The fashion rules might be strictly 'whites only' at tennis' most famous tournament, but Serena proves that you can still push the boundaries with this fabulous pop art manicure...
Serena first showcased her talons at the pre-Wimbledon party at the Kensington Roof Gardens in London last week (21 June).
The word 'Pow' was emblazoned across her nails – a warning to her fellow players of the strength of Serena's tennis skills do we reckon?
We'd certainly be scared of facing her strong, speedy serve, that's for sure!
Serena carried on the theme of her 'pow' nails by wearing a similar manicure for her opening match against Mandy Minella on Tuesday.
And she whooped the poor Luxembourg player 6-1, 6-3!
If you fancy channelling a bit of Serena nail action, try some peel-off nail wraps as an easy way to copy her look.
We love Elegant Touch Little Mix Jesy Nail Wraps, £6, asos.com and Models Own WAH Nails Pow Wraps, £7, boots.com which both make that 'I mean business' statement perfectly!
