How to create a custom dress form using duct tape and a T-shirt

A custom dress form gives you a reliable reference for draping and pattern testing. Unlike a shop-bought dummy, it can follow your posture, shoulder width, bust shape and waist position. It also captures small differences between the left and right sides, details that often matter when you are altering a commercial pattern. The form becomes most useful once it is covered in fabric and placed at the height you actually sew at.

The basic method combines a close-fitting T-shirt with cloth-backed duct tape. The shirt supplies a stable first layer and reveals the shape you want to preserve, while the tape creates a firm torso that can later be covered with jersey or another fabric. Work in short sessions rather than trying to wrap the whole body at once: the waist and underbust establish control, the bust and shoulders define volume, and the hips create balance.

Plan the project as both a fitting exercise and a lasting piece of equipment. In Australian sewing rooms, the same object may be called a dress form, a stand or a dressmaker’s dummy, so search for tutorials using those terms as well. The finished form should reproduce the body you are designing for rather than an idealised shape, with enough room for the garments and layers you normally wear.

Plan the form around your body

Gather a clean, close-fitting T-shirt, 50–75 mm cloth-backed duct tape, sharp fabric scissors, a flexible tape measure, a washable marker or tailor’s chalk, pins, paper, and a dowel or ready-made dress-form stand. Bunnings and Mitre 10 are convenient places to compare tape widths, or you can order a roll online. Choose tape that bends without splitting and has enough adhesive to hold a curve. Use metric measurements throughout, as Australian pattern books generally do.

Measure and mark the bust at its fullest point, underbust, natural waist, high hip, full hip, shoulder width and front-to-back depth. Add the distance from your waist to the point where you want the form to end, usually the upper thigh. Stand normally while taking these measurements, with your shoulders relaxed and your weight balanced. If you design mostly for workwear or layered clothing, measure over the type of garments you expect to make.

Select a T-shirt after taking your measurements. Wash it first so the fabric has relaxed, then choose one without lumps, heavy quilting or a loose neckline. It needs to follow the body closely without pinching. Australian sewists often find useful remnants at a Vinnie’s or Lifeline op shop, where a fitted tee, jersey lining or stretch fabric can cost very little.

Cut and shape the T-shirt

Put on the T-shirt with the usual bra or foundation garment you plan to use for fitting. Lightly mark the centre front, centre back, underbust, waist and high-hip lines with removable tape or chalk. The centre lines will help you keep the form symmetrical, while the horizontal lines give you consistent references when adding tape. Check each mark from the side and the back before moving on.

Cut the sleeves away close to the armholes and remove any loose threads or bulky labels. Leave the main body of the shirt intact because it supports the tape and helps prevent the initial shape from collapsing. If the shirt is slightly loose at the waist, take small darts from the side seams and smooth the excess flat against the body. Do not pull the fabric tightly; the finished form should reflect a comfortable standing shape.

Use the marked T-shirt to check how much material you have at the bust, waist and seat. The fabric should cover the area without creating deep folds. At the waist, distribute any fullness evenly instead of gathering it into one large dart. At the bust, retain the volume supported by the bra rather than flattening it against the ribs. These small shaping decisions determine whether the completed form will fit a garment accurately.

Build the torso with duct tape

Begin at the underbust and natural waist, where the body provides a stable starting point. Apply strips of tape around the torso in horizontal rows, overlapping each strip by roughly one-third to one-half of its width. Work upward toward the shoulders and then downward toward the hips. Keep the strips level, but allow them to curve naturally around the ribcage. Pull gently as you smooth them into place.

Change direction around the bust. Long vertical strips rising from the underbust can preserve the curve of each cup, while shorter curved pieces define the upper edge. Smooth the tape toward the centre front without compressing the bust. Continue over the shoulders, using the T-shirt seams as guides for their position. A helper is useful for reaching the centre back and checking that both shoulders sit at the same height.

Close and reinforce the torso once the surface is secure. Add short pieces of tape across the centre front, centre back, side seams and underbust to prevent the strips from separating. Cut carefully along the edges of the T-shirt beneath the tape, leaving a narrow fabric margin if you want to use the shirt as a soft inner layer. Keep your scissors away from the reinforced joins, and work in sections if the adhesive starts to pull at the fabric.

Add the hips and a stand

Continue from the waist toward the upper thigh with overlapping horizontal strips. Shape the seat with a few vertical pieces of tape that curve inward toward the centre back, then reinforce the side seams and centre front. Keep the lower edge level and firm enough to support the form, but do not tape the legs together. A simple torso form is more versatile than a full figure and is sufficient for most dress and blouse patterns.

Decide whether you want a hollow or lightly filled shell. A hollow form is lighter, cleaner to cover and easier to store, although it needs a rigid stand. If small gaps appear, reinforce them with short tape tabs rather than packing the entire shape tightly. Stuffing with loosely crumpled paper can preserve an area, but it may distort the measurements later. Leave the waist and bust unmarked so the covering fabric remains smooth.

Attach the shell to a stand once it is firm. A timber dowel can be inserted through a reinforced slot in a plywood or cardboard base, with tape used to secure the connection. Alternatively, clamp the form to a commercial dress-form stand if you already own one.

Cover and check the fit

Choose a fabric with enough stretch to follow the bust, waist and seat without pulling the tape shell out of shape. Four-way stretch jersey, Lycra blend or a well-fitting spare T-shirt will work for a removable cover. Woven cotton is less forgiving, but it can create a crisp outer layer if you ease it carefully. Allow for the extra thickness of seams by fitting the cover over the finished form rather than cutting it from flat measurements.

Drape the fabric over the form and pin it at the centre front, centre back, sides and shoulders. Fit darts or shaped seams over the bust and waist, then join the panels with a stretch stitch, overlocker or narrow zigzag seam. Leave an opening at the bottom if you want to remove the cover for washing or repairs. The finished surface should be smooth enough for pins to remain in place while you drape a muslin toile.

Check the covered form against your original measurements and compare it with the body it represents. Dress it in a simple bodice or blouse and look for differences around the bust, armhole, shoulder and waist. Australian online sewing suppliers normally show consumer prices in Australian dollars, including GST, although shipping can change the final cost. Melbourne makers often combine fabric from local op shops with remnants ordered from Australian shops, making it easier to test several cover options before committing.

Make the form ready for daily use

Label the base with the date and your main measurements. Keep a paper record of the bust, waist, hip, shoulder and height measurements, as these will help if the cover needs replacing later. Store the form in a cool, dry room away from direct sunlight, then cover it with a clean cotton sheet or purpose-made dust cover. In humid weather, remove the outer cover occasionally so trapped moisture cannot reach the tape.

Use the form for fitting bodices, checking pleats, comparing sleeve placement and drafting alterations before cutting a full garment. Keep sharp pins in a separate container rather than leaving them in the cover, and inspect high-pressure areas regularly for loose tape or frayed fabric. Small repairs are much easier to handle while the problem is still minor.
