TikTok user Aoife O'Farrell - who boasts 200,000 followers - posted a video of her modelling a similar knit, which she branded a wardrobe 'essential'.
The fashion content creator captioned the post: 'Winter essentials: a When Harry Met Sally knit jumper.'.

In the video, Dominick is wearing a near-identical jumper, blue jeans and trainers - as he joked: 'It's that time of year...'.
