What is 38C Bra Size? 38C Measurements in Inches & cm, Sister Sizes and Fit

A 38C bra size means a 38 band (your underbust measures about 33 to 34 inches) and a C cup (your bust measures about 41 inches, 3 inches more than the band). In centimetres that is an underbust of 84 to 86 cm and a bust of about 104 cm. 38C is a common fuller-figure size, the sister size of 36D, and the size where plus-size ranges begin on most Indian sites. Lovable India sells 38C in every style from non-padded cotton to t-shirt, padded and sports bras: see all 38C bras.

38C bra size measurements

Measurement	Inches	Centimetres
Underbust (band 38)	33–34	84–86
Bust (cup C)	41	104
Bust minus band	3	8

The band number is not your bust; it is your underbust plus 4 (even) or 5 (odd) inches, which is how Indian and international brands size bras. The cup letter is the difference between bust and band: A is 1 inch, B is 2, C is 3, D is 4, E is 5.

How to check if you are a 38C

Wrap a soft tape snugly under your bust and note the inches. 33 or 34 inches points to band 38.
Wrap the tape loosely around the fullest part of your bust. About 41 inches with a 38 band points to a C cup.
Try the bra: the band should sit level across your back on the loosest hook, the centre panel should touch your breastbone, and the cup should be full with no gap and no spill.

If the numbers do not match this exactly, use the full bra size chart or the bra size calculator.

38C sister sizes

Sister sizes hold the same cup volume on a different band. If a 38C band feels tight, try 40B; if it rides up and feels loose, try 36D. The cup letter changes but the cup itself stays the same size.

If 38C…	Try	Why
band is loose, cup fits	36D	tighter band, same cup volume
band is tight, cup fits	40B	looser band, same cup volume
cup spills over	38D	same band, one cup larger
cup gaps or wrinkles	38B	same band, one cup smaller

38C compared with nearby sizes

38C vs 38B: same band; 38C has a cup one inch larger (bust 41 vs 40 inches).
38C vs 38D: same band; 38D has a cup one inch larger (bust 42 inches).
38C vs 40C: same cup letter, but 40C has a 2-inch longer band and a slightly larger cup, because cup volume grows with band size. 40B is the true equivalent of 38C, not 40C.
38C vs 36C: same cup letter on a 2-inch shorter band; the 36C cup is slightly smaller.

Best bra styles for 38C

C cups benefit from a little structure. Full-coverage and 3/4th-coverage bras with wider straps hold the shape; wired styles give lift under sarees and dresses; non-wired full-coverage styles are better for 10-hour days; padded t-shirt bras work well but choose thin padding, not push-up. Browse by style: t-shirt bras, padded bras, non-padded bras, seamless bras, sports bras and full coverage bras, then filter to 38C.

38C bra FAQs

Is 38C a small, medium or large bra size?

38C is a full size: a wider ribcage with a fuller cup, the same cup volume as 36D. The cup letter alone does not tell you the volume: a C cup on a 38 band is a different size from a C cup on a 42 band.

What is 38C bra size in cm?

Underbust 84 to 86 cm and bust about 104 cm. European sizing calls this 85C.

What is the difference between 38C and 40C?

The band. 40C is for an underbust of 35 to 36 inches, 38C for 33 to 34 inches. Because cup volume scales with the band, the 40C cup is also a little larger than the 38C cup.

My 38C band rides up at the back. What should I do?

The band is too loose. Try 36D (tighter band, same cup) or tighten to the inner hook. A band that rides up gives no support no matter how the straps are set.

Which 38C bra is best for daily use?

A non-padded or lightly padded, non-wired, full-coverage cotton bra. See 38C bras on Lovable India from ₹179.

Does 38C change after weight gain or loss?

Usually by one band size for every 5 to 7 kg, and sometimes a cup. Re-measure every six months and after any change in weight, pregnancy or exercise.
