Jett jacket: Design Options

Conditional Options

Armhole depth factor (legacy)

Controls the depth of the armhole. Higher values make a deeper armhole. This option only applies to the legacy (v2) way of calculating the armhole depth.

• Type: Percentage
• Default: 55%
• Minimum: 50%
• Maximum: 70%

This option controls the depth of the armhole.

Armhole depth

Controls the depth of the armhole. Higher values make a deeper armhole.

• Type: Percentage
• Default: 2%
• Minimum: -10%
• Maximum: 50%

This option controls the depth of the armhole.

note

This option applies to the new v3 way of calculating the armhole depth. If you enable the legacy armhole depth option, this option will not apply, but instead it’s legacy version armhole depth factor will.

Construction

Ribbing

Whether to generate a waistband and cuffs made of stretchy ribbing

• Type: Boolean
• Default: true

Whether to draft a waistband and cuffs with stretchy ribbing

Waistband extension percentage

How wide to make the button placket extension at the ends of the waistband

• Type: Percentage
• Default: 5%
• Minimum: 0%
• Maximum: 20%

Determines the width of the waistband extension pieces

Ribbing stretch

Use this to adapt the pattern to how stretchy the ribbing that you are using is.

• Type: Percentage
• Default: 15%
• Minimum: 0%
• Maximum: 30%

Determines how far the ribbing should be stretched at the waistband and cuffs. Change this depending on how stretchy your fabric is.

Yoke

Whether to draft the back panel with a yoke across the shoulders. The yoke does no extra shaping right now, so this doesn’t affect the fit.

• Type: Boolean
• Default: true

This option controls whether the back is drafted as one piece, or with a yoke. The yoke does no additional shaping right now.

Fit

Biceps ease

The amount of ease at your upper arm. Note that while we try to respect this, fitting the sleeve to the armhole takes precedence over respecting the exact amount of ease.

• Type: Percentage
• Default: 15%
• Minimum: 0%
• Maximum: 50%

The amount of ease at your upper arm.

Chest ease

The amount of ease at your chest.

• Type: Percentage
• Default: 15%
• Minimum: 0%
• Maximum: 50%

This option controls the ease at your chest.

Collar ease

The amount of ease around your neck

• Type: Percentage
• Default: 2%
• Minimum: 0%
• Maximum: 50%

Controls the amount of ease at your collar/neck.

Cuff ease

This option controls the ease at your wrist.

Hips ease

The amount of ease at your hips

• Type: Percentage
• Default: 8%
• Minimum: 0%
• Maximum: 50%

This option controls the ease at your hips.

Shoulder ease

The amount of ease at your shoulder. This increases the shoulder to shoulder distance to accommodate additional layers or thickness.

• Type: Percentage
• Default: 0%
• Minimum: -2%
• Maximum: 6%

Controls the amount of ease on the shoulder to shoulder measurement.

This option allows you to create some extra ease at the shoulders which shifts the shoulder seam more outwards and off the shoulder. Thereby creating extra room for extra layers of clothing underneath, or more shaped/padded shoulders.

Belly

bellyAdjustmentX

undefined

• Type: Percentage
• Default: 40%
• Minimum: 5%
• Maximum: 95%

Controls where the full belly adjustment is positioned horizontally

Use full belly adjustment

This widens the front piece to account for a waist wider than the hip measurement. To use this, make sure to take the waist measurement at the fullest part of your belly

• Type: Boolean
• Default: false

Determines whether to make a full belly adjustment to the front piece. This only comes into effect if the waist measurement + waist ease is enough to need it.

waistEase

undefined

• Type: Percentage
• Default: 10%
• Minimum: 0%
• Maximum: 50%

This option controls the ease at your waist. This only comes into effect if Use Belly Adjustment is on.

Bust

Bust dart (EXPERIMENTAL)

Draft the pattern with a full bust adjustment and a bust dart. This only takes effect if Draft for High Bust is true. This option isn’t guaranteed to preserve the armhole or side seam lengths. Proceed with caution.

• Type: Boolean
• Default: false

Determines whether to draft a bust dart, and what method to use to create it

Bust dart offset

How close to the bust apex to start the bust dart

• Type: Percentage
• Default: 25%
• Minimum: 5%
• Maximum: 90%

How far away from the bust apex to start the bust dart

Draft for high bust

Draft the pattern using the high bust measurement if it is available, instead of using the chest measurement. This can result in a more fitted garment for people with breasts. (Please note that no additional adjustments or shaping is performed. Further manual adjustments may be needed for those with a larger difference between high bust and chest measurements.)

• Type: Boolean
• Default: false

Draft the pattern for the high bust measurement (if available) rather than the (full) chest. This will result in a more fitted garment for people with breasts.

Full bust ease

Allows you to independently control the ease in the bust adjustment without affecting the armscye

• Type: Percentage
• Default: 10%
• Minimum: 0%
• Maximum: 50%

Back neck cutout

How deep the neck is cut out at the back

• Type: Percentage
• Default: 5%
• Minimum: 2%
• Maximum: 8%

Controls how deep the neck opening is cut out in the back of the garment. In other words, increasing this will shift the neck opening to the back.

Front armhole extra cutout

How much do you want the front armhole to be cut out deeper than the back.

• Type: Percentage
• Default: 0.2%
• Minimum: 0%
• Maximum: 0.5%

Controls how much the front of the armhole is cut deeper into the garment than the back.

Since the human shoulder is more rounded at the front of the body, the sleeve(cap) is more rounded there too, and the armhole is typically cut deeper into the front of the garment than the back. This option controls how much deeper.

Legacy armhole depth

Enable this option to use the legacy way to calculate the armhole depth (using biceps circumference) rather than the v3 way (using the waist to armpit measurement)

• Type: Boolean
• Default: false

This option allows you to use the legacy way of calculating the armhole depth in Brian.

The legacy (v2) way used the biceps circumference to estimate the armhole depth.

The v3 way instead uses the waist to armpit measurement to locate the bottom of the armhole.

If you enable this option, the Brian block will revert to the v2 way of calculating the armhole depth.

undefined

undefined

• Default: 2%
• Minimum: 0%
• Maximum: 4%

How far to draft the corners of the pocket bag from the pocket opening

Shoulder slope reduction

• Type: Percentage
• Default: 0%
• Minimum: 0%
• Maximum: 80%

Reduces the shoulder slope to create extra room for shoulder padding.

Sleeve width guarantee

Controls how much of the sleeve width will be guaranteed. This determines how much we can alter the sleeve width to fit the sleeve in the armhole.

• Type: Percentage
• Default: 90%
• Minimum: 25%
• Maximum: 100%

We first draft the arm opening, then we draft a sleeve to fit it.

When all goes well, the sleeve fits perfectly, and this option is not relevant. However, if/when the sleeve does not perfectly fit the arm opening, we need to adapt it.

Since the shape and height of the sleevecap are more important than the width, we tend to prefer adjusting the width to fit the sleevecap.

To avoid the sleeve getting too narrow, we only adapt a portion of the sleeve width. This option allows you to control how much of the sleeve width is guaranteed. Increasing this option will allow us less of the width to play with to fit the sleeve. This way, the resulting sleeve will be closer to the theoretical sleeve width, and we will instead modify (more of) the sleevecap height to fit the sleeve.

Sleevecap

Sleevecap back X

Controls the placement of the sleevecap back pitchpoint on the X-axis (horizontal)

• Type: Percentage
• Default: 60%
• Minimum: 35%

Sleevecap ease

The amount by which the sleevecap seam is longer than the armhole seam.

• Type: Percentage
• Default: 0%
• Minimum: 0%
• Maximum: 10%

This option determines the amount of ease at the sleevecap.

note

The amount of sleevecap ease determines how the sleeves rolls from the shoulder. More ease makes the sleeve curl into the seam as you see on suit jackets. Less ease makes the sleeve lie flat.

For light fabric or knits, you want little to no sleevecap ease. For heavier woven fabrics, you need more sleevecap ease.
