Ribbing is one of those stitch choices that does a lot of structural work without adding any complexity to the pattern the vertical columns pull the fabric in, give the tube top its stretch, and mean you don’t need elastic or a drawstring to keep everything in place. Bright yellow makes the ribs pop more than a neutral would, and the result reads as bold even though the construction is about as straightforward as crochet garments get. If you like this fitted strapless silhouette and want to see it in a different stitch texture, the crochet tube top with mesh covers the same basic shape with openwork rows instead.
Crochet Tube Top
The top works as a flat ribbed panel that you seam into a tube at the end so you can measure and adjust the width before committing to the join, which takes a lot of the guesswork out of sizing. Front and back post stitches alternate to build the ribs, and once you have the rhythm it’s essentially a single repeating row all the way up. For a ribbed-waistband detail in a shorts pattern from the same creator, the crochet shorts for kids uses the same source and shows how the ribbing technique translates across garment types.

Stitch That Make Up This Pattern
Foundation
- Make a slip knot and chain 41
- Keep chains slightly loose and prepare to work into the back bumps
Why this matters: A tube top depends on horizontal stretch, not height stretch. By chaining loosely and working into the back bumps, you create a foundation edge that behaves like a row of stitches instead of a stiff chain. This makes the lower edge more flexible and helps prevent digging or rolling when worn.
Tip for tension: If your chains are naturally tight, go up half a hook size just for the chain, then switch back to the 5.0 mm hook before Row One.

Row One Ribbing Setup
- Turn the chain to locate the back bumps
- Skip the first chain and single crochet into the next 5 back bumps
- Half double crochet into each back bump across the center section
- Single crochet into the final 5 back bumps
What’s happening here: This row establishes three zones:
- Single crochet edges on both sides for firmness and shape
- Half double crochet center for stretch and comfort
Those solid side columns help the tube keep its shape vertically, while the center section stretches horizontally to hug the body.
Common confusion: If the back bumps feel hard to see, gently roll the chain toward you. The bumps form a neat ridge along the underside of the chain.
Body Rows
- Chain 1 and turn
- Work all stitches in the back loop only
- Single crochet in the first 5 stitches
- Half double crochet across the center stitches
- Single crochet in the last 5 stitches
- Repeat this row until the panel reaches your desired width
For reference, 80 rows create approximately a 13 inch wide by 8 inch tall top
- Why back loop only is used: Working into the back loop creates vertical ridges that act like knit ribbing. This gives the fabric stretch without becoming floppy and helps the tube top stay in place during wear.
- Measuring correctly: The “width” here becomes the circumference of the tube once seamed. Measure the panel while it is relaxed, not stretched. It should sit slightly snug against the body, as cotton blends tend to relax a little with wear.
Assembly and Finishing
- Fold the piece in half with the wrong side facing out
- Align the short edges and join using slip stitches through both layers
- Chain 1 and fasten off at the end of the seam
- Weave in all yarn tails securely
- Turn the tube top right side out to complete the project
Why slip stitch seaming works here: Slip stitches create a flat, flexible seam that doesn’t interrupt the stretch of the ribbing. When turned right side out, the seam blends into the texture instead of forming a bulky ridge.
Fit and Sizing Guidance
- For a secure fit, aim for the finished tube to be 1–2 inches smaller than your actual bust measurement.
- If you prefer a relaxed lounge fit, match your measurement exactly.
- The height can be adjusted easily by adding or removing rows after the first fitting check.
Try the panel around your body before seaming if possible. This is the best moment to fine-tune comfort.
Stitch and Shaping Clarity
- Single crochet edges act as built-in structure. Do not replace them with half double crochet or the top may collapse at the sides.
- The center stretch comes from the stitch choice and loop placement, not from adding extra chains or spacing.
- Consistent turning direction keeps the ribbing even and prevents twisting texture.
Beginner Notes
- Use stitch markers to mark the first and last five stitches until the rhythm feels natural.
- If your edges look wavy, your chains were likely too loose. If they feel tight, loosen your turning tension slightly.
- This pattern is simple in shape but relies on consistency—slow, even rows produce the best result.
Troubleshooting
- Top slides down: The panel is likely too wide. Remove a few rows and reseam.
- Fabric feels stiff: Switch to a hook one size larger or relax your tension in the half double crochet section.
- Ribbing looks uneven: Check that every stitch is worked strictly into the back loop during body rows.
