Get wedged with espadrilles like Isla Fisher

For Reese Witherspoon's 40th birthday party, all the big names were in attendance. From Isla Fisher to Taylor Swift and Jennifer Aniston, all her gal pals showed up to help celebrate.

Actress Isla arrived looking all white in this ensemble. A lace blouse and tie-front shorts were paired together and she finished the look off with lace up wedges and added a splash of color with the help of her yellow striped wristlet.

Wedges are always a comfortable footwear choice. They allow you to extend those pins and still party the night away without sore feet and they're generally easier to walk in than stilettos too.

Isla's pair are by Tory Burch but are now sold out. Why not shop other shoes by the designer by clicking through to Farfetch (right)?

With a big smile plastered on her face, Isla was seen carefully navigating her steps as she called it a night following the star-studded bash.

Journeying through the street, Fisher appeared to try go incognito as she hid her behind a large feathered purple masquerade mask.

Cutting a slightly dishevelled figure, the 40-year-old tresses showed off just how much fun she had at the soirée as several strands were out of place.

For the party, Isla did well to stand out from the crowd as she rocked a white outfit which worked well in contrast to her fiery locks.

Showing off her slender pins, Fisher wore a high neck lace detail playsuit which featured a tailored shorts and a belt fashioned in a bow.

Adding height to the ensemble, the mother-of-three stood tall in peep toe wedges and she clutched a striped bag.
