Get Started


This is a look from the Spring/Summer 2017 show. It's a very ornate, embroidered, double-face wool jacket over a lace dress. And what we did was we drew a print or a pattern onto a muslin. And then, again, it was sent to embroiderer in Italy who rendered the drawing in various sizes of clear sequins and paillettes to look almost like a watercolor drawing. So by layering the sizes and the colors of the paillettes it created this sort of almost painted look to the embroidery. And of course, the skills and the techniques of the embroiderers are so extraordinary. And it's one of the reasons why we love to do embroideries. So we gave them a painting. And we said, how can you duplicate that out of these plastic sequins and paillettes? And they did a series of trials and they showed it to us. And then we, of course, corrected it and made comments. And then that became the embroidery for this particular jacket, or coat, as it were. And this was the collection which I collaborated with artist Julie Verhoeven, who I've worked with many times before. And she did not do this print. But what she did do was the drawing of the vacuum cleaner that became this lace dress. So this is a technique called intarsia. And what intarsia is is when the fabric is not appliqued or placed on top of another fabric, but it is actually pieced together almost like a jigsaw puzzle. So each section of this vacuum cleaner is actually a different piece of lace in a different color, a different type pattern of lace, that are jigsaw puzzled together using various color lurex, or metallic stitches on a sewing machine, an embroidery sewing machine. While the back of the dress is very simple-- although it does have a lot of work-- if you can see, the seams of the design were all pieced into these different rays. So we created the fit of the dress. I guess that's an important thing to point out. The fit of the behind of the dress is, rather than straight seams, it's all worked into the shaping that you can see within the seams or the cuts here. So rather than doing a straight seam to fit the behind, all of these seams that come around accommodate the behind. So the shaping is actually done through the design rather than through straight cuts or straight seams. The front of the dress is more of a t-shirt shape. So there is a cut here, if you can see, at the waist. And we avoided-- there's a small dart here in the bust, and a kind of invisible seam here. So we didn't draw any attention to the seam in the bust, or the dart here in the bust, or in the seam, because we didn't really want that to show. So we tried to keep this all about the design of the vacuum cleaner. And then we made the decorative cut which functions for shape only here in the waist. And then these other seams come around the back to fit the behind, which is obviously a fuller volume than what ...

Students give MasterClass an average rating of 4.7 out of 5 stars.

Interesting person! Learned more about fashion than most courses. Enjoyed the detail in examples.

As an amateur knitwear designer, I loved this Masterclass. I especially loved when he took specific designs and broke down the story of how they came to be. The cuts. The piecing. The materials. It's great to get into the mind of a successful person.

I’ve learned where to start , what I want to study , how’s to find inspiration and do the research. I’ve learned about fabrics and their role , and so on!

Marc was very open and honest about fashion. I enjoyed the stories he shared and I appreciated hearing and seeing his process to greatness.

So amazing great couture clothes !!! Thanks dear Mark for construction techniques explanation for each design! ! I love it!

cari B.

it would be so great to have the outfits/looks ALSO on model. so difficult to tell about movement and fit on a mannequin. the transference from one to the other would have been ideal...

Dear MasterClass, Hello. I liked learning about the two buttons that were placed on the sweater folds for one of the garments, in the "Case Study: Construction Techniques" lesson for the "Marc Jacobs Teaches Fashion Design" class. Thank you. Sincerely, Cristelle Nicole

I absolutely love the idea of taking something perfect, and making it imperfect. The beauty behind imperfection is capturing. IT resonates with the mind. It holds a powerful statement with life - which is an inspiration to say the least. Find perfection in imperfection.


The lace dress and sequinned jacket are exquisite. Not at all a fan of the sweater and skirt idea.

Do the models have to be skinny like the mannequins so the outfit fits on the model? @RJanesRealm

This was the final result of the construction project. My intention for this project was to creat a holiday inspired sweater using an old unused sweater that I didn’t really need anymore. The end product turned out to be very effective because this sweater definetely looks like one you could wear to a Holiday party.

This was the original sweater that I used for the project. The sweater was old and wasn’t being used anymore so I decided it would be perfect to use for this project.

Every chance I get to improve this lesson has allowed me to level up and create my expressions through trail and error and detail... it’s like coming close to becoming a surgeon

This has to be one of my most challenging experiences the breaking down and breaking up of the garment and creating some totally new thinking fall
