Bra Size Guide

Find Your Perfect Fit

Choosing the right bra size is not about numbers alone — it is about comfort, support, and how your body feels throughout the day.

This guide will help you measure correctly and understand how bra sizing works.

Step 1 — Measure Your Bust (Overbust)

Wrap a soft measuring tape around the fullest part of your breasts.

✔ Keep the tape level across your back
✔ Do not pull too tight
✔ Stand naturally (do not lift your chest)
✔ Wear a thin, non-padded bra for accuracy

This measurement is your Bust Size.

Step 2 — Measure Your Underbust (Band Size)

Wrap the measuring tape firmly around your ribcage, directly under your bust.

✔ Keep the tape parallel to the ground
✔ Pull snug but not tight
✔ Breathe normally

This measurement is your Underbust Size.

Step 3 — Calculate Your Cup Size

Your cup size is determined by the difference between:

Bust Measurement – Underbust Measurement

Example

Bust: 90 cm
Underbust: 75 cm
Difference: 15 cm

15 cm difference = C Cup

Sizing may vary slightly by brand.

Step 4 — Determine Your Band Size

Use your underbust measurement to determine band size.

Example Size Calculation

Bust: 90 cm
Underbust: 75 cm

Band: 34
Cup: C

Final Size: 34C

How Should a Bra Fit?

A properly fitted bra should:

✔ Sit level across your back
✔ Feel supportive without digging
✔ Have cups that fully contain your breast tissue
✔ Stay in place when you raise your arms
✔ Not cause red marks or discomfort

When Should You Re-Measure?

Your bra size may change due to:

• Hormonal changes
• Weight fluctuation
• Pregnancy
• Postpartum recovery
• Aging
• Changes in exercise routine

We recommend re-measuring every 6–12 months.

Fit Philosophy

At icmarts, we believe bra sizing is not about shaping the body into a fixed standard —
it is about understanding how your body changes and choosing support that adapts with you.

Comfort is not optional. It is foundational.
