Special Stitch Instructions

• Single Crochet (sc): Insert hook into the stitch, yarn over, pull up a loop, yarn over, and pull through both loops.
• Half Double Crochet (hdc): Yarn over, insert hook, pull up a loop, yarn over, and pull through all three loops.
• Double Crochet (dc): Yarn over, insert hook, pull up a loop, yarn over and pull through two loops twice.
• Treble Crochet (tr): Yarn over twice, insert hook, pull up a loop, then work through two loops three times.
• Shell Stitch: Work 5 dc into the same stitch or space.
• V-Stitch: Work (dc, ch 1, dc) into the same stitch or space.
• Picot: Ch 3, sl st into the first chain.
• Mesh Space: Ch 1, skip 1 stitch, then work the next stitch as instructed.
• Butterfly Shell: Work 5 dc into the designated stitch, followed by a ch-3 picot at the center of the shell.

Important: Turning chains do not count as stitches unless a step explicitly says they do.

Gauge

Gauge is important because this top needs to fit comfortably while maintaining its delicate lace appearance.

• 18 dc = 10 cm (4 inches).
• 10 rows of dc = 10 cm (4 inches).

Using the 3.5 mm hook, chain 21 and work dc across the chain. Chain 2 and turn. Continue working dc rows until the swatch measures approximately 10 cm. Measure the center portion. If your swatch is too wide, try a smaller hook. If it is too narrow, move up one hook size.

For the lace sections, focus on keeping your chain spaces consistent rather than making them excessively tight.

Main Pattern Instructions

1. Butterfly Front Cups

Make two identical cups using Color A and the 3.5 mm hook. The cups are worked from the lower center outward, creating a softly curved triangular shape.

Foundation: Ch 4 and sl st into the first chain to form a ring.

• Round 1: Ch 2, work 8 hdc into the ring. Sl st into the first hdc. (8 sts)
• Round 2: Ch 2, work 2 hdc into each stitch around. Join. (16 sts)
• Round 3: Ch 2, *1 hdc in next st, 2 hdc in following st.* Rep around. Join. (24 sts)
• Round 4: Ch 2, *1 hdc in next 2 sts, 2 hdc in following st.* Rep around. Join. (32 sts)
• Round 5: Ch 2, work 1 hdc in each stitch around. Join. (32 sts)
• Round 6: Ch 2, *1 hdc in next 3 sts, 2 hdc in following st.* Rep around. Join. (40 sts)
• Round 7: Ch 2, work 1 hdc in each stitch around. Join. (40 sts)

Continue increasing evenly if needed until the cup reaches approximately half your desired cup width.

• XS/S: 13–14 cm.
• M: 15–16 cm.
• L: 17–18 cm.
• XL: 19–20 cm.

Fasten off the first cup and repeat for the second cup.

Designer Tip: Keep both cups the same size by counting every round. Small differences become noticeable once the pieces are joined.

2. Butterfly Lace Shaping

Join Color B at the outer edge of the first cup.

• Round 1: Ch 1, sc evenly around the curved edge. Work 3 sc into the bottom point and sl st to join.
• Round 2: Ch 3, sk 1 st, *dc in next st, ch 1, sk 1 st.* Rep around the curved section. Work dc stitches along the lower edge where needed to maintain a smooth shape.
• Round 3: Ch 1, sc into each dc and ch-1 space around.
• Round 4: Join Color A. Ch 1, *sk 2 sts, work 5 dc into next st, sk 2 sts, sl st into next st.* Rep along the upper decorative edge.

Repeat the same edging on the second cup. This creates a row of raised shells resembling delicate butterfly wing details.

3. Joining the Butterfly Cups

Place both cups on a flat surface with the right sides facing upward. Position the inner lower corners together. Using Color A and a tapestry needle, sew the inner edges together for approximately 3–4 cm. For a slightly wider center opening, join only 2 cm. Make sure both cups sit evenly before sewing. The upper edges should remain separate for the neck straps.

4. Lower Lace Body

Join Color A at the lower edge of the joined cups. Work across the bottom edge, inserting your hook evenly.

• Row 1: Ch 3, dc evenly across the foundation edge. Turn.
• Row 2: Ch 3, *dc in next st, ch 1, sk 1 st.* Rep across, ending with dc in the final stitch. Turn.
• Row 3: Ch 3, work dc into each dc and ch-1 space across. Turn.
• Row 4: Ch 3, *sk 1 st, V-stitch in next st, sk 1 st, dc in next st.* Rep across. Turn.
• Row 5: Ch 3, work dc into each dc and ch-1 space across. Turn.

Repeat Rows 2–5 until the lower body measures approximately 8–12 cm, depending on your preferred crop length. For a longer top, continue repeating the lace pattern.

Count Check: Your stitch count should remain consistent across the rows. Add or remove an occasional stitch only when needed to keep the side edges straight.

5. Decorative Butterfly Wing Motifs

Make two small decorative motifs using Color B.

• Round 1: Ch 6 and join with sl st to form a ring.
• Round 2: Ch 3, work 2 dc into the ring, ch 3, sl st into the ring. Repeat the following sequence three more times: ch 3, work 3 dc into the ring, ch 3, sl st into the ring.
• Round 3: Sl st into the first chain space. Ch 3, work 4 dc into the same space, ch 2, sl st into the next space. Rep around.

Fasten off, leaving a long tail for sewing. Make two matching motifs. Attach them near the upper outer corners of the cups to emphasize the butterfly silhouette.

6. Mesh Back Panel

The back panel is worked in rows and creates a flexible, breathable section. Join Color A at one side of the lower body.

• Foundation Row: Ch 3, work dc evenly along the side edge.
• Row 1: Ch 3, *dc in next st, ch 1, sk 1 st.* Rep across. Turn.
• Row 2: Ch 3, work dc into each dc and ch-1 space. Turn.
• Row 3: Ch 3, *V-stitch in next available space, sk 1 space.* Rep across. Turn.
• Row 4: Ch 3, dc across. Turn.

Repeat Rows 1–4 until the back panel reaches the desired width when lightly stretched. For an adjustable fit, keep the back section slightly shorter than your full back measurement because the ties will provide additional flexibility. Fasten off.

Special Techniques and Additional Elements

Butterfly-Inspired Shell Edging

For an elegant finish, work a decorative shell border along the exposed outer edges of both cups. Join Color B at the lower outer corner.

*Sc in next 2 sts, sk 2 sts, work 5 dc into next st, sk 2 sts, sc in next st.* Repeat along the curved edge. At tight corners, work 2 sc into the same space to prevent the edging from pulling inward. Finish with a picot at the top of each shell if desired.

Adjustable Neck Ties

Using Color A and the 3.0 mm hook:

• Foundation: Ch 65.
• Row 1: Sl st into the second chain from hook and each chain across.

Fasten off, leaving a long sewing tail. Make two ties. Attach one tie to the top outer corner of each cup. For a stronger attachment, sew the tie through several stitches rather than securing it to only one loop.

Back Ties

Make two additional ties using the same method. Ch 55–70, depending on your preferred length. Work sl st across and fasten off. Attach one tie to each back corner. These ties allow you to adjust the fit around your body.

Assembly and Finishing

Before assembling everything permanently, lay all the pieces flat and check their proportions.

1. Place the two cups side by side.
2. Sew the inner lower edges together.
3. Attach the lower lace body.
4. Add the mesh back panel.
5. Sew the butterfly motifs onto the outer upper cup areas.
6. Attach the neck ties to the top corners.
7. Attach the back ties to the back panel corners.
8. Weave in all loose yarn ends securely.

When attaching the butterfly motifs, use small, neat stitches around their center and outer edges. Avoid pulling the yarn too tightly because this can distort the lace.

Try on the top before weaving in the final ends. Adjust the ties and check that the cups sit comfortably.

Blocking and Care

Blocking makes a noticeable difference to this project. The lace stitches become more defined, the butterfly shells sit more evenly, and the finished garment looks much more polished.

Wet Blocking

1. Fill a basin with cool or lukewarm water.
2. Add a small amount of gentle wash suitable for cotton.
3. Submerge the top for approximately 10 minutes.
4. Remove it carefully without twisting.
5. Press out excess water using a clean towel.
6. Lay the top flat on a blocking mat.
7. Gently shape the cups, mesh sections, and decorative edges.
8. Pin the lace shells evenly.
9. Allow the garment to dry completely.

Avoid stretching the cups excessively during blocking.

Care Instructions

• Hand wash gently in cool water.
• Avoid harsh detergents and bleach.
• Do not wring or twist.
• Dry flat.
• Never hang the garment while wet.
• Store folded in a clean, dry place.

Fit and Troubleshooting Tips

My cups are curling inward.

Your stitches may be too tight. Try a larger hook or loosen your tension slightly. Blocking can also help smooth minor curling.

The cups look uneven.

Check the stitch counts and measurements of both cups. If one is wider, undo the final round and correct the increases.

The lace body is ruffling.

You may have too many stitches or inconsistent chain spaces. Check the repeat and make sure you are not accidentally increasing.

The butterfly shells look crowded.

Save

Space the shells farther apart by skipping an additional stitch between motifs.

The top feels too loose.

Shorten the back ties or reduce the width of the mesh back panel.

The top feels too tight.

Lengthen the ties and check whether your gauge matches the recommended measurements.

I want more coverage.

Add two or three additional rows of solid dc beneath the cups before beginning the mesh pattern. You can also wear a fitted camisole underneath.

Final Thoughts

I absolutely love how the Monochrome Lace Butterfly Halter Top brings together delicate crochet details and a clean black-and-white color palette.

The butterfly-inspired cups, airy lace body, and adjustable ties make this a fun handmade wardrobe piece that you can customize to suit your style.

Don’t be afraid to experiment with the colors. A black-and-white version looks modern and elegant, while cream and charcoal create a softer vintage-inspired appearance.

Take your time with the shaping, enjoy the little details, and remember that handmade clothing is all about making something that feels special to you.
