When she's not inspiring us to hit the gym and eat right, Roz Purcell is posing up a storm in  a series of stunning outfits over on Instagram. 

Last night was no exception, as the fitness influencer and model celebrated her birthday at The Drury Buildings, where iconic online brand Nasty Gal was showcasing their new A/W collection. 

September dressing can be tricky, but Roz's Nasty Gal ensemble was the ideal way to incorporate autumnal trends into a still summery look.

Plaid is always in for Autumn, but if you're not ready to drown yourself in heavy layers of it, Roz's Dionne Plaid Dress is the way to go. 

Currently on sale for €24.00 over on Nasty Gal, the checked mini dress is the perfect transitional piece. 

Rounding off the look, Roz added her black Miu Miu Club Matelassé bag slung around her waist, a favourite of hers if her Instagram is anything to go by, and kept the Autumnal vibe going with a pair of subtle sock booties.

Her gorgeous sister Rachel rocked an off-duty model look, pairing black skinny jeans with a casual denim jacket and a lace up crop top. 

Made in Chelsea stars Frankie Gaff and Jessica Anne Woodley, along with fashion trendsetters and influencers Chloe Lloyd, Cairo Dwek and Yasmine Chanel flew into Dublin for the soiree.
