Hi @alexandria_tale, Here is an example of a circle skirt which is fitted at the waist:

This circle skirt has a larger initial waist circumference, which results in a larger circumference for abdomen and hips. This is a good approach for someone who is an XXXL, with a large upper abdomen and large hips. The enlarged waist must be taken in with darts.

The waistline has wearing ease equivalent to adding 1" to a 24" waist–> (1/24) = 0.042

**(waist_circ * 1.042)**

It also has 20% extra to accommodate the client’s body shape:

(waist_circ * 1.042) + (waist_circ * 1.2) = **(waist_circ * 1.242)**

Convert this to use the front measurements and back measurements *waist_arc_f* and *waist_arc_b*. Especially with persons who are in the larger sizes, the front waist is not the same as the back waist. Substituting waist_circ with 2*waist_arc_f, the circumference or diameter formula becomes:

(waist_circ * 1.242) = **( ( 2 * waist_arc_f ) * 1.245 )**

Plugging this into ( d = 2 * r * _pi ) and solving for r:

**r = ( (waist_arc_f * 1.245) / (_pi) )**

The waistline begins at **r** away from point A.

Use Point from distance and Angle. Origin = A, Length = (( waist_arc_f * 1.245 ) / _pi ), Angle = 270
Create A2 using this length, and points A3 and A4 exactly the same as for the regular circle skirt.

Create the dart centers:

Points A7 & A8 are created with Point Intersect Curve and Axis, at angles 300 & 330.

Create the dart sides:

The darts are created using the sub-arcs which were created by A7 & A9 along arc Arc_A_4.
The excess amount at the waistline is 20%, or 0.20. ( 0.20 / 4 ) = **0.05**.

Points A11, A12, A13, and A14 are ( waist_arc_f * 0.05 ) away from A7 and A9 along Arc_A_4.

Create the dart points:

Points A8 an A10 are created using the Point along Line tool, using Line_A_A7 and Line_A_A9. They are about 2/3rds, or 0.6 of *waist_to_hip_f* which was used to create A3, so **Length = 0.6 * Line_A1_A3**.

Create the dart legs:

The curved darts are created using the Simple Curve tool:

Repeat the above instructions to create the back draft. Then flip vertically. You will have two pattern pieces, sew them with side seams.
