Pattern Hacking
Create Custom-Fitted Patterns — the Smart, Professional Way
Every couture project starts with a pattern — but only the best dressmakers know how to make it their own.
This masterclass unlocks the secrets of Pattern Hacking, a professional method that allows you to create perfectly fitted garments using a tested Master Pattern as your base.
Instead of redrawing from scratch, you’ll learn to adapt, reshape, and resize existing patterns for any body type or design idea — saving hours of work and achieving flawless results every time.

I made my own custom amazing wedding dress! The lessons were very easy to follow as everything is explained step by step.
Absolutely love this sewing academy! I signed up for a 1-year subscription two years ago and loved it so much that I just upgraded to lifetime access. The lessons are super clear, the techniques and patterns actually work (no frustration with trial and error!), and I’ve seen real improvement in my sewing from day one. What really makes it special is the community—so helpful and supportive. It’s honestly been the biggest boost to my skills. If you're into dressmaking or want to get better at sewing, this course is 100% worth it!

I was delighted with my first class at Dressmaking Academy. I very much appreciated Tatiana's expertise, and found the corset direction and explanation easy to follow. I feel I am on my way to proficiency and professionalism! My one challenge was compiling the right materials. I economized, as it was my first lesson. I feel the corset would have come out better had I used exact materials. Lesson learned.

I made the bustier using the free pattern, smallest size. Making it was occasionally challenging because I was using materials that were not familiar to me, and I had no experience sewing lingerie or anything similar, yet I was able to figure it out. The bustier is a beautiful garment, but I am too modest to wear such sheer clothing.
