What is 38 Bra Size? 38 Band Measurements, 38A to 38E Cup Sizes and Fit

A 38 bra size means a 38 band: your underbust measures about 33 to 34 inches (84 to 86 cm). On its own, "38" is not a complete bra size, because the cup letter decides how big the cup is. A 38A has a bust of about 39 inches and a 38E a bust of about 43 inches on the same band. Below is every 38 size with its measurements, how to find your cup, and sister sizes if the band does not feel right. Lovable India stocks 38 in every cup and style: see all 38 size bras.

38C	41	104	3 inches
38D	42	107	4 inches
38E	43	109	5 inches

Underbust for every row: 33 to 34 inches (84 to 86 cm). The band number is your underbust plus 4 (even number) or 5 (odd number), which is how bras are sized in India.

How to find your cup on a 38 band

Measure under your bust, snug, in inches. 33 or 34 means band 38.
Measure around the fullest part of your bust, loosely.
Subtract 38 from the bust measurement: 1 inch is 38A, 2 inches 38B, 3 inches 38C, 4 inches 38D, 5 inches 38E.

Example: underbust 33 inches and bust 40 inches is a 38B. Underbust 34 inches and bust 41 inches is a 38C. For the full method and sister sizes, use the bra size chart or the bra size calculator.

Which 38 sizes are most common in India?

38B and 38C are the most-sold 38 sizes on Lovable India, followed by 38D. 38A is common for slimmer frames and teenagers; 38E and above are usually bought in full-coverage and plus-size styles. 38 is where plus-size styles begin on most Indian sites; 38B, 38C and 38D are the common sizes, and full-coverage non-wired bras sell best.

38 sister sizes

If a 38 band is too tight, go up a band and down a cup: 38B becomes 40A, 38C becomes 40B, 38D becomes 40C. If a 38 band rides up and is loose, go down a band and up a cup: 38B becomes 36C, 38C becomes 36D. The cup volume stays the same in both directions.

38 vs 36 vs 40: what "38 size" actually tells you

People often search "38 size" meaning overall breast size, but the number is only the ribcage measurement. A 36D and a 38B have roughly the same cup volume on different bands; a 38B and a 40B have different cup volumes with the same letter. So two women who both wear "38" can look quite different, and a woman with a fuller bust on a small frame may be a 36D rather than a 38B. Measure both numbers rather than guessing from the band.

Best bra styles for 38 sizes

For 38A and 38B: t-shirt bras, lightly padded and push-up bras for shape, seamless bras under fitted tops. For 38C and 38D: full-coverage and 3/4th-coverage bras with wider straps; wired for lift, non-wired for all-day comfort. For 38E: full-coverage non-wired with side support and a 3-hook band. Browse t-shirt bras, padded bras, non-padded bras, sports bras and full coverage bras, then filter to your 38 size.

38 bra size FAQs

Is 38 a big bra size?

38 is a band measurement (underbust 33 to 34 inches), not a breast size. 38A is a small cup and 38E a large one on the same band. 38 is above the Indian average band of 34, so it counts as a fuller or plus size by ribcage, whatever the cup.

What is 38 bra size in cm?

Underbust 84 to 86 cm. Bust depends on the cup: 38A about 99 cm, 38B 102 cm, 38C 104 cm, 38D 107 cm. European sizing calls the 38 band a 85.

What is the difference between 38B and 38C?

One inch of cup. 38B is for a bust of about 40 inches, 38C for 41 inches, on the same 33 to 34 inch underbust.

What is the difference between 38 and 40 bra size?

Two inches of band. 40 is for an underbust of 35 to 36 inches, 38 for 33 to 34 inches. If your usual 38 is tight, try 40 with one cup letter lower.

Which 38 bra is best for daily use?

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

How do I know if I am a 38 or a 36?

Measure your underbust. 33 to 34 inches is 38; 31 to 32 inches is 36. If you are at 33 inches and between sizes, choose 36 with one cup larger for a snugger fit.
