After a 38 band size, the band size should be the closest higher even number to your actual measurement.
S0, 41.5" is a 42 band. A 41" measurement is a 42 band.
Keeping the measuring tape parallel with the ground, measure around your bra directly under your bust after expelling all air from your lungs - you want this measurement to be as small as possible. Round all fractional measurements to the nearest whole number.

Measure for
Cup Size
Standing straight, with your arms at your side, measure at the fullest part of your bust (while wearing a non-padded bra) making sure the measuring tape is parallel with the ground and not binding. Round all fractional measurements to the nearest whole number.
Calculate for
Bra Size
Subtract your band measurement (step 1) from your cup measurement (step 2). Generally, for each inch in difference, the cup goes up by one size. For example:
Step 1
34" under measurement = 36" band
Step 2
38" over measurement
Step 3
38" - 36" or Cup "B"
Your size would be 36B
The cup size calculation starts falling apart at 4 inches larger than your band size, and if you have droopy pendulous breasts, your measurement will not be accurate. See the cup size conversion chart below.

*Cup sizes larger than a D are called different letters by different brands (a DDD cup size in one brand can be called an E or F in other brands). So know your Universal Cup Size and you can find your correct size in any brand at HerRoom. Learn How To Find Your Universal Cup Size
This measuring system tends to become less accurate as the cup sizes go above a D. Additionally, some manufacturers name larger cup sizes differently.
