Nothing completes a summer outfit quite like a stylish sun hat. If you’ve ever wanted to create a hat that’s both elegant and breathable, this is the pattern for you! Inspired by the gorgeous two-toned hat you saw, this design combines a classic solid crown with a beautifully lacy, scalloped brim.
The hat is worked from the top down, so you can easily customize the fit as you go. The main body uses a dense single crochet stitch for a sturdy and structured crown, while the brim introduces a delicate lace pattern that’s perfect for warm weather. This project is a fantastic way to practice your crochet skills and create a timeless accessory that will be a favorite for years to come.
Let’s grab our yarn and hooks and get ready to crochet some serious style!

Materials You’ll Need:
- Yarn: Approximately 200-250 yards of a Worsted Weight (Aran/10 ply) yarn. A cotton or cotton blend will provide great stitch definition and is comfortable to wear.
- Main Color (MC): Approx. 150-180 yards (e.g., the teal blue in the image).
- Accent Color (AC): Approx. 50-70 yards (e.g., the cream/white in the image).
- Crochet Hook: 4.0 mm (G/6) or size needed to obtain gauge.
- Stitch Marker: Essential for working in continuous rounds.
- Yarn Needle: For weaving in ends.
- Scissors
Gauge:
Gauge is crucial for a well-fitting hat!
- Using single crochet with your chosen yarn and hook: 18 stitches and 20 rounds = 4 inches (10 cm).
Please make a small swatch to check your gauge. If your swatch is too large, try a smaller hook. If it’s too small, try a larger hook.

Pattern Notes:
- This hat is worked from the top down in continuous rounds. Do not join rounds unless specified. Use a stitch marker to keep track of the first stitch of each round.

- When changing colors, complete the last yarn over of the last stitch of the previous round with the new color.
Part 1: The Crown of the Hat
We’ll start with a solid, flat circle and then work our way down to the brim.

With Main Color (MC):
Round 1: Make a magic ring. Sc 6 into the ring. Do not join. PM in the first sc. (6 sc)
Round 2: Inc in each st around. (12 sc)
Round 3: (Sc in the next st, inc in the next st) 6 times. (18 sc)
Round 4: (Sc in the next 2 sts, inc in the next st) 6 times. (24 sc)
Round 5: (Sc in the next 3 sts, inc in the next st) 6 times. (30 sc)
Round 6: (Sc in the next 4 sts, inc in the next st) 6 times. (36 sc)
Round 7: (Sc in the next 5 sts, inc in the next st) 6 times. (42 sc)
Round 8: (Sc in the next 6 sts, inc in the next st) 6 times. (48 sc)
Round 9: (Sc in the next 7 sts, inc in the next st) 6 times. (54 sc)

- To adjust crown size: Continue increasing in this manner until your crown measures approximately 6-7 inches (15-18 cm) in diameter, or the size that fits the crown of your head.
Rounds 15-25 (or desired length): Sc in each st around.
- Work in continuous rounds, moving your stitch marker up with each round.
- For the image, about 10-12 rounds of straight single crochet creates the deep crown of the hat.
- To adjust height: Try on the hat as you go. You are done with this section when the sides of the hat reach the top of your ears.
Part 2: The Brim
Now we will transition to the lacy, scalloped brim.

Round 26: (Sc in the next 2 sts, inc in the next st) 28 times. (112 sc)
- This increase round provides the initial flare for the brim.
Round 27: Ch 3 (counts as first tr), tr in the same st. Ch 2, sk next 3 sts. (2 tr in next st, ch 2, sk next 3 sts) 27 times. Join with a sl st to the top of the beginning ch 3. (56 tr sts)
- This creates the base for our lacy pattern.
Round 28: Ch 3 (counts as first tr), tr in the same st. Ch 2. (2 tr in next st, ch 2) 27 times. Join with a sl st to the top of the beginning ch 3. (56 tr sts)
Round 29 (Last MC Round): Ch 1, sc in each st around (work 2 sc in each ch-2 sp). Join with a sl st to the first sc. (112 sc)
Change to Accent Color (AC):
Round 30 (Scalloped Edge): Ch 1. Sc in the first st. Sk next st, (dc, ch 1, dc) in next st, sk next st, sc in next st. Repeat from … around. Join with a sl st to the first sc.
- This creates a simple but beautiful scallop.
Round 31 (Final Scalloped Edge – optional): Ch 1. Sc in the first st. Sk next st, (dc, ch 1, dc) in next ch-1 sp, sk next st, sc in next st. Repeat from … around. Join with a sl st to the first sc.

FO, weave in all ends securely.
