This clothing size and fit guide covers everything you need to order with confidence — how to measure yourself, how to use our sizing resources, and fit tips for every style.
How to measure yourself
- Chest: Wrap a soft tape around the fullest part of your chest, just under your armpits, keeping the tape level and comfortably snug.
- Waist: Measure around your natural waist (where your body bends), not lower on the hips.
- Hips: Stand with feet together and measure around the fullest part of your hips and seat.
How sizing works at Qualifier Collective
Every product page includes two sizing resources to help you find your best fit:
- Product Measurements – exact garment measurements (chest width, body length, and sleeve length where applicable), taken with the item laid flat. Use these to compare against a shirt or hoodie you already own and love.
- Measure Yourself Guide – step-by-step instructions for getting your own body measurements so you can compare them directly to the garment specs.
We recommend measuring yourself using the guide above, then comparing your measurements to the product chart. If you're between sizes, the fit note on each product page will help you decide which direction to go.
Our size charts and measurement guide provide best-estimate guidance based on your measurements and garment specs. They're helpful tools, not guaranteed outcomes — we can't promise a perfect fit for every body.
Fit tips
- Most styles are designed to fit true to size or slightly oversized. Check the fit note on each product page for anything different (slim fit, boxy, cropped, etc.).
- Some styles (like our Stanley/Stella tees) use EU sizing or run smaller than typical US sizing. Check the product measurement chart carefully — if the garment measurements run small or you're between sizes, we suggest ordering one size up.
- If you're between sizes, choose the larger size for a relaxed fit or the smaller size for a closer fit. When you're right on the border, the fit note on the product page will help you choose.
Returns & sizing policy
Because every item is made to order with print-on-demand, we do not accept returns or exchanges for incorrect sizing. Please use the sizing resources on each product page before ordering. If you're still unsure, email us at marleen@qualifiercollective.com before you buy.
