Quick Answer

Yes, Fabletics sizing tends to run slightly small — especially in leggings and high-compression styles.
If you're between sizes, going one size up usually provides a more comfortable fit.

1. How Fabletics Sizing Typically Fits

Based on fit testing from OEM manufacturing work:

• Leggings: run slightly small due to compression
• Sports bras: true-to-size but snug
• Tops: generally true-to-size
• Shorts: slightly small for curvier bodies
• Outerwear: true-to-size

Why:
Fabletics uses mid–high compression knits that naturally fit tighter than lifestyle activewear.

2. Why Some Shoppers Feel Fabletics Runs Small

Main reasons:

✔ Compression fabric

Their leggings are engineered to be supportive, which reduces stretch ease.

✔ High waistbands

More structure means less flexibility in waist and hip areas.

✔ Body type differences

Athletic builds fit better; curvy bodies may feel restricted.

✔ Heavy knit density

Performance fabrics feel tighter than Lululemon’s lighter blends.

• body-contouring seam placements

These design choices naturally make garments fit smaller than lifestyle activewear.
