Erin Deering founded her eponymous Australian fashion label, Deering, on a simple belief: that the things a woman reaches for every day should make her feel something. It's a philosophy that, it turns out, translates seamlessly to skincare. A devoted RATIONALE client, Erin collaborated with us on The Nightfall Pouch — a limited-edition gift with purchase, created to accompany The Reset Sleep Mask. We sat down with her to talk about her evening ritual, the thinking behind the design, and why you can never have too many black bags.
Her RATIONALE Journey
Erin's relationship with RATIONALE began while living overseas. In 2018, living in Monaco and surrounded by French skincare, she found the brand online. What stopped her wasn't a product. It was a system. "The structure and intention behind it really drew me in," she recalls. "I've been loyal ever since."
Today, her RATIONALE ritual remains intentionally simple. Mornings are minimal — she skips the cleanse entirely, a tip she picked up early from the brand, and goes straight to #3 The Brilliance Enriched Crème before finishing with #3 The Brilliance Tinted Serum SPF50+.
Evenings are where she slows down: a double cleanse with #4 The Nourishing Cleanser, then #5 The Refining Milk Concentrate and #6 The Rejuvenating Night Crème. Among the formulations she reaches for most, one stands out. "Nothing gives me that immediate glow quite like #3 The Brilliance Enriched Crème SPF15," she says. "It makes my skin look alive."
The Reset Sleep Mask arrived in her routine more recently—and quickly earned its place. "My first impression was that it's the perfect reset for your skin," she says. "Knowing you have this product working overnight and that you'll wake up looking incredible and feeling amazing — that's the best part. It feels like a moment of self-care, while knowing your skin is being looked after."
The Collaboration
Ask Erin what Deering and RATIONALE have in common and she doesn't hesitate. "Both brands care deeply about how a woman feels," she says. "It's luxury rooted in experience, not just appearance." This shared philosophy was the foundation for the collaboration.
For Erin, the pairing of a nighttime skincare ritual with an evening accessory felt instinctive. "A sleep mask paired with a chic pouch is such a natural meeting of our worlds," she explains.
That thinking informed every detail of The Nightfall Pouch — a piece designed to complement the evening ritual while remaining versatile enough for everyday life. "We wanted to honour the nighttime ritual," says Erin. "It's such an intimate moment in the day. Whether the pouch is carried to dinner or packed for a weekend away, it needed to feel luxurious but genuinely usable — something special, but not precious."
Crafted in jet-black satin with soft drawstrings, the pouch can be slipped over the arm as an elevated accessory. Along the edges sit Deering's signature silver starbursts — subtle details that quietly elevate the design.
"You can never have too many black bags," Erin adds. "I see this as both an evening piece and an everyday essential."
For Erin, design has always been about more than aesthetics. At Deering, every piece is created with feeling in mind. "It's the finishing touch," she says. "Whether paired with an outfit for dinner or tucked into your daily tote, I want it to make her feel polished, composed and just a little elevated."
Her greatest source of inspiration remains the women who wear her pieces. "Seeing how customers wear them — and how they feel in them — is endlessly inspiring," she says. "I design for them, and I design for myself. I'm also inspired by the depth of storytelling in the luxury space — that sense of world-building reminds me that anything is possible when you stay close to your vision."
On Mother's Day
When Mother's Day arrives, Erin's celebration is beautifully simple. As a mother of four, her perfect morning is spent together. "All my children pile into bed with me," she says. "There are handmade cards, little creations, pastries and flowers. It's simple, sweet and slightly chaotic — completely perfect.”
