From AM to PM: Imogen Thomas swapped her errand-running attire for a sexy black dress for a night on the town
Even when she's out running errands Imogen Thomas still looks chicer than most.
However, it was a dazzling transformation for the glamour model when she ditched the jeans for a stunning little black dress to attend a star-studded party last night.
Imogen, 28, was snapped out and about in north London yesterday sorting some mail out at the post office, doing a bit of shopping and visiting the bank.
In red skinny jeans, a black vest top and multi-coloured Louboutin heels, not typical attire for dashing about town.
But it was a stunning transformation a few hours later when she ditched the day wear for the black dress, which she got from Debra at Chigwell, to attend a party at London's Oxo Tower.
She was one of the celebrity guests at the bash which was held to promote telecommunications company O2's Priority service for their customers.

The former Big Brother contestant has just returned from a trip to Los Angeles, her tanned skin and relaxed demeanour suggesting that she had had a great time.
It proved to be a busy day for her as she took to her Twitter page and wrote: 'Bank, Post office, Acting class, then party! In that order!
'looking forward 2 having a drink. Im always driving!!! Dance the night away..;-)'
'I'm always driving!' Imogen moaned on Twitter that she is always in her car
She was out for the night with her friend Sam Seller, bit after she arrived on her own, she realised she had sent him to the wrong venue.
She tweeted her apology: 'I can't believe I sent my friend @samseller to the O2 and the party is in town!!! Hahaha!! Sorryyyyyyyyyyy'
But he found her in the end and they were snapped leaving together at the end of the night.
