Founder & creative director of SUMMI SUMMI.

From flight attendant to founder, Ashleigh Vallis has carved her own path with fierce determination and unapologetic style. Now at the helm of cult-favourite fashion label SUMMI SUMMI, she’s building more than just a brand. She’s creating a movement for slow, conscious fashion that’s designed for real people.
Based in the dreamy coastal town of Yamba, NSW, Ashleigh blends the effortless cool of Sydney with beachside ease to craft wearable pieces that turn heads and make people feel good. Self-taught, purpose-driven, and refreshingly down-to-earth, she’s grown SUMMI SUMMI from humble beginnings into a rising global label, all while raising two daughters, running a tight-knit team, and staying true to her values of inclusivity and sustainability.
We caught up with Ashleigh to talk about the journey so far, that unforgettable Paris campaign, the challenges of building a brand from scratch and what’s next for SUMMI SUMMI on the global stage.

Tell us a bit about yourself
I’m Ashleigh, founder of SUMMI SUMMI, mum to two young girls (and two wild dogs), living in the coastal town of Yamba, NSW. I grew up in Sydney but left uni early to travel and never looked back. Along the way I worked as a florist, bank teller, and flight attendant, where I met my partner. Eventually, we made the move to Yamba over a decade ago with my first daughter.
When I was on maternity leave, I was far from family and feeling creatively restless. That’s when the earliest seeds of SUMMI SUMMI were planted. I’ve always been someone who prefers to forge my own path, and building this brand has been just that: self-taught, passion-fuelled, and deeply personal.

What inspired you to start SUMMI SUMMI?
Before SUMMI SUMMI became what it is today, it started as a small children’s label called Tippi and Zep. I loved designing clothes for my daughters, but the business wasn’t sustainable. After a couple of years, friends began asking for adult versions of the kids’ pieces, so I gave it a go. The first drop sold out quickly, and for the first time, I made a profit.
That moment sparked a full rebrand, and I poured everything into building SUMMI SUMMI. Drawing inspiration from Sydney’s edge and Yamba’s laid-back coastal vibe, I set out to create practical, wearable pieces that still felt fun and elevated. Most of all, I wanted people to feel confident and amazing when they wore them.

You say SUMMI SUMMI is all about fashion for everyone. What does inclusivity in fashion look like to you in practice?
I’ve loved fashion and self-expression from a young age, but I’ve always found the industry a bit intimidating. With SUMMI SUMMI, I want to break down those barriers and create a space where everyone feels welcome to wear what they love, without worrying about being ‘cool’ enough.
Inclusivity, to me, isn’t just about size range or buzzwords, it’s about showing real people. That might be something as simple as re-sharing a photo of a mum in our clothes with kids at her feet or celebrating someone who’s tagged us, even if their pic isn’t picture-perfect. It’s about representing all kinds of people because fashion should be for everyone, not just a select few.
What’s been your proudest “pinch me” moment with SUMMI SUMMI so far?
There have been many so it’s hard to pick just one. I would say the most recent has been flying to Paris with the SUMMI SUMMI team to shoot a campaign. We were under the Eiffel Tower, and I thought, “Wow, look how far the university dropout has come”.

SUMMI SUMMI walks the walk when it comes to sustainability. Why was it so important to you to go slow and stay conscious?
Going slow and staying conscious was important to me because I’ve seen how damaging fast fashion can be. I didn’t want to be part of that cycle. While we don’t claim to be fully sustainable (because true sustainability is more about wearing pre-worn or vintage), we do everything we can to minimise our impact. That means producing in small runs, avoiding plastic, using compostable packaging, and donating any leftover stock. It’s about making thoughtful choices and being transparent, not perfect.
What advice would you give other women wanting to build something of their own, especially with zero formal training?
I think the most important thing is to never give up. If you believe in what you’re building, don’t let a lack of formal training hold you back. Most success comes from persistence, not perfection. It won’t happen overnight, and there will be setbacks, but resilience is everything. Learn from people who know more than you, find a mentor, and when you can, hire those who excel in areas you don’t. Most importantly, surround yourself with positive, supportive people, it makes all the difference.

What’s your current go-to SUMMI SUMMI piece on repeat?
It’s actually a crazy red lined leather trench coat that we sampled last year that didn’t go into production. I’m forever wearing the rejected samples.
You’ve got 5 minutes to get dressed for a surprise dinner invite. What are you throwing on?
Any of our Siren dresses. It is such a sexy fit on all shapes and sizes. It’s cut on the bias and feels like silky butter to touch.
Who are some of your personal fashion icons or creative inspirations?
I love Paris Wycherly, Maxine Wylde, and just European girls in general.
What’s next for SUMMI SUMMI?
Growing further into the US market. We already have our foot in the door with some major accounts, but that’s just the beginning!
