How to Make a Tube Top from a Tee

Materials You’ll Need

• One clean, stretchable cotton T-shirt (any color or print)
• Ruler or measuring tape
• Fabric chalk or washable marker
• Sharp fabric scissors
• Elastic band (optional, for extra support)
• Sewing machine or needle and thread (or fabric glue for a no-sew version)
• Pins or clips

Step 1: Select and Prep Your T-Shirt

1. Choose the right fabric: A T-shirt with at least 5% spandex or elastane holds shape better as a tube top.
2. Wash and dry: Make sure your shirt is clean to avoid shrinkage after the project.
3. Lay it flat: Smooth out wrinkles on a flat surface—this ensures your cutting lines stay straight.

Step 2: Measure and Mark Your Tube Top

1. Determine the desired length: Try on the shirt and use chalk to mark where you want the top edge of the tube top to sit (just above the bust line).
2. Add seam allowance: From that mark, measure an additional 1–1.5 inches downward to create a seam allowance or hem fold.
3. Draw a straight line: Use a ruler and fabric marker to connect your marks all the way around each side of the shirt.

Step 3: Cut the T-Shirt

1. Cut off the top: Carefully cut along the marked line to remove the upper portion of the shirt. You can keep the remaining fabric for other DIY projects!
2. Trim excess: If the hem allowance is larger than 1.5 inches, trim it down for a neater finish.
3. Smooth the edge: Lightly stretch the cut edge to help prevent fraying—this technique encourages the fabric to curl slightly for a polished look.

Step 4: Create a Hem for Support

Option A: Sewing Machine or Hand-Stitching

1. Fold the edge: Fold the top raw edge inward along your seam-allowance line.
2. Pin or clip: Secure the fold evenly around the entire top.
3. Stitch: Sew a straight stitch around the tube’s circumference, catching both layers. Backstitch at the start and end to secure.

Option B: No-Sew Method

1. Fabric glue: Apply a thin bead of fabric glue along the inside fold.
2. Press and hold: Fold the hem inward and hold or clip for the glue’s recommended drying time.

Step 5: Add Elastic (Optional but Recommended)

For extra grip—especially useful if your shirt has less stretch—incorporate a length of narrow elastic.

1. Measure elastic: Wrap the elastic around your bust where the top will sit, subtracting about 1 inch for a snug fit.
2. Form a loop: Sew the elastic ends together to create a loop.
3. Attach inside hem: As you sew or glue the top hem, sandwich the elastic between the layers; stretch it slightly as you go so it gathers evenly.

Step 6: Final Touches and Customization

• Edge embellishment: Add lace trim or ribbon along the bottom hem for a feminine flair.
• Gathered style: Sew vertical lines of elastic thread on the sides to create gentle ruching.
• Strap hack: Use scrap fabric or leftover T-shirt strips to fashion removable straps—loop them through the hem and knot.

Styling Your DIY Tube Top

• Casual summer vibe: Pair with high-waisted denim shorts, chunky sandals, and layered necklaces.
• Evening glow: Tuck into a flowy maxi skirt, add strappy heels, and a bold statement belt.
• Layered look: Wear under an open linen button-down or oversized denim jacket for transitional weather.
• Festival ready: Add body glitter, fringe vest, and ankle boots for an eclectic, boho ensemble.

Troubleshooting Common Issues

• Tube top slipping down: Ensure your elastic measurement is snug and that it’s properly sandwiched in the hem.
• Uneven hem: Press and pin carefully, and use a walking foot on your sewing machine to feed layers evenly.
• Fabric fraying: Opt for a no-fray knit T-shirt or use a zigzag stitch along the raw edge before folding.

Conclusion

Creating your own DIY tube top from a T-shirt is a quick, eco-friendly project that rewards you with a one-of-a-kind summer staple. Armed with just a few tools and a willingness to experiment, you can customize length, fit, and embellishments to match your personal style.
