Setup Instructions
Carefully unpack all components and ensure all parts are present before beginning assembly. Refer to the diagrams for visual guidance.
1. Assemble the Tripod Stand:
Attach the three legs to the central base of the tripod stand. Ensure they are securely fastened. Insert the main support pole into the assembled base. Tighten any locking mechanisms to secure the pole at its lowest position initially.

2. Attach the Dressform Body:
Carefully place the dressform body onto the top of the main support pole. The dressform has two openings at the bottom: a central opening for standard garment fitting and an off-set opening for pant fitting. Choose the appropriate opening and slide the dressform onto the pole. Secure the dressform body to the pole using the provided screws or locking mechanism. Ensure the dressform is stable and does not wobble.
Note: It may be helpful to have a second person assist in holding the dressform steady while securing it to the stand.
Operating Instructions
The Dritz My Double Deluxe Dressform features 12 adjustment wheels and an adjustable height to customize it to specific measurements. Always make adjustments incrementally and evenly.
1. Adjusting Body Measurements (Bust, Waist, Hips):
The dressform has adjustment wheels located at the bust, waist, and hip sections. There are four wheels for each section (two at the front, two at the back). To adjust a measurement:
- Locate the adjustment wheels for the desired section (e.g., bust).
- Turn each wheel slowly and evenly to expand or contract the dressform. Adjust all four wheels for a section in small increments to avoid binding or damage.
- Use a tape measure to verify the circumference until the desired measurement is achieved.

2. Adjusting Neck and Back Waist Length:
The neck circumference can be adjusted using a dedicated wheel. The back waist length is adjusted by loosening internal screws and sliding the upper torso section up or down. Ensure these screws are tightened securely after adjustment.

3. Adjusting Height and Hem Marker:
The overall height of the dressform can be adjusted by loosening the locking mechanism on the main support pole and sliding the dressform up or down. Re-tighten the mechanism firmly once the desired height is reached. The included hem marker can be attached to the pole to assist in marking garment hems accurately.
4. Pant Fitting Feature:
For fitting pants, utilize the off-set pole position. This allows pants to hang naturally, providing a more accurate fit. To switch to pant fitting, remove the dressform from the central pole, and re-attach it using the off-set opening at the bottom of the dressform body.
Maintenance
- Cleaning: Wipe the dressform's nylon cover with a damp cloth as needed. Avoid harsh chemicals that may damage the fabric or foam.
- Pinning: When pinning fabric to the dressform, insert pins parallel to the surface to prevent damage to the foam backing and ensure secure placement.
- Storage: Store the dressform in a dry, temperate environment. If disassembling for storage, ensure all parts are kept together.
- Lubrication: Periodically check adjustment mechanisms. If they become stiff, a small amount of silicone spray lubricant can be applied to the internal moving parts, avoiding contact with the fabric cover.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Adjustment wheels are stiff or difficult to turn. | Uneven adjustment; mechanisms may be dry. | Ensure all wheels for a section are adjusted incrementally and evenly. Apply a small amount of silicone spray lubricant to internal mechanisms if needed. |
| Dressform wobbles on the stand. | Stand components not fully tightened; dressform not securely attached. | Verify all tripod legs are securely fastened. Ensure the dressform body is firmly attached to the support pole and all locking screws are tightened. |
| Pins do not hold securely. | Pins inserted incorrectly; foam backing worn. | Always insert pins parallel to the dressform surface. If the foam is worn, consider using a padded cover. |
| Difficulty adjusting back waist length. | Internal screws not sufficiently loosened. | Ensure the internal screws that control the back waist length are fully loosened before attempting to slide the torso section. Re-tighten firmly after adjustment. |
