What a transformation! Model and The Block contestant Elyse Knowles looks almost unrecognisable after trading work boots for a designer outfit at the Myer Spring Social

She's recently traded the catwalk for a building site, adding a down-to-earth look to go along with her new occupation.

But on Thursday night bikini model and The Block contestant Elyse Knowles went back to her glamorous roots, putting in a fashionable appearance at the Myer Spring Social in Sydney.

Gone were her work boots and tracksuit, with the blonde beauty instead wearing a striking cocktail dress and full makeup.

Elyse rubbed shoulders with the A-list at the department store event, with other guests including Jennifer Hawkins, Jodi Anasta and Natalie Roser.

The blonde beauty wore a stylish cocktail dress by Asilio , pairing it with strappy gold stilettos and a $2,000 YSL handbag. 

Sporting a golden tan, she accentuated her natural beauty with a strong smoky eye and bold red lipstick.

The model isn't afraid to get dirty on the reality TV show, regularly sporting blotches of paint on her makeup free skin and messy hair.

She also wasn't seen in designer outfits while filming, instead opting to wear work gear and old tracksuits.

While she skipped her usual glamorous grooming and clothing for The Block, Elyse is certainly not one to compromise on exercise and diet. 

She told  Body + Soul in May that she gets up at 5.15am most days of the week to go to the gym.

'I work on my body every day. I am constantly working out, watching what I eat and drink, and making sure my brain is healthy too,' Elyse said.
