👖 Denim Fit Guide
Finding Your Perfect Pair
At Sideline Society, we believe shopping for denim should feel simple—not stressful.
Boutique denim often fits differently than department store jeans because of differences in fabric, stretch, and construction. The good news? Once you know what to look for, finding your perfect pair becomes much easier.
This guide is designed to help you confidently choose your best starting size. Then, be sure to check the Fit & Sizing section on each product page, where we provide recommendations specific to that style.
STEP 1
Start With Your Typical Jean Size
Use your normal department store jean size as your starting point.
| Women's Size | Boutique Denim Size |
|---|---|
| 0 | 24 |
| 2 | 25 |
| 4 | 26 |
| 6 | 27 |
| 8 | 28 |
| 10 | 29 |
| 12 | 30 |
| 14 | 31 |
| 16 | 32 |
| 18 | 33 |
This is your starting point—not necessarily your final size.
STEP 2
Find Your Fit
❤️ I like my jeans fitted.
Choose the smaller size if the denim has high stretch.
Perfect if you love a sculpted, body-hugging fit.
🤍 I like a classic everyday fit.
Choose your normal size.
This is the recommendation for most customers.
☁️ I like a relaxed fit.
If you're between sizes—or if the denim has little stretch—consider sizing up.
Great for boyfriend, barrel, or relaxed styles.
