Bra Fit Questions — Answered Simply
A calm, curated guide designed to help you feel informed, supported, and confident in your fit.
Finding Your Size
How do I measure my bra size at home accurately?
You can measure your bra size at home using a soft tape measure and two simple steps: measure your band and your bust while standing naturally and breathing normally. Keep the tape level and gently snug for the most realistic results.

Should I measure with or without a bra on?
For the most accurate results, measure without a bra or while wearing a thin, non-padded style. Structured or padded bras can subtly reshape the bust and affect your measurements.
What if my breasts are different sizes?
Natural asymmetry is very common. Fit your bra to your larger side for full support, then adjust the strap or use a light insert on the smaller side if you prefer.
How often should I re‑measure my bra size?
Your body changes over time, and your bra size can shift with it. Re‑measuring every 6–12 months helps keep your fit aligned with your current shape.
Understanding Your Fit
How do I know if my bra actually fits correctly?
A well‑fitting bra should feel quietly supportive. The band stays level, the center front rests flat, and the cups hold your shape smoothly without gaps or overflow.
Why is there a gap between my breast and my bra cup?
A gap usually means the size or style isn’t aligned with your shape. The cup may be slightly too large, or the bra’s design may not match your natural contour.
How can I ensure my bra fits properly?
The band should stay in place, the cups should sit smoothly, and the center front should lie flat. If the band lifts when you raise your arms, it may be too loose
The Calculator & Sizing Logic
How is this calculator different from others?
Most calculators rely on simple formulas. This one considers how bras are constructed, how fabrics behave, and how different tissue types respond to support — giving you a size that reflects how a bra is likely to feel.
What if I don’t know my tissue type?
If you’re unsure, select “Not Sure.” The calculator will give you a balanced recommendation based on common fit patterns.
What are sister sizes and how do they work?
Sister sizes share the same cup volume but adjust the band. If the band feels too tight, go up a band and down a cup; if it feels too loose, go down a band and up a cup.

Why is my size different in different brands?
Bra sizing isn’t fully standardized. Differences in materials, construction, and design can all affect how a bra fits, even in the same size.
Care & Longevity
How often should I replace my bra?
Most bras last around 6–12 months, depending on how often you wear them. If you’re adjusting more, feeling less supported, or the fit feels “off,” it may be time for a replacement.

How often should I wash my bras?
Everyday bras can be washed every 2–3 wears, while sports bras should be washed after each workout. Gentle washing and air‑drying help protect the elastic and extend their lifespan.
