Size & Fit Guide
Find Your Best Fit
At Sideline Society, we carefully curate apparel from a variety of trusted boutique brands. Because each manufacturer has its own sizing and fit, there isn't a one-size-fits-all chart for every item.
This guide is designed to help you understand general sizing, fit styles, and boutique denim recommendations. For the most accurate sizing information, always refer to the Fit & Sizing section on each individual product page, where you'll find recommendations specific to that item.
How to Measure Yourself
For the best fit, use a soft measuring tape and compare your measurements to the size recommendations on each product page.
Bust
Measure around the fullest part of your bust while keeping the tape level.
Waist
Measure around your natural waistline, just above your hips.
Hips
Measure around the fullest part of your hips while standing with your feet together.

Frequently Asked Questions
Why doesn't every product use the same size chart?
We curate apparel from multiple boutique brands, and sizing can vary slightly between manufacturers. That's why we include personalized sizing recommendations on each product page.
I'm between sizes. What should I do?
Check the product's Fit & Sizing section first. If the garment has stretch, you may prefer the smaller size. If it has little or no stretch, sizing up is often the better choice.
How do your graphic tees fit?
Most graphic tees feature either a relaxed unisex fit or a retail fit. Each product page will indicate whether the shirt runs true to size or has a more oversized or fitted silhouette.
What if I still need help?
We're happy to help! Reach out before placing your order, and we'll recommend the best size based on the specific item you're interested in.
