Before you invest in developing a collection, you need to know what you’re building, why it belongs in the market, how it should be resolved and whether the direction is strong enough to take into sampling and production. That’s where we start.

Why I started By Phases
Why I started By Phases
Hey! I'm Zinnia :)
I’m a fashion designer and the co-founder of
By Phases. I’ve spent nearly a decade working across fashion design, garment technical development, pattern making, sampling and production.
Today, I help founders take the ideas they have in their head and turn them into clear, cohesive and technically resolved womenswear collections.
From defining the initial direction and developing each design, through to garment technical development, tech packs, sampling and production, I’m here to help turn those ideas into production-ready designs that can move forward confidently towards launch.

Testimonials
Working with Zinnia has been really smooth and easy. She quickly got the vibe of THE KRIPT and turned it into
strong designs that felt right for our brand. Her way of working is clear and organized, which made the
whole process much faster. We’re looking forward to creating more collections with her.

I had a wonderful experience working with Zinnia and would highly recommend her. From the very beginning, Zinnia was incredibly helpful, knowledgeable, and patient throughout the entire design process. She provided multiple design concepts for me to choose from, which made it much easier to refine my vision while still feeling like the collection was uniquely mine.
Zinnia also helped guide the overall direction of my brand and offered thoughtful, professional advice along the way. One thing I really appreciated was that she didn’t just recommend fabrics, she took the time to explain why she believed certain fabrics would work best for each garment, considering the silhouette, structure, quality, and overall aesthetic. That level of knowledge gave me a lot of confidence in the decisions we
were making.
Communication was always clear,
and I genuinely felt supported throughout the process. I learned so much from working with Zinnia, and it’s obvious she has a fantastic understanding of fashion design and garment development.
I’ll definitely be coming back for future collections and look forward to working with Zinnia again. Thank you for helping bring my vision to life!

I just wanted to say how genuinely impressed I am with the tech pack. I’ve worked with quite a few people within this field and received a number of tech packs over the years, and I can confidently say this is the best I’ve received. The level of detail, the pattern pieces, annotations and overall presentation are incredibly thorough and well thought out.
I also really appreciated you taking the time to provide the walkthrough video and voiceover. As I’m much more familiar with working from PDF tech packs than Excel, it made such a difference in helping me understand how to navigate and use the files properly. It was extremely informative and helpful.
You’ve been so professional, helpful and efficient throughout the entire process, and I’m honestly so pleased with the work. I really hope we can build a long-term working relationship between myself/HALIA and you/ByPhases, as I would absolutely love to continue working together
on future projects.

I’m beyond impressed with the work from Zinnia. She was incredibly responsive, super kind and made the entire process seamless. Every question was met with patience and clarity, and she truly brought my vision to life. Her talent is undeniable - she has a remarkable ability to translate ideas into something even better than imagined. I couldn’t recommend her more and hope for further collaborations.”
“It has gone so well and couldn’t have done it without you! I’ve heard so many people say they have to spend quite a lot of money on samples on multiple rounds but it was one round and the manufacturer has just made small measurement adjustments.”
“I’ll definitely need to re-engage for another product / collection very soon … and every one after that !!”
