The B3 was originally designed for male pilots, so nailing the fit on a woman's frame takes a little know-how. This women's b3 bomber jacket size guide walks you through every checkpoint, so you order once and love it for years.

Why B3 Fit Is Tricky for Women

Unlike fashion bombers cut for women, the B3 has a boxy aviator silhouette with a wide shearling collar. It is supposed to have some room, but too much room swallows a smaller frame. The goal is structured, not sloppy.

Take Your Measurements First

Grab a tape measure and note your bust, waist, shoulder width, and arm length. Compare these against the size chart on the product page, not your usual dress size. Leather does not stretch like knitwear, so numbers matter more here than with most jackets.

Checkpoint 1: Shoulders

The shoulder seams should sit right at the edge of your shoulders. If they droop down your arms, the jacket is too big. If they pull when you reach forward, it is too small. This is the one area you cannot compromise on.

Checkpoint 2: Bust and Chest

You should be able to zip the jacket over a light sweater without the zipper straining. The shearling lining takes up space, so if it zips comfortably over a sweater, the fit is right. Straining means size up.

Checkpoint 3: Waist and Length

A women's B3 should end at or just below your waistband. Longer than that and it starts looking like a coat rather than a bomber. The knit hem should sit flat without riding up when you lift your arms.

Checkpoint 4: Sleeves

Sleeves should end right at your wrist bone. The shearling cuffs add bulk, so slightly shorter is better than slightly long. You want to see a sliver of wrist, not a puddle of cuff.

Should You Size Up or Down?

Between sizes? Size up if you plan to layer thick knits underneath in deep winter. Size down if you want a sharper, more fitted look for milder weather. Most women find their true measured size works best for everyday wear.

Petite Women: Special Tips

If you are under 5'4", look for cropped or shorter B3 styles. A standard length can overwhelm a petite frame. Also check the collar width, an oversized shearling collar can dominate small shoulders, so a slightly narrower collar looks more balanced.

Common Fit Mistakes to Avoid

Do not buy your fashion-jacket size blindly, B3 sizing runs differently. Do not ignore the shoulder fit hoping it will break in, leather softens but shoulders do not move. And do not size up for an oversized look unless the style is designed for it, a sloppy B3 loses its sharp aviator character.
