How 28C is measured
Band fit
Aim for a 26.5–27.5 inch snug underbust so the 28 band provides secure support without feeling restrictive.
Cup depth
Expect around 29.5–31.5 inches at the fullest point—roughly 3 inches beyond the snug band measurement.
Support focus
Look for reinforced bands, side support panels, and 3–4 hook closures to stabilize the cup volume.
28C bust size in inches
| Measurement | Typical inches | How to capture it |
|---|---|---|
| Snug band (ribcage) | 26.5–27.5 in | Measure firmly under the bust on an exhale, then round to the 28 band label. |
| Standing bust | 29.5–31.5 in | Keep the tape level across the fullest point while you stand tall and relax your shoulders. |
| Approx. cup depth | 7.5–8.5 in | Measure from the underwire to the apex on a well-fitting bra—confirms the depth needed for full projection. |
| Band-to-bust difference | ≈3 in | Subtract your snug band from the standing bust to verify the classic C-cup gap. |
28C bust size in centimeters
| Measurement | Typical cm | How to capture it |
|---|---|---|
| Snug band (ribcage) | 67–70 cm | Measure firmly under the bust, let the tape rebound slightly, then match to EU/JP band (US/UK 28). |
| Standing bust | 75–80 cm | Keep the tape level across the fullest point while standing naturally; avoid compressing tissue. |
| Approx. cup depth | 19–22 cm | Run the tape from underwire root to apex on a supportive bra to ensure the cup height matches your projection. |
| Band-to-bust difference | ≈8 cm | Subtract the snug band from the standing bust to confirm the C-cup depth in metric sizing. |
- Leaning bust readings help verify there is enough tissue to fill the upper cup completely.
- If the band feels loose, try the 26D sister size for a tighter anchor.
- Hormonal swelling can nudge you toward 28B/28D—recheck measurements during cycle peaks.
- Need the metric view? 28C typically lands around 67–70 cm underbust and 75–80 cm bust—use it for EU/JP conversions.

How 28C tends to look
Wondering what a 28C bra looks like? Expect proportioned curves on smaller frames with noticeable waist definition.
- Under fitted clothing it creates a rounded, defined silhouette with clear waist-to-bust contrast.
- On shorter torsos the volume can appear more dramatic; taller frames distribute it more evenly across the body.
- Balconette and plunge styles emphasize the curves while providing excellent lift and support.
- Properly fitted bras with side panels help manage the projection and prevent east-west spreading.
28C compared with nearby sizes
Use these quick comparisons to understand 28C relative to its equivalent sizes and neighboring cups.
- 28C vs 28B: the 28B cup is one level shallower, so it suits slightly less projection.
- 28C vs 30B: 30B keeps the cup depth but relaxes the band by one step—ideal if you need more room.
- 28C equivalent size: EU 60C / FR 75C / JP 60C. Drop to 26D or up to 30B when you need to adjust the band.
Sister size playbook
- Shift to 26D when you need a firmer band and closer support around the ribcage.
- Move to 30B if the 28 band feels restrictive or you're between hook settings.
- Try 28B when you need just a touch less cup depth while keeping the same band size.
Fit checks before you buy
When trying on 28C bras, look for these key fit indicators:
- The band should fit snugly around your ribcage
- Cups should fully contain your breasts without spillage
- Straps should stay in place without digging in
- The center gore should lie flat against your chest
- Ensure the center gore rests flat against your sternum—floating indicates you need more cup depth.
- Look for bras with side support panels or three-part cups to keep tissue centered.
- Choose styles with 3–4 hook closures for better weight distribution and longer-lasting support.
- Adjust straps for lift but ensure the band carries most of the weight, not your shoulders.
Remember that fit can vary between brands and styles. Always try on bras before purchasing to ensure the perfect fit.
