PRO Tips for Crocheting a Romper

• Swatch for fit: Rompers require a good fit, especially at the waist and hips. Always crochet a swatch to check gauge before starting the main project.
• Use lightweight yarn: Choose soft, breathable yarn like cotton blends to make it comfortable for warmer weather.
• Customize the top length: I have provided instructions on where to add more rounds for a perfect fit.
• Try on as you go: If you’re making this for yourself, try it on after the top is complete to ensure a good fit before working the shorts section.

Fasten off.

Back Panel

Check fit: Neckline depth.

• Check the neckline length of your piece. 
• If you prefer it extends more, add more rows before shaping the neckline below.
• For a shorter neckline, reduce the number of rows before neckline shaping. 

Join yarn with a sl st to the starting chain in row 1.

The skipped chs from the foundation chs while making the front panel will be used for the next row.

Row 1: Ch 2, 2 dc in same st, *skip next 2 sts, sc in next ch-sp, 2 dc in same ch-sp, repeat from * to end of row, sc in final ch st of row, turn.

• Make sure you have an odd number of rows for the back panel.

Fold lengthwise to have the short ends next to each other. 

Join the sides with a sl st.

Do not fasten off.

Edging

Note: 

The numbers might be different from mine. 

Make sure to check the fit of your shorts as you proceed.

Round 1: Ch 1, sc in each st around the panel, join with a sl st to the beginning ch. 54 (60, 70, 80, 90, 100, 110, 120, 130) sc

Fasten off, join yarn with a sl st to the other open end.

Repeat the edging (rounds 1 – 2) on the other end, do not fasten off.

No need to turn after each round, the shorts look beautiful when made in rounds instead of turning as we did with the top.

Round 1: Ch 2, 2 dc in same ch sp, *sc in next ch sp, 2 dc in next ch sp, rep from * until the end, join with a sl st to the beginning ch. 14 (15, 18, 20, 23, 25, 28, 30, 33) sc/ dc groups

For the prototype, I started a new color from the next round.

Round 2: Ch 2, 2 dc in first sc below, *skip next 2 dc, (sc, 2 dc) in next sc, repeat from * around, sc in last st, join with a sl stitch to the beginning ch 2. 14 (15, 18, 20, 23, 25, 28, 30, 33) sc/ dc groups

Round 8: Repeat round 6. 30 (31, 32, 40, 42, 50, 56, 60, 66) sc/ dc groups

Fit check

• Check the width of the project by measuring the circumference. 
• If it is too tight, repeat rounds 6 – 7 one or two more times.

Rounds 9 – 22: Repeat round 7. 30 (31, 32, 40, 42, 50, 56, 60, 66) sc/ dc groups

Repeating until your piece measures 10 (10, 12, 12, 13, 13, 13, 14, 14)”

Split for Leg Openings

• Place a stitch marker on the 15 (16, 16, 20, 21, 25, 27, 30, 33) sc
• If your count is different from the above, count the number of sc, divide by 2 
• Place a stitch marker at the middle (centre).

Section 3 – Leg Right

Round 1: Ch 2, 2 dc in first sc below, *skip next 2 dc, (sc, 2 dc) in next sc, repeat from * around the sts left unworked, connect with a sl st to the beginning chain. Leave the remaining stitches unworked.

Rounds 2 – 9: Ch 2, 2 dc in first sc below, *skip next 2 dc, (sc, 2 dc) in next sc, repeat from * around, sc in last st, join with a sl stitch to the beginning ch 2.

Fasten off.

Section 3 – Left Leg 

Pass your hook through the right leg’s starting chain and last stitch, and join yarn with a sl st through the two sts. This closes up the gap.

Make a slip stitch to secure the two sts.

Crochet around the sts left unworked while making the right leg.

Round 1: Ch 2, 2 dc in first stitch to your left, skip next st, *(sc, 2 dc) in next sc, skip next 2 dc, repeat from * until the stitch marker, make a slip stitch through the middle of the beginning chain and then join a sl st to the top of the beginning chain.

This last step covers the gap 

Repeat rounds 2 – 9 as with the right leg. 

Fasten off

Sew in all ends.

Joining the top to the shorts

• Pick up the shorts and the top
• Turn both to the wrong side 

• Place the lower end of the top next to the shorts.
• The joining is through the mesh row of the top and the last row of the short. The shells from the last round of the top are to cover the joining. This creates a beautiful cover over the joining. 
• Using either a darning needle or a crochet hook, and either the mattress stitch or the slip stitch, join the upper part of the shorts to the last round of the mesh on the lower end of the top.

Tip for a perfect joining:

• Count the number of stitches on the lower end of the top and the stitches on the last round of the shorts. 
• If the stitches are more on one side, you can join using 2 stitches on one side and one stitch on the other side to give an even joining. Make sure to even these around.

Fasten off. 

Weave in ends.

Block your romper.
