📏 How to Measure Your Bra Size

Underbust: Measure around your ribcage directly under your bust. Keep the tape snug but comfortable.

Bust: Measure around the fullest part of your bust, keeping the tape parallel to the ground.

Stand Straight: For best results, measure while wearing a non-padded bra.

Be Accurate: Use a soft measuring tape and measure in front of a mirror if possible.

💡 Understanding Sister Sizes

Sister sizes are alternative bra sizes with the same cup volume but different band sizes. If your band feels too tight, try a sister size up. If it's too loose, try a size down.

Example: If you're a 34C, your sister sizes are 32D (smaller band) and 36B (larger band).

✨ Bra Fitting Tips

• The band should provide 80% of the support, not the straps

• Your breasts should fill the cups without spillage or gapping

• The center gore should lie flat against your sternum

• Straps shouldn't dig into your shoulders

• Always try bras on the loosest hook setting
