Making a bodice with built-in bra cups is a rewarding project that combines tailoring precision with intimate apparel construction. This guide will walk you through the entire process, from choosing the right materials to finishing the final garment, ensuring a professional, custom-fit result.
The Foundation: Choosing Your Materials and Tools
The success of your bodice begins with selecting the appropriate supplies. You’ll need more than just fabric; the right components will ensure comfort, support, and durability.
Fabric Selection
The outer fabric of your bodice sets the aesthetic tone, while the lining provides structure and comfort.
- Outer Fabric: Choose a woven, non-stretch fabric like cotton sateen, silk dupioni, brocade, or couture satin. These fabrics hold their shape well and are stable for intricate sewing. Avoid anything too slippery or stretchy, as it will be difficult to work with and won’t provide adequate support for the built-in cups.
-
Lining Fabric: A good lining is crucial. Use a tightly woven, breathable fabric like cotton batiste, silk habutai, or a high-quality rayon challis. The lining should be smooth against the skin and strong enough to support the garment’s structure.
-
Interfacing: This is the unseen hero of a structured bodice. A medium-weight fusible interfacing will add stability to your fashion fabric, preventing stretching and helping the bodice maintain its shape. Apply it to the bodice front and back pieces. For extra support, consider a non-woven sew-in interfacing like hymo or a cotton canvas.
Bra Cup and Support Materials
The built-in bra cups are the core of this project. Their quality and type are paramount.
- Bra Cups: You have a few options:
- Sew-in foam cups: These are widely available at fabric stores and come in various sizes. They’re a great starting point for beginners.
-
Underwire cups: These provide the most support and shaping, but require more advanced techniques for proper installation. They consist of a fabric cup and an underwire channel.
-
Deconstructed ready-to-wear bra: This is a cost-effective method. Purchase a well-fitting, inexpensive bra and carefully deconstruct it to salvage the cups and underwires.
-
Underwire: If using underwire cups, ensure you have the correct size. The underwire should sit comfortably at the base of the breast, following the natural curve without digging in.
-
Underwire Casing: This is the fabric tunnel the underwire slides into. It’s usually a plush, soft tape designed for comfort.
-
Bonafide Boning: Boning provides additional structure and shape. Choose steel spiral boning for curves and flat steel boning for straight seams. Plastic boning is less durable and can warp over time; it’s not recommended for a high-quality bodice.
-
Boning Casing: This is a fabric channel for the boning. It can be purchased pre-made or you can create your own with a strip of sturdy fabric like cotton twill.
Pattern and Sizing: Getting the Fit Right
A well-fitting bodice starts with an accurate pattern. You can either modify a commercial pattern or draft your own.
Modifying a Commercial Pattern
Choose a bodice pattern that has princess seams or multiple vertical seams. This makes it easier to install the bra cups and boning.
- Measure Yourself: Take precise measurements of your bust, underbust, waist, and torso length. Don’t skip this step.
-
Select Your Size: Use the pattern’s size chart, but be mindful that garment sizing can differ from ready-to-wear clothing.
-
Adjust the Pattern:
- Bust Adjustment: The most common adjustment is a Full Bust Adjustment (FBA) or Small Bust Adjustment (SBA). This ensures the bodice fits your bust without pulling or gaping.
-
Underbust Adjustment: Measure the pattern’s underbust line and compare it to your measurement. Adjust the seam lines to match your size.
-
Waist Adjustment: Taper the side seams to fit your waist measurement.
-
Length Adjustment: Lengthen or shorten the pattern pieces to match your torso length.
Draft Your Own Bodice Block
For a truly custom fit, draft a basic bodice block from your own measurements. There are numerous resources online and in sewing books that detail this process. A custom block is the foundation for all future fitted garments.
The Construction Process: A Step-by-Step Guide
This is where the magic happens. Follow these steps carefully for a professional result.
1. Preparing the Pattern and Fabric
- Cut the Pattern Pieces: Cut out your modified pattern pieces from the paper.
-
Cut the Fabric: Lay your fashion fabric on a flat surface. Pin the pattern pieces to the fabric, ensuring the grainline is straight. Cut out the pieces, adding a 5/8″ seam allowance if the pattern doesn’t include one. Repeat for the lining and interfacing.
-
Apply Interfacing: Following the manufacturer’s instructions, fuse the interfacing to the wrong side of your fashion fabric pieces. This provides a stable base for the intricate work to come.
2. Constructing the Bodice Shell
-
Sew the Seams: Pin and sew the vertical seams of the bodice front and back. For a clean finish, sew with a small stitch length (2.0-2.5 mm).
-
Press the Seams: Pressing is as important as sewing. Press the seams open neatly. Use a tailor’s ham to press curved seams.
-
Construct the Lining: Repeat the same process for the lining pieces.
3. Integrating the Bra Cups
This is the most critical part of the process.
- Mark the Placement: Try on your partially constructed bodice (the main shell) and mark the desired position for the bra cups with a fabric marker or pins. The cups should sit comfortably and provide the right amount of coverage.
-
Sewing in the Cups (Non-Underwire):
- Align the bottom edge of the foam cups with the underbust seam of the bodice lining.
-
Pin the cups in place, ensuring they are symmetrical.
-
Using a hand-sewing needle and a strong thread, stitch the cups to the lining around their perimeter. Use a small whipstitch or a running stitch. Be careful not to stitch through to the outer fabric.
-
Sewing in the Cups (Underwire):
- Deconstructing a Bra: If you’re deconstructing a bra, carefully cut the cups away from the bra band and straps. Leave a small seam allowance around the cups.
-
Attaching the Casing: Pin and sew the underwire casing to the underbust seam of the bodice lining. Ensure the plush side of the casing is against the lining, and the seam allowance is tucked away. Sew along both edges of the casing.
-
Inserting the Underwire: Once the casing is sewn, carefully slide the underwire into the channel. Secure the ends of the channel with a few hand stitches to prevent the underwire from slipping out.
-
Attaching the Cups: Position the cups over the underwire casing and pin them to the lining. Hand-stitch the cups to the lining using a small, invisible stitch.
Boning and Structure: Providing Shape and Support
Boning is what gives a bodice its classic structure and prevents it from collapsing or wrinkling.
1. Determining Boning Placement
- Princess Seams: The seams where the front and side pieces meet are ideal for boning.
-
Back Seams: The seams on the back, especially the center back seam, are crucial for providing support and a smooth line.
-
Side Seams: Boning the side seams helps to maintain the shape of the waist and torso.
2. Installing Boning Casing
-
Cut the Casing: Measure the length of each seam where you plan to install boning. Cut the boning casing to that length.
-
Sew the Casing: Pin the casing to the wrong side of the bodice lining, centered over the seam. Sew along both long edges of the casing.
3. Cutting and Inserting Boning
-
Measure the Boning: Measure the length of the casing. Cut the boning about 1/2″ shorter than the casing to allow for seam allowances at the top and bottom.
-
Insert the Boning: Slide the boning into the casing.
-
Secure the Ends: Hand-sew across the top and bottom of the casing, just above and below the boning, to secure it in place.
Finishing Touches: The Professional Final Steps
The finishing touches are what elevate a homemade garment to a professional-looking piece.
1. Joining the Shell and Lining
- Sew the Top Edge: With right sides together, pin the bodice shell and the lining at the top edge. Sew along this seam.
-
Grade and Clip: Grade the seam allowance by trimming it to different lengths (the fashion fabric’s allowance slightly longer than the lining’s). Clip curved seams to allow them to lie flat.
-
Turn and Press: Turn the bodice right side out. Press the top edge neatly, rolling the seam line slightly to the inside so it’s not visible.
2. Attaching the Bottom and Closure
-
Sew the Bottom Edge: If you’re attaching a skirt, this is the time to do it. Pin the bodice to the skirt, right sides together, and sew.
-
Hem the Bottom (if not attaching a skirt): Turn the bottom edge of the bodice under and press. Hand-sew a blind hem or use a sewing machine for a clean finish.
-
Closure Options:
- Invisible Zipper: A classic choice for a sleek, clean look.
-
Lacing/Corset Back: Creates a beautiful, adjustable fit. Install grommets or eyelets along the center back seams. Use boning on either side of the grommets to prevent the fabric from bunching.
-
Hook and Eye Closure: A simple and effective closure, particularly for shorter bodices.
Troubleshooting Common Issues
Even experienced sewers encounter problems. Here are solutions to some common issues.
- Gapping at the Bust: This usually means the bust cups are too small or the bodice pattern needs a Full Bust Adjustment (FBA).
-
Wrinkling or Bunching: The boning may be too long or the bodice is too loose. Ensure the boning is slightly shorter than the casing and that the bodice is snug but comfortable.
-
Cups Shifting: The cups are not securely sewn to the lining. Reinforce the stitches, especially around the perimeter of the cup.
-
Lining Peeking Out: The top seam was not pressed correctly. Turn the bodice inside out, press the seam open again, then turn right side out and press again, rolling the seam slightly to the inside.
A bodice with built-in bra cups is a sophisticated garment that requires careful planning and execution. By following this detailed guide, you can create a piece that is not only beautiful but also provides the support and comfort of a professionally tailored garment. The combination of structural boning and well-integrated cups will result in a stunning and perfectly fitting bodice you’ll be proud to wear.
