Quick Answer

The Lululemon jacket most associated with the “BBL effect” is the Define Jacket.

From my experience working with activewear manufacturing, pattern engineering, and fit development, this effect isn’t accidental. It’s the result of strategic seam placement, fabric stretch, and a tapered waist design that visually enhances curves.

1. What People Mean by the “BBL Effect”

When people talk about the “BBL effect” in clothing, they’re not talking about surgery — they mean a visual illusion.

In simple terms, the BBL effect means:

• a smaller-looking waist
• more pronounced hips and glutes
• a lifted, hourglass silhouette

This effect is created through design, not padding.

2. The Lululemon Jacket That Creates the BBL Effect

The jacket people are referring to is the Define Jacket.

Official brand reference:
👉 Lululemon

The Define Jacket is famous for:

• a tightly contoured waist
• curved princess seams
• a longer torso line
• body-hugging stretch fabric

These features combine to visually push curves outward while pulling the waist inward.

3. Why This Jacket Shapes the Body This Way

From a technical perspective, the shaping comes from three main design choices.

1. Seam Placement

• vertical princess seams curve inward at the waist
• seams angle outward over the hips
• this creates contrast between waist and lower body

2. Fabric Stretch & Recovery

• high-stretch fabric hugs without flattening
• strong recovery prevents sagging
• fabric follows natural curves instead of compressing them

3. Length & Proportion

• hip-length cut elongates the torso
• makes the waist appear smaller relative to hips

My honest take:
This jacket doesn’t add volume — it reframes proportions.

4. Define Jacket vs Other Lululemon Jackets

Key takeaway:
If your goal is shaping and curves, the Define Jacket stands alone.

5. Who This Jacket Is Best For (and Who It’s Not)

The Define Jacket is ideal if you:

• want a snatched waist look
• like fitted, sculpted silhouettes
• wear leggings or flared yoga pants
• want an outfit that enhances curves

It may not be ideal if you:

• prefer oversized or relaxed fits
• dislike tight clothing
• want heavy layering or winter warmth

Straight answer:
The “BBL effect” only works if you want a fitted look.
