are sold at Nordstrom department stores and retails between 300 – 400.

Paris, 31, teamed the feminine frock with a pink clutch, nude heels and soft make-up.
