Yesterday afternoon, RTÉ2fm presenter Jennifer Zamparelli posted an unexpected tweet about her fashion goal for 2020, and we couldn't be happier to see it.

The 39-year-old, who is known for her chic yet accessible style, revealed that she was joining the sustainable fashion movement and has pledged to avoid the high-street at all cost:

"I'm posting this for one reason and that is to put positive pressure on myself. I will not buy a stitch of clothing this year. I'm gonna reuse, borrow and stay out of Penny's. If you see me skulking around Zara, you have full permission to slap me."

On Dancing with the Stars, with the help of stylist Fiona Fagan, the host stuns in various high-end designs including Solace London, Talbot Runhof, and Self-Portrait. This year, however, will be a little different.

Speaking about her work wardrobe with designer Brendan Courtney on Twitter, Jen explained that she was allowed to keep her outfits from last season - all of which she later donated - whereas, this year, she plans to borrow or re-work her outfits.

"Everything I've worn so far has been sent back with the sweat and tears of x contestants on it," she joked.

In fact, we have already seen the incredible handy work of Jen's team in action. Last week, with the help of costume designer Louise Lawlor, and under the vision of stylist Fiona Fagan, the host transformed her sparkly mini-dress - which she originally wore in week 10 of 2019 - into a glitzy one-shouldered number.

Posting the photo of her revamped look on Instagram, the TV presenter said she "really wanted to rework a dress from last year," and with good reason.

According to Oxfam Ireland, 225,000 tonnes of clothing ends up in a landfill in Ireland every year. Not only is this a waste of water and energy but it simply isn't sustainable.

If we were betting women, we here at RTÉ LifeStyle would put money on Jen's new sustainability goal being influenced by her friend and co-worker, Tara Stewart.

The ultra-trendy DJ is a sustainable-fashion advocate who has hosted an entire podcast series dedicated to the subject of fast fashion. Listen back to Dirty Laundry here.

Her Instagram feed is full of incredible charity-shops finds, revamped pieces, and hand-painted and tailored alterations (she even signed up to a sewing class).

If you're looking for even information or inspiration in Ireland, you need only look to Karen O'Mahony of Rag Order, Tipperary woman Edel Lyons of Rag Revolution, students Victoria Latham Brunton, Sadhbh Whitty and Meg O'Doherty of Glas Fashion or Taz Kelleher and Geraldine Carton of Sustainable Fashion Dublin.

Following the tweet, Jen joined Ray D'Arcy on RTÉ Radio 1 to discuss her 2020 resolution. Listen back above.
