Guidance on choosing a size and modifying fit:
Use your desired length as a guide for choosing a size.
For example, if you usually make a size S to fit your bust measurement but want a longer top, start with the instructions for the size that corresponds with your desired length.
Then in the Main Rectangle instructions, see how many rows the size S needs, and stop there.
By doing this you will get the longer length but the top will still fit you appropriately at the bust.
For a shorter top, choose a smaller size to start with, then continue working rows until you reach the row count for your usual bust size.

!! Gauge Check !!
Please don’t skip this step or you will risk your tee not fitting as expected. Part 1 of the video tutorial above walks you through each step of this.
To check gauge:
Foundation Row: Ch 38.
Row 1 (RS): Dc in 4th ch from hook (3 sk ch count as dc), dc in next 3 ch, *ch 1, sk next ch, dc in next 4 ch, rep from * across, dc in last ch; turn. (7 clusters + 2 dc)
Row 2 (RS): Row 2 (WS): Ch 1, sc in first dc, *ch 4, sc in next ch1sp, rep from * across, placing last sc in tch; turn.
Row 3 (RS): Ch 3, 4 dc in next ch4sp*, ch 1, rep from * across, ending last repeat at **, dc in sc; turn.
Repeat Rows 2 and 3 until you have 16 rows.
How To Measure and Adjust Hook Size
Measure center four inches of swatch vertically and horizontally (5 clusters and 12 rows). Compare to pattern gauge listed above.
- If there are too many stitches in 4” horizontally, increase your hook size and re-swatch.
- If there aren’t enough stitches in 4” horizontally, decrease your hook size and re-swatch.
- If swatch is measuring too small vertically, make a deliberate effort to pull loops up a bit higher before completing each double crochet.
- If swatch is measuring too large vertically, make an effort to work the loops of each double crochet a little tighter.
- This video is incredibly helpful if you’re having trouble achieving the correct vertical gauge:

Main Rectangle
Notes:
- Work Row 1 slightly tighter than usual so it will match subsequent rows. If it helps you achieve a tighter tension, use a hook size down for this row only. Then, return to the hook size your gauge swatch is based on for Row 2 and beyond.
- Chain 3 at beginning of row counts as one double crochet.
Make 2.
Leaving a 36” tail for seaming later, tie a slip knot on your hook.
Foundation: Ch 238 (243, 253, 258, 263)(268, 273, 278, 283).
Tip: Place a stitch marker every 50 chains to make counting easier.
Row 1 (RS): Dc in 4th ch from hook, dc in next 3 ch, *ch 1, sk next ch, dc in next 4 ch, rep from * across, dc in last ch; turn. (47 (48, 50, 51, 52)(53, 54, 55, 56 clusters + 2 dc)
Row 2 (WS): Ch 1, sc in first dc, *ch 4, sc in next ch1sp, rep from * across, placing last sc in tch; turn.
Row 3 (RS): Ch 3, * 4 dc in next ch4sp**, ch 1, rep from * across, ending last repeat at **, dc in sc; turn.
🧶 Pause to measure the width of your piece. It should be approximately 39.5 (40, 42, 42.5, 43.5)(44.5, 45, 46, 47)” wide. It might shrink a bit more as you proceed. If you’re off by more than 5-6”, the length of your top won’t be as expected and it’s better to start over with more or fewer chains. (See notes in Sizing section on getting the
length you desire.)
To continue: Repeat Rows 2 and 3 eleven (thirteen, fifteen, sixteen,
eighteen)(nineteen, twenty, twenty one, twenty three) more times. Repeat Row 2 once more.
You should now have a total of 26 (30, 34, 36, 40)(42, 44, 46, 50) rows. Your rectangle should be approximately 9 (10, 11.5, 12, 13.5)(14, 15, 15.5, 17)” tall. Don’t fasten off quite yet.
⚠ If the rectangle height is shorter than expected, work additional repeats of Rows 2-3, ending with a Row 2.
⚠ If the rectangle height is taller than expected, proceed to the next section and evaluate the fit before tearing out rows.
Blocking and Fit Check
Blocking: Once your two rectangles are complete, it’s helpful to steam block them to smooth out any differences in tension and make sure both are measuring the same size. Learn more about blocking here.
Evaluate the Fit: Now it’s time to pin the rectangles together and evaluate the fit. Check out the diagrams at the end of the pattern for visual guidance.
1. Lay both rectangles with the right side facing up. Position the final rows so they’re touching.
2. Using stitch markers, pin the final rows together working from the edge of the rectangles inward. Leave roughly an 18-20” opening unpinned for the neckline.
3. Fold the rectangles in half and pin the foundation chain to itself on both sides of the tee, leaving an opening for your arms. (The exact size of the armhole doesn’t matter at this point.)
4. Try your tee on and double-check the fit. First, consider which side you’d like to be the front and which will be the back. I like to pin a name tag to each to stay oriented.
Evaluate where you’d like the neckline to fall in the front and back and adjust the placement of the stitch markers. (Each marker should be in a single crochet.) Make sure the opening is large enough to fit your head through.
🧶 If the tee is fitting tighter or looser than desired, this is the time to add or remove rows from your rectangles. Be sure to end with a Row 2.
5. Leave the marker indicating the front neckline on the right rectangle (as worn) in the appropriate single crochet stitch. Leave the marker indicating the back neckline on the left rectangle (as worn) in the appropriate single crochet stitch. Remove all other markers.
Our Latest Crochet Inspiration:
Here are a few more free crochet patterns and tutorials that are hot off the presses.
Rectangle Edging
We will now add an edging to each rectangle working along a portion of the last row. In the front of the tee, this will form our faux button hold flap. In the back, we’ll seam this edging to join the rectangles.
Faux Button Flap (FRONT)
This is added to the right rectangle (as worn).
Right-handed: Use attached yarn.
Left-handed: Fasten off attached yarn and reattach in marked stitch.
Row 1 (RS): Ch 1, *sk next sc, 4 sc in next ch4sp; repeat from * across to first marker at front of neckline, sc in marked st; turn. (Stitch count varies based on preference.)
Row 2 (WS): Ch 1, sc in each sc from previous row; turn.
Row 3 (RS): Repeat Row 3.
Fasten off, leaving a 36” tail for seaming.
Edging (BACK)
This is added to the left rectangle (as worn).
Right-handed: Use attached yarn.
Left-handed: Fasten off attached yarn and reattach in marked stitch.
Follow Rows 1-3 of Front. The stitch count might vary from the front depending on the placement of your markers.
Fasten off, leaving a 36” tail for seaming.
Seaming Back
With RS of fabric facing up, position rectangles next to each other with the button flap and back edging facing each other.
Use stitch markers to pin Right rectangle to Back Edging. It’s important to line up the clusters on both the R and L rectangles so that the visual “grid” of the stitches looks intentional.
Using one of the leftover yarn tails and a tapestry needle, seam the back edging to the Right Rectangle using the zig zag mattress stitch.
Seaming Front
With RS of fabric facing up, position rectangles next to each other with the button flap overlapping the corresponding edge of the Left rectangle.
This means the button flap essentially covers the first row of clusters on the opposite rectangle. (See diagram at end of pattern PDF for more guidance.) Again, check that the clusters are lined up visually.
Using one of the leftover yarn tails and a tapestry needle, seam the button flap to the Left Rectangle using a basting stitch. For better durability in the washing machine, use a stitch to tack down the short sizes of the button flap at the top and bottom of the seam.

Joining Sides of Tee
Preparation:
We are going to work a setup row along the foundation chain of each rectangle to get them ready for seaming.
Right-handed: With RS of fabric facing, attach yarn at right corner of the foundation chain on one of the rectangles.
Left-handed: With RS of fabric facing, attach yarn at left corner of the foundation chain on one of the rectangles.
Set-Up Row (RS): Ch 1, sc in the bottom loops of each ch across. An exact stitch count doesn’t matter here. What’s more important is that your row lays flat and your tension is even.
Fasten off leaving a 36” tail for seaming.
Repeat on second rectangle.
Pinning Armholes:
RS facing out, use stitch markers to pin the set-up row to itself, leaving an opening for the armhole. Try on your tee to determine your desired opening size. I suggest between 7-11” depending on size and personal preference.
Seaming Sides:
Using the leftover yarn tail and a tapestry needle, seam the sides using the zig zag mattress stitch.
Repeat on opposite side of tee.
Sleeve Edging
Now, we’ll add a reverse single crochet (crab stitch) border around each sleeve. While this stitch can feel weird at first, you are indeed supposed to work in the opposite direction as you typically do with single crochet. It’s okay that the stitches will twist, this is intentional.
Right-Handed: With the RS facing, this edging will be worked counterclockwise.
Left-Handed: With the RS facing, this edging will be worked clockwise.
Attach yarn in armhole seam.
Round 1 (RS): Ch 1, rsc in each sc around armhole, join with slst to first rsc. Fasten off and weave in ends.
Repeat with second sleeve.
Finishing
Additional Blocking: Do a quick steam blocking of any seams that aren’t laying as smoothly as you’d like.
Weaving in Ends: Tackle this with your favorite podcast playing – you shouldn’t have too many! Learn more about what to do with yarn tails here.
Attaching Buttons: The number of buttons you’ll need depends on the length of your button flap. I suggest one button per 1.75-2”.
With a sewing needle and thread that matches your yarn, sew each button to the flap.
Toss on your tee, grab a lemonade and pay a visit to the nearest tidepool!
