This fitted cropped top with a heart-shaped cutout at the chest delivers pure romantic vibes without drowning you in complicated stitches. You work mostly in single crochet, shape a few key edges, and suddenly that negative space forms a perfect heart right over the bust. Asymmetric button placket, puff sleeves with ruffle cuffs, pointed front hem—the whole thing looks way fancier than the skill level required. Ready to make something that turns heads at brunch? Let’s dive in.
Why This Crochet Top Pattern Works
The dense single crochet fabric gives this top serious structure. It holds its shape, stays opaque, and refuses to stretch out of control the way pure acrylic sometimes does. Cotton or a cotton blend is your best friend here—trust me on that one.
The heart cutout looks intimidating until you realize you’re just shaping two front panels along the inner edges. Place them side by side and the negative space does the rest. No weird stitch tricks, no lace overlays. Just clean decreases and increases.
Then there’s the asymmetric diagonal button band that runs from the right shoulder down to that pointed center-front hem. Seven heart-shaped buttons turn a simple placket into a statement. Romantic and modern at the same time? Yes, please.
Plan on 20 to 30 hours total. Take your time with the shaping sections and check your gauge like your finished bust measurement depends on it—because it does.
Materials You Will Need
Grab roughly 900 to 1100 yards of worsted weight yarn (category 4). Smooth, lightly twisted yarn with good stitch definition wins every time. Cotton-acrylic blend or 100 percent cotton keeps everything structured and breathable.
Solid options:
- Lion Brand 24/7 Cotton in Lavender — 100 percent mercerized cotton, about 5–6 skeins
- Paintbox Yarns Simply DK worked at a tighter gauge — 7–8 skeins if you go that route
- We Are Knitters The Petite Wool in pastel lavender — 6–7 skeins for a softer hand
Hook: US G-6 / 4.0 mm. Adjust if your gauge fights back.
Notions that actually matter:
- 7 heart-shaped shank buttons, around 18 mm, silver or pearl
- Yarn needle, at least 10 stitch markers, measuring tape
- Blocking mat + rust-proof pins
- Sharp sewing needle and matching thread for the buttons
That’s it. No exotic tools required.

Gauge for This Crochet Pattern
20 single crochet stitches = 4 inches / 10 cm
22 rows of single crochet = 4 inches / 10 cm
Skip the swatch and you risk a top that’s either painted on or swimming on you. One stitch off per four inches changes the bust by more than two inches across. Not cute.
Chain 25, sc in the second chain from the hook and across (24 sc). Work rows until the swatch hits at least five inches tall. Block it flat, then measure. Too loose? Drop a hook size. Too tight? Go up one. Simple.
Special Stitches for This Top
You’ll lean on three special techniques.
Puff Stitch (for those dreamy cuff ruffles):
Yarn over, insert hook, pull up a loop to about half an inch. Repeat twice more in the same stitch (six loops total). Yarn over and pull through all six. Chain 1 to close. That’s one puff unit.
Ruffle Row: Work three single crochets into every stitch across. Instant gathered wave. Magic.
Reverse Single Crochet (crab stitch): Work backward along the edge without turning. Insert the hook from front to back into the stitch to the right, yarn over, pull up a loop, yarn over and pull through both loops. Neat corded finish for the button band and hem.
Master these three and the rest is straightforward single crochet.
Pattern Notes Before You Begin
Everything is worked flat in rows unless the pattern says otherwise.
Each row starts with a chain 1 that does not count as a stitch.
Row 1 after the foundation chain is your right side—stick a marker on it.
The button band is picked up later and worked outward from the seamed front.
Collar is a separate flat piece seamed on at the end.
Sleeves are worked flat, seamed into tubes, then shaped at the cap.
Use a smaller hook (US F-5 / 3.75 mm) just for the heart edging—it keeps the cutout edges crisp.
Stitch counts in parentheses are the total after increases or decreases.
Read those twice. They save you from frogging later.
Step by Step Instructions for the Heart Cutout Top
The Back Panel
Start at the bottom hem and work up. Finished size roughly 18 inches wide by 15 inches tall.
Chain 93.
Row 1 (RS): Sc in second chain from hook and across (92 sc).
Rows 2–42: Ch 1, turn, sc across (92 sc).
After row 42 you should be at the base of the armhole—about 7.5 inches tall. Mark it.
Back Armhole Shaping
Row 43: Slip stitch the first five stitches, ch 1, sc across to the last five, leave them unworked (82 sc).
Rows 44–47: Decrease one stitch at each end every row until you hit 74 sc.
Rows 48–64: Straight sc across (74 sc).
Shoulders and neck next: Work the left shoulder over 22 stitches for three rows with a decrease, fasten off. Skip the center 30 neck stitches, rejoin for the right shoulder, and mirror the shaping. Done.
Left Front Panel
This side forms the left lobe of the heart. Chain 47, work 46 sc for 42 rows, then shape the armhole by leaving five stitches and decreasing over the next few rows until you reach 37 stitches.
Heart lobe shaping begins around row 53: decrease on the inner edge for several rows down to 30 stitches, then increase back up to 37. Neckline shaping follows with more inner-edge decreases, finishing the shoulder at 21 stitches.
Right Front Panel
Wider because of the button overlap and the pointed V-hem. Chain 57, work 56 sc for a few rows, then start the V-hem decreases on the inner edge every other row until you settle at 51 stitches. Continue to the armhole, shape it, then mirror the heart lobe decreases and increases on the opposite side. Neckline and shoulder finish the same way, leaving the placket overlap stitches free.
The two front panels side by side create that heart negative space. It’s honestly the most satisfying moment of the whole project.
Assembly and Finishing Tips
Block every piece first. Pin them to the finished measurements on your mat and let them dry completely. This step turns “homemade” into “did you buy that?”
Seam the shoulders with mattress stitch or whip stitch. Side seams next, leaving the armholes open. Switch to the smaller hook and work a clean single-crochet or reverse single-crochet edging around the entire heart cutout.
Seam the sleeves into tubes, shape the caps, and set them in. Add the ruffle cuffs last—those three-sc rows create the perfect soft wave.
Pick up stitches along the diagonal front edge for the button band and work outward. Space the seven heart buttons evenly and sew them on with matching thread and a sharp needle. Secure them well—you’ll be wearing this one a lot.
Size Customization Tips
Written for medium. Going smaller? Drop 4–8 stitches from the foundation chains and work fewer rows before the armholes. Larger? Add the same number of stitches and extra rows. Keep the proportions consistent across all pieces so the heart cutout still looks balanced. Always re-check gauge after any change. FYI, the heart shaping ratios stay the same no matter the size.

FAQ’s
Is this pattern really advanced beginner friendly?
If you can work single crochet, increases, and decreases without crying, you’re good. The shaping looks fancy but it’s just carefully placed sc2tog and 2-sc increases. No complex lace or cables.
What yarn substitutes work best?
Any smooth worsted cotton or cotton-blend. Avoid super soft acrylics that stretch forever. You want stitch definition and structure. IMO the mercerized cottons look the cleanest.
How do I keep the heart edges from curling or looking messy?
Switch to a half-size smaller hook just for the edging round. Work slowly and evenly. Blocking finishes the job.
Can I make the sleeves longer?
Absolutely. Add extra straight rows before you start the sleeve-cap shaping. Keep the ruffle the same so the proportions stay cute.
Do I really need to block everything?
Yes. The dense single crochet fabric relaxes and the heart shape opens up beautifully once blocked. Skipping it is the difference between “cute project” and “wow, did you make that?”
Where can I find heart-shaped buttons?
Most craft stores carry them in the notions aisle, or search online for “18 mm heart shank buttons.” Pearl or silver finishes look especially pretty against lavender.
