How to Pick the Right Wacoal Size
- Measure your under-bust and bust at home (snug under, loose over).
- Wacoal runs true to size — buy your measured size on the loosest hook.
- Try the bra on the loosest hook for the first 2–3 weeks of wear.
- Test the fit using the band test (two fingers under) and cup test (no spillage, no gap).

Common Wacoal Fit Issues
- Band stretching out faster than expected — replace at 6 months in heavy rotation.
- Cup gapping at top — sister-size down or try a different cup style.
- Underwire too narrow — switch to a brand designed for projected breast shapes (Freya, Chantelle).
