This crochet sweater dress pattern is an original top-down adult garment with a shallow circular yoke, a small slate-blue and sage sprig band, a solid waist transition and a gently flared skirt. Long plain sleeves and two side slits keep the silhouette comfortable. It is a dress, not a cardigan or a pullover-length sweater.
Pattern Details
- Adult sizes S (M, L, XL); finished bust 36 (40, 44, 48) inches and hip 44 (48, 52, 56) inches.
- Shoulder-to-hem length 36 (37, 38, 39) inches; add or remove plain skirt rounds for a custom length.
- Gauge is 18 hdc and 14 joined rounds = 4 inches after washing and drying.
- Intermediate level, US terms, worked from the neckline downward.
Why You’ll Love This Dress
The circular yoke keeps shoulder seams out of the construction, and the single colorwork band gives the garment its Nordic character without carrying several colors through the whole skirt. A-line increases are separated from the chest shaping, so you can measure the bust and hip independently. The side slits make a long hem easier to walk in and can be lengthened without changing the yoke.
Materials
- Worsted washable yarn: about 1,650 (1,850, 2,100, 2,350) yards oatmeal, 100 yards slate blue and 90 yards sage.
- 4.5 mm hook for the fabric; 4 mm hook for ribbing; 18 locking stitch markers.
- Waste yarn, tape measure, yarn needle and scissors.

Gauge, Measurements, and Planning
Make a 6-inch hdc swatch, wash and dry it exactly as the dress will be cared for, then measure its center. The target is 18 stitches and 14 rounds per 4 inches. Choose the size whose finished bust is about 2 inches larger than the body bust. The hip measurements provide approximately 4 inches of ease. Worsted yarn varies widely: if the swatch feels board-like, try a larger hook and recheck both stitch and round gauge. Record the yoke depth before separating sleeves; it should reach just below the underarm.
Abbreviations and Colorwork Notes
Ch is chain, hdc is half double crochet, sc is single crochet, sl st is slip stitch, and rnd is round. Beginning chains never count. Place 18 markers evenly and work one hdc increase at each marker on increase rounds, adding 18 stitches. On the motif band, use O for oatmeal, B for blue, and G for sage. Each chart cell is one hdc; read each written sequence from right to left and repeat it around the round. Catch floats every four stitches, keep them relaxed, and do not trap a marker inside a float.
The six-round original sprig chart is: Rnd 1, repeat O O O G O O O O O O; Rnd 2, repeat O O G O G O O O O O; Rnd 3, repeat O G O O O G O O O O; Rnd 4, repeat O O O B O O O O O O; Rnd 5, repeat O O B B B O O O O O; Rnd 6, repeat O B B B B B O O O O. For sizes with a wider marker section, center this ten-stitch motif in each section and work oatmeal in any extra stitches on both sides.
Instructions
Neck and circular yoke
- With oatmeal and the 4.5 mm hook, ch 72; join without twisting and work one hdc in each chain. Mark the first stitch: (72 sts).
- Place 18 markers evenly, one at each increase position. Work one plain hdc round, then increase at every marker on alternate rounds. The count rises by 18 each increase round.
- Continue until the yoke has 252 (288, 324, 360) stitches for S (M, L, XL). The full sequence is (90 sts), (108 sts), (126 sts), (144 sts), (162 sts), (180 sts), (198 sts), (216 sts), (234 sts), (252 sts), (270 sts), (288 sts), (306 sts), (324 sts), (342 sts), and (360 sts). Stop at the size count. Work the six-round chart band when the yoke first reaches 180 (216, 252, 288) stitches; resume increases afterward.
- Work until total yoke depth from the neckline is 8 (8.5, 9, 9.5) inches. On the final round, place markers for front 73 (82, 91, 100), sleeve 53 (62, 71, 80), back 73 (82, 91, 100), sleeve 53 (62, 71, 80). These values total 252 (288, 324, 360).

Separate sleeves and establish the waist
- Work across the front, chain 8 for the underarm, skip the first sleeve and hold those sleeve stitches on waste yarn; work the back, chain 8, skip and hold the second sleeve, then join. Body counts are 162 (180, 198, 216) stitches including both underarm chains.
- Work hdc rounds even until the body measures 10 inches from the underarm. Keep the side markers opposite one another. This is the waist transition; do not decrease the chest.
- For the A-line skirt, increase 4 stitches on every fourth round: work 2 hdc in the stitch before and after each side marker, and repeat at both sides. Work these four increases on 5 (6, 7, 8) increase rounds, leaving 182 (204, 226, 248) stitches. Count every increase round.
- Continue even until shoulder-to-hem length is 32 (33, 34, 35) inches, stopping 4 inches before the planned full length.
Side slits and hem
- Divide at the two side markers and work front and back panels separately in turned hdc rows. Keep the first and last 3 stitches in sc for a firmer slit edge.
- Work each panel until the full shoulder-to-hem measurement is 36 (37, 38, 39) inches. This leaves a 4-inch opening at each side. For a shorter slit, work fewer flat rows; make the front and back panels the same length.
- With the 4 mm hook, work 6 rounds of back-loop hdc ribbing along each panel hem. Add 1 sc evenly along each slit edge and fasten off.

Sleeves and neckline
- Return held sleeve stitches to the 4.5 mm hook, join yarn at the underarm and work around the sleeve plus 8 underarm chains: 61 (70, 79, 88) stitches. Work joined rounds to 17 inches from the underarm, decreasing 2 stitches evenly every sixth round 10 (11, 12, 14) times to 41 (48, 55, 60) stitches.
- Change to the 4 mm hook and work 8 rounds of back-loop hdc ribbing. Fasten off. Repeat for the second sleeve, matching its round count and length.
- At the neckline, join oatmeal and work one round of sc evenly around the foundation, then 5 rounds of back-loop hdc. Fasten off without pulling the neck edge tight.
Assembly and Shaping
Lay the dress flat and align the front and back side markers. The A-line increases should sit in four straight columns, two near each side. If the dress twists, recount the body stitches before blocking. A steamer held above the fabric can relax the hdc texture, but do not stretch the yoke chart or lengthen one panel more than the other.

Finishing
- Weave yarn tails on the wrong side, splitting long floats so they cannot snag.
- Wash according to the yarn label and dry flat; shape the bust, hip and side slits to the listed measurements.
- Try the dress over the intended underlayer and walk in it before fastening every tail. Increase slit height only if the hem restricts stride.
- Record the actual finished bust, hip, sleeve and length measurements; this pattern is not physically wear-tested.
Tips
- Use a large swatch because the drape of a skirt differs from a small square.
- Keep the 18 increase markers in place until the yoke is divided; this makes the chart repeat easier to track.
- Pin the side slits before adding ribbing, checking that both openings finish at the same height.
- For a longer dress, add even rounds before opening the side panels and use matching yarn for the hem.
Frequently Asked Questions
Can I make the skirt fuller?
Yes. Add one additional four-stitch increase round every four rounds, then check the hip measurement on a blocking surface before continuing.
Can the colorwork be made in a single color?
Yes. Work all chart cells in oatmeal for a textured solid yoke, or use surface embroidery after finishing. Keep the same stitch count and yoke depth.
How do I adjust the length?
At the stated round gauge, about 14 joined rounds add 4 inches. Add or remove even rounds before dividing the hem into front and back panels; keep both side slits equal.
Conclusion
This long A-line garment combines a circular sprig yoke, a measured waist transition, a gradually wider skirt and matched side slits. Check your washed gauge, count the yoke increases, and compare the finished bust and hip to your own measurements before wearing.
