I would not have had the confidence to try bra-making without instruction. Now I feel I've seen enough of the basics to experiment and learn more on my own.

Class Description

Anyone can sew their own clothes! It just takes a little imagination, some instruction, and practice.

In our Bra-making Sewing Intensive, learn professional sewing techniques to sew your own underwire bra. In this class students cut, sew, fit, and alter the Harriet bra designed by Cloth Habit in sizes 28A to 42H (UK cup sizes). We help students develop skills to empower their decision-making in future bra-making projects at home.

As part of our Learn to Sew classes, sewing instruction is taught with an emphasis on key industry skills and techniques to create garments that look well-made. All of our sewing classes are both fun and productive, instead of just one or the other. We encourage anyone who is interested in sewing clothes to join us for our sewing classes, whether you are strictly a hobbyist or interested in learning clothing construction skills to bring your original fashion designs to life.

Our Bra-making Sewing Intensive is like taking a 2-day sewing vacation, and we’ve taught wonderful students who have visited us from all over the world. We invite you to spend two days working with us in our inspiring and friendly studio. After this class you’ll start your week with lots of excitement to continue your sewing adventures at home!

Classwork includes…

  • How to choose the best fabrics and notions for bra-making.
  • How to prep, cut, and mark bra-making and lingerie fabrics.
  • How to sew sheer fabrics, stretchy knit fabrics, lace, and other specialty fabrics for bra-making.
  • Specialty stitches, seams, and edge finishes for sewing lingerie.
  • How to work with and apply elastics.
  • How to sew hardware for bras.
  • How to sew bra straps.
  • The basics of bra fitting and pattern alterations to improve the fit of your bra. While we do cover the basics of fitting, this is a construction-focused—not fit-focused—class.

Tuition includes…

  • Lunch and treats both days.
  • Cloth Habit’s Harriet underwire bra sewing pattern.
  • Handouts and other supporting materials.
  • Use of studio equipment and tools.

If you prefer to work on your own sewing machine, you are welcome to bring it.

Due to the unique nature of this course, students are required to purchase a supply kit for this class from Workroom Social for this class. Each kit includes all the supplies needed for this class. No additional supply purchases are required of students.

  • Experience using sewing patterns to create clothing.
  • Experience with or desire to learn how to sew sheer fabrics and stretchy knit fabrics.

This class is designed for a confident beginner level sewist and above.

Hear from Past Students

The space was fantastically set up, the content was excellent, the resources provided were well thought out and relevant (and things I will use in my own sewing from now on), and the company was wonderful!

When you leave Workroom Social you feel skilled and empowered. The explanation, the attention, the space—it was truly one of the best experiences I have had.

Our Expertise and Approach

At Workroom Social, we teach adults how to sew clothes that fit their individual styles and unique body shapes and sizes.

We create a supportive and non-competitive environment in all of our classes. Perfection is never our goal in the classroom. Students should expect that their skills will improve with practice over time.

Our team of professional designers and sewists make garment sewing approachable, and it’s our goal to provide students with the confidence and knowledge they need to continue practicing sewing at home.

Our Belief in the Power of Sewing

Through sewing we build communities, stimulate creativity, and help improve women’s self-esteem and confidence by empowering them to sew the clothes they want to wear.

We work hard every day to promote a sense of accomplishment in our students and customers by reminding them of their abilities. Together we learn from each #sewingfail and celebrate every #sewingwin, no matter how small.

We use our shared passion for sewing to connect with those we might not meet otherwise, and we create opportunities for our students to develop relationships that go far beyond sewing itself.

About the Instructor

She then completed the Fashion Design program at Parsons School of Design, and has interned at various designer and luxury brands. Katy now works as a patternmaker in New York RTW for both men and women. You can see her most recent work on Instagram.
