Size Guide

Find Your Perfect Fit

Bonnie Boom tees are designed with a flattering women's fit - not boxy, not oversized. Because our garments are cut to complement the body rather than swallow it, we recommend choosing your size based on your body measurements and referring to the size chart on each product page.

How We Measure Our Garments

All measurements are taken with the garment laid flat on a surface. The four key measurements used across our collection are Chest, Shoulder Width, Sleeve Length and Garment Length.

Measurement Details

Chest: Lay the garment flat and measure straight across from armpit to armpit. Multiply by 2 to get the full chest circumference.

Shoulder Width: Measure from the edge of one shoulder seam to the other across the back of the garment.

Sleeve Length: Measure from the shoulder seam to the end of the sleeve cuff.

Garment Length: Measure from the highest point of the shoulder next to the collar straight down to the bottom hem.

Important Notes

All measurements on our website are taken directly from the garment itself, not from body measurements. All garments are measured while laid flat. Due to manual measurement there may be a 1–2 cm variation between pieces. For the most accurate result we recommend measuring a similar garment you already own and comparing it with our size chart.

Helpful Fit Tips

If your measurements fall between two sizes, choose according to your preferred fit. If you prefer a little extra room, size up. If you prefer a more fitted, true-to-body silhouette, choose the size closest to your measurements. Our women's-fit tees are designed to sit close without feeling tight — when in doubt, check the chart against a tee you already love the fit of.
