FAQ

Which size for Björn Borg boxers?

Use Björn Borg’s size chart based on waist measurement. Between sizes? Choose the larger for comfort.

Which bra sizes are equivalent?

Sister sizes shift band up/down and adjust the cup (e.g., 34C ≈ 36B ≈ 32D). Fit still varies by brand.

When is a bra too big?

If the center gore lifts, the band rides up, cups wrinkle, or tissue spills when moving. Try a smaller band/cup or different style.

Which bra size to buy?

Measure underbust and bust; calculate band and cup using the brand chart. Try multiple styles; the right size feels secure without digging or gaping.

How do Muchachomalo boxers fit?

Generally true to size with firm band and stretch. Check the size chart; between sizes, go larger for comfort.

Sister size of 80C?

75D (tighter band) or 85B (looser band) have similar cup volume. Always try on—brands vary.

Is 80E the same as 75F?

Nearly—similar cup volume (sister sizes) but different band. Always try on for comfort.

Do I have cup B or C?

Measure bust and underbust and consult a chart. When unsure, try both; cups should lie smooth without gaping/spillage.

How to calculate the right bra size?

Measure snug underbust and around the fullest part. Combine band and cup difference via brand chart—then try on.

Is 80C the same as 75D?

Yes—similar cup volume (sister sizes) with a different band. Trying on is key.

Is 80D the same as 75E?

Yes—similar cup volume with a different band. Comfort depends on fit.

What size strapless bra should I choose?

Usually your regular size, though strapless can be slightly firmer in the band. Keep the cup the same and test: band stays up and center gore lies flat.

What’s my Triumph bra size?

Triumph uses EU sizing (e.g., 75C). Measure underbust and full bust, then use Triumph’s size chart to confirm your size and model‑specific differences.

How do you know if a bra fits?

Band sits level and snug, center gore lies flat, wires encase tissue, no spillage or gaping, straps don’t dig. Two‑finger test under the band and move without shifting.

What size is equivalent to 95D?

Sister sizes: 90E (tighter band, larger cup) and 100C (looser band, smaller cup). Brands vary—always try on.

How big is a D cup?

“D” is cup volume relative to the band. A 70D looks smaller than a 90D. Consider band and cup together, not the letter alone.

What does the letter on a bra mean?

It’s the cup size—breast volume relative to the band (the number). A larger letter means more cup volume within the same band size.

What does 75 mean on a bra?

“75” is the EU band size—your underbust measurement rounded. The band provides most support, so it should fit snug and stable.

What size is equivalent to 75A?

Sister sizes: 70B (tighter band, larger cup). 80AA/80A depends on brand and is rare. Practical alternative: 70B or 80AA if available.

What size is equivalent to 90C?

Sister sizes: 85D (tighter band, larger cup) and 95B (looser band, smaller cup). Use as a guide and try different brands.

Is 90C the same as 85D?

They have similar cup volume (sister sizes), but 85D has a tighter band. If 90C fits in the cup yet the band slips, try 85D; otherwise 95B.

Is a C cup large?

C is mid‑range, but size is relative to the band: 70C looks smaller than 85C. Consider the number‑letter combination.

What size is the same as 90D?

Sister sizes: 85E (tighter band, larger cup) and 95C (looser band, smaller cup). Always try on—brands differ.

Is a D cup large?

D is often seen as large, but context matters: 70D looks compact, 90D much fuller. Band size shapes perception.

Which is bigger, D or DD?

DD (or EU size E) is one cup size larger than D within the same band. Note: labeling varies by country/brand.
