The former TOWIE star was all smiles as she rocked a leather-look dress with perforated patterns on the sleeves and hem.
Lydia was joined by her mum Debbie Douglas and her little sister to toast the opening of Forest Fairytales held in Highgate Woods.
The blonde fashionista seemed to enjoy being surrounded by nature and posed for several photos both in the forest and in an open green space.
Lydia teamed her pretty dress with a sophisticated black hat, and completed her outfit with some comfy and practical black Hunter boots.
Keeping make-up to a minimum, the star looked refreshed and showed no signs that she had been partying the night before for her best friend's birthday!
Coming fully prepared for the cold weather, Lydia even wore a pair of long grey fingerless gloves.
The Bella Sorella store owner and fashion designer later popped on her grey parka coat to keep the rain at bay.
