The Fiona Athletic Set Free Sewing Pattern

Whether you’re cheering from the sidelines, gathering with friends for match day, or heading out for a quick kickaround at the park, the Fiona Athletic Set is ready to score. Inspired by the excitement and  camaraderie of the biggest soccer event of the year, this sporty two-piece set combines athletic functionality with a touch of feminine charm for a look that’s as cute as it is comfortable.

Made from breathable athletic mesh for the jersey and cozy cotton fleece knit for the shorts, the Fiona set is the perfect combination of sporty and soft. The relaxed-fit jersey keeps you cool whether you’re on the move or relaxing after the final whistle, while the fleece shorts offer just the right amount of comfort for everything from morning workouts to weekend lounging.

Best of all, both pieces are beginner-friendly and quick to sew. The jersey is constructed from only four pattern pieces, making it an approachable project for newer sewists looking to build confidence. Customize it in the colors of your favorite team with nearly 20 shades of athletic mesh to choose from, then make it uniquely yours by adding your favorite player’s number, your lucky number, or even your birth year. A delicate lace-trimmed collar adds an unexpected touch of sweetness that sets it apart from a typical athletic top.

The coordinating shorts are equally simple to make and packed with personality. Their sporty silhouette features a short inseam that’s playful without sacrificing comfort, while adjustable drawstring lacing at the side seams allows you to customize the fit and length. The lace-up details echo the feminine feel of the jersey’s collar, tying the entire look together with thoughtful details that make this set stand out both on and off the field.

Cute enough for everyday wear and practical enough for an active lifestyle, the Fiona Athletic Set is ready for everything from pickup games and morning jogs to movie nights and snack-filled watch parties. It may just be the most adorable thing you’ve ever worked out in, and it’s more than ready for grass stains, victory dances, and every goal-worthy moment in between.

Find Your Perfect Fit

The Fiona Athletic Set Sizing Guide is based on the suggested design & wearing ease for this style. You can also choose the size according to your desired finished garment measurements, blending between sizes as needed. Measure the printed patterns to make sure the dimensions are according to the desired fitting and adjust if needed before cutting the fabric. For best results, sew a test garment in a similar fabric to adjust your pattern.

Note: Measurements may vary after adjustments. If using non-stretch fabrics, reference the approximate finished garment measurements chart to choose your size.

Note: Always read all the instructions before cutting the fabric!

How to Sew The Fiona Athletic Set

The instructions provided below are designed to guide you through sewing the Fiona Athletic Set from start to finish.

 Tips for Sewing with Mesh Jersey and Fleece-Backed Cotton Knit

⇒ Sew both materials with a stretch needle or ball point needle to prevent skipped stitches and thread pulls in the fabric.
⇒ For the fleece-backed knit, make sure that your grainline is going perpendicular to the direction of stretch in the fabric.
⇒ Launder both fabrics before cutting out the pattern.

Step 2

ATTACH SHORTS POCKETS

1. Place the wrong side of the back pockets on the right side of the back shorts pieces with the bottom edge of the pockets laying parallel with the bottom hem of the shorts. I put my pockets so that they were evenly spaced between the side and crotch seam and the hem and waistline seam.

3. Topstitch around the sides and bottoms of the pockets to attach them to the backs of the shorts.

Step 3

2. Evenly space out the elastic loops along the right side of the side seam of the back of the shorts as shown in the photo below. Make sure to leave enough space on the top of the shorts for the waistband and the bottom of the shorts for the hem when placing the elastic loops.

Step 8

WAISTBAND

2. Poke two holes with an awl on either side of the center front of the shorts at the waistline for the drawstrings.

Step 9

DRAWSTRINGS & LACES

1. Cut two strips of fabric that are the length of your fabric front selvage to selvage and 1.5 inches wide.
2. Fold the strips in half longways and sew them right sides together.
3. Flip the tubes right sides out with a loop turner.
4. Cut one of the strips in half so that it can be used on either side of the shorts side seams.

Step 10

INSERT LACES

1. Insert one of the drawstrings into the waistband channel using a safety pin to feed it through the opening of the tunnel that you made with the awl in step 8.
2. Lace the drawstrings back and forth in a corseted pattern through the elastic loops at the side seams of the shorts.
3. Tie knots at the ends of all the drawstrings.

Step 11

GOLD NUMBERS

1. Following the instructions on the Heat & Bond Web Adhesive, peel off the backing to reveal the sticky side of the web adhesive.
2. Place the sticky side of the web adhesive to the wrong side of the imitation latex.
3. Place a piece of muslin over the web adhesive and then press it to the imitation latex with high heat and no steam. Let it sit and cool for a second before removing it from the ironing board.
4. Place the numbers (and letters, if you choose) on the right side of the imitation latex.
5. Hold the number stencils in place with pattern weights and carefully cut around them with a rotary cutter or X-acto knife.

Step 12

ADHERE NUMBERS

1. Place the paper side of the numbers on the front of the jersey and center them.
2. Peel the paper off the back of the numbers and place them back onto the front of the jersey.
3. Place muslin over the numbers then iron them to the jersey with the iron on high heat and no steam.
4. Let the numbers cool before removing them from the ironing board.
