Why scaled-up sizes fail
A straight-size pattern grows in every direction at the same rate. Bodies do not. Going from a size 8 to a 20 adds far more at the bust, waist, and upper arm than at the shoulder or neck. A scaled-up jacket ends up with a shoulder seam hanging off the shoulder, a sleeve that is too long, and a front that still gapes. That is why the shoulder, bust and upper-arm measurements matter most.
Where it should sit
Shoulders
The seam lands on the bone at the top of your arm. Half an inch past is fine on an oversized style; an inch past on a fitted style means the size is too big everywhere else.
Bust
Zipped, you should be able to take a full breath and slide a flat hand inside. If the zip bows outward, size up. Leather softens but it will not gain two inches.
Back
Cross your arms in front of you. Tight across the shoulder blades means the back yoke is too narrow, which no amount of wear will fix.
Arms
Bend your elbow to ninety degrees. The sleeve should not pull at the upper arm or ride up past the wrist bone. Compare the sleeve length in the size guide with your own arm measurement.
Hem
The ribbed hem sits at the top of the hip, where your waist is widest, and rests there without riding up. A hem that lands at the fullest part of the hip will flip up when you sit.
How to measure
- Bust: around the fullest part, tape level, wearing the bra you will wear with the jacket.
- Waist: around the natural waist, where you bend sideways.
- Hip: around the fullest part, feet together.
- Upper arm: around the fullest part of your arm, relaxed.
- Compare to the size guide. If you are between sizes at the bust, go up; if between at the hip only, stay.
Oversized or fitted?
Some cuts are roomier through the body and others sit closer to it. The Roselyn is relaxed, while the Noir Arden is cropped and streamlined and the Aurelia is structured with an elasticated hem. Neither is more flattering; they are different outfits.
