Let's get started!

Drafting the Pattern from the Basic Sloper Knit T-shirt Pattern

• Step 1: Draw a line to divide the Knit-T-shirt Sloper into 2 panels. Start at the midpoint of the shoulder, pass the line through the midpoint of the bust, then curve it in a straight line to the hem.
• Step 2: Draw a horizontal line across the pattern at the nape-to-waist measurement plus 1cm.
• Step 3: Cut the pattern along the panel line into 2 pieces. Trace these pieces onto temporary pattern paper, such as Spunbon.
• Step 4: On the side panel, curve the side seam in by 2.5cm at the waistline. Flare the line out at 2.5cm at the hemline. Draw the line to desired length.
• Step 5: Curve the line on the front of the side panel in at the waist by 1cm. Flare the line out at 2.5cm at the hemline. Draw to desired length.
• Step 6: Curve the outside line of the center panel in at the waist by 1cm. Curve the line outward to flare at the hemline by 2.5cm to desired length.
• Step 7: Draft the V neck facing using this tutorial. Add seam allowance and cut out the new pattern.
• Step 8: Trace the sleeve onto temporary pattern paper, such as Spunbon.
• Step 9: Mark a point on the fold line to the length where you’d like your sleeve.
• Step 10: Draw a line to a point 2.5 cm inside the underarm line to form a point.
• Step 11: Join the underarm point to the underarm.
• Step 12: add seam allowance and cut out the pattern.

Cutting the Pattern from the Basic Sloper Knit T-shirt Pattern



1. Step 1: Use light weight jersey fabric for this design, such as cotton knit or Bon Bon. You’re looking to use a fabric that will drape well and fall effortlessly into a pretty flare.
2. Step 2: Cut 2 center back/front panels. Cut 4 side panels—two for the left hand side and 2 for the right. Cut a pair of sleeves. Cut the v-neck facing.
3. Step 3: Cut the front mid-panel neckline for the v-neck.

Sewing the New Fit and Flare T-shirt Pattern



Use an overlocker or Serger to sew your t-shirt.

1. Step 1: Sew the back side panels to the center-back panel, right sides together.
2. Step 2: Sew the front side panels to the center-front, right sides together.
3. Step 3: Neaten the back neckline by overlocking the edge. Neaten the facing by overlocking the edge.
4. Step 4: Sew the facing to the front neck edge. Turn the facing to the right side.
5. Step 5: Hem the back neck edge.
6. Step 6: Sandwich the back neck side edge in between the side edge of the front neck and sew the back to the front at the shoulder seam.
7. Step 7: Notch the midpoint of the armhole edge of the sleeves. Pin in place to the shoulder seam.
8. Step 8: Sew the sleeves to the main body of the top, easing to fit smoothly.
9. Step 9: Sew to top together at the side seams and under the sleeves in one fluid movement.
10. Step 10: Hem as desired. One of the nicest finishes for this top is a lettuce frilled hem. A lettuce hem is easy to achieve using a differential feed overlocker : set the differential feed to the smallest stitch and pull the hem to stretch as you sew and the edge will frill beautifully.
11. Step 11: Steam press and wear your custom made fit and flare t-shirt top.
