A day after wowing in a cute baroque printed tunic dress from her Bella Sorella store, the ex-TOWIE star stepped out in London on Wednesday evening (19 June) looking rather ethereal in this flowing white number.
We're loving the pop of colour too with the gorgeous green arm candy.
As Lydia was out having fun and hobnobbing with stars including Amelia Lily, Dionne Bromfield and Emily Atack, it appears she missed last night's TOWIE episode featuring her return!
The fashion designer, who bowed out of the ITV2 show last year, made a one-off return to The Only Way Is Essex to offer best friend Lucy Mecklenburgh some words of advice following the surprise news that Dan Osborne's ex-girlfriend is expecting a baby.
Lucy had been on dates with Dan since they hooked up in Marbella. "At the end of the day, this is a sign," suggested Lydia. "Just stay friends."
Lydia, who is currently single, also wondered if she and Lucy both fall in love "too quickly", saying: "I only have to see someone on the bus and fall in love with them. We have to distinguish between love and lust."
Wise words, Lydia.
