The Simple Woven Tank is the essential warm-weather staple and a fundamental learning project for woven garment sewing. Featuring a scooped neckline, all-in-one or traditional bias tape edge finishing, and a gently flared body that skims the waist and hips. Designed for woven fabrics with zero stretch, it incorporates comfortable positive ease at the bust and waist so you can move with complete freedom.
Front and back flats illustrating seam lines, hem curves, and design details.
Review both body benchmarks and finished garment ease before cutting your cloth.

Your physical body dimensions. Measure over undergarments with a snug tape.
Dimensions of the sewn garment, including designed wearing ease.
Select your size primarily based on your high bust measurement if you have a full bust cup (C cup and above), or your full bust measurement if you have an A/B cup. The tank provides 8–9 cm (3.1–3.5") of positive bust ease. If you measure between sizes, we recommend choosing the smaller size for a neater shoulder fit, or blending between bust and hip sizes following our guide.
Positive ease built into this pattern: +8 to +9 cm (+3.1" to +3.5") at bust, and +10 to +12 cm (+4" to +4.7") at hem sweep. Designed to float effortlessly over the torso without clinging or gaping.

Open the downloaded PDF in Adobe Acrobat Reader or a dedicated desktop PDF viewer. In the print dialog, select "Actual Size" or "Custom Scale: 100%". Never select "Fit to Printable Area". Always measure the calibration square on Page 1 before proceeding.
Before printing pattern tiles, print only Page 1 with scaling set to '100%' or 'Actual Size' in Adobe Acrobat or your PDF reader. Do not select 'Fit to Page'. Measure the printed 50 mm x 50 mm (Metric) or 2.0 in x 2.0 in [50.8 mm] (Imperial) test box with a reliable hard ruler. Proceed with printing only when measurements match exactly.

Butt trimmed edge against the adjacent page's marked registration lines. Match the diamond registration marks (1A, 1B, 2A, etc.) and secure with clear tape. Never overlap pages without trimming.
Draft construction notes. Readable online; review against the pattern pieces before sewing.
Staystitch the front and back neckline and armholes 10 mm (3/8") from the raw edge using a 2.0 mm stitch length. Stitch from the shoulder towards center front, and from shoulder towards the underarm. Staystitching prevents curved woven edges from stretching out of shape during handling.
With right sides together, pin Front Bodice to Back Bodice along the shoulder seams, matching neck edges and armhole notches. Stitch at 1.5 cm (5/8") seam allowance. Finish the raw seam allowances together with an overlocker/serger, zigzag stitch, or French seam. Press seam allowances toward the back.
Press your 3.5 cm bias strip in half lengthwise with wrong sides together. Pin the raw edges of the folded strip to the right side of the neckline, gently easing the strip around curves (bias tape should be approximately 10–12% shorter than the neckline perimeter). Stitch with a 6 mm (1/4") seam allowance. Grade seam allowance to 3 mm, understitch binding to allowance, then turn binding entirely to the garment inside and edgestitch in place.
In the same manner as the neckline, pin, stitch, understitch, and turn the armhole bias strips to the inside of both armholes. Press crisp and flat with ample steam.
With right sides together, align the front and back side seams, matching underarm seam junctions and hem notches. Pin securely. Stitch at 1.5 cm (5/8") from underarm down to the hem notch. Backstitch firmly at the hem slit reinforcement point. Finish allowances separately and press open.
Press up the lower hem edge by 6 mm (1/4") toward the wrong side. Fold up a second time by 9 mm (3/8"), encasing raw edges. Pin in place. From the inside, edgestitch the hem 1 mm from the inner folded edge. Give the entire garment a final thorough steam press.
Solutions for common fitting hurdles and construction errors specific to this garment.
Possible Cause: Bias binding was stretched during sewing or cut too long relative to the neckline opening.
Recommended Fix: Unpick the binding, gently steam-shrink the garment neckline with an iron, and shorten the bias strip by 2–3 cm so it stretches gently around the curve when pinned.
Possible Cause: High armscye or insufficient armhole depth for your shoulder slope.
Recommended Fix: Scoop out the underarm curve by 1 cm (3/8") tapering to zero at the mid-armhole notch before applying bias tape.
Possible Cause: Fabric was stretched or fed unevenly through standard presser foot.
Recommended Fix: Loosen presser foot pressure, use a walking foot if available, and use a generous burst of steam with a wooden clapper to set the fold.
