Fit callouts worth noting
Bands run firm out of the box
PrimaDonna uses sturdy wings, shorter elastics, and supportive hardware that can feel tight until broken in.
Try this:
Start with your base size plus the sister size up in the band to compare tension before removing tags.
Cups run deep with forward projection
Multi-part cups at PrimaDonna pull tissue forward, leaving extra room for projected or pendulous shapes.
Try this:
If you are shallow or in-between, try the sister size down in the cup or explore demi cuts with more open top lines.
Lace overlays hide structured seaming
Even delicate PrimaDonna lace bras rely on seamed linings that change stretch and coverage.
Try this:
Read fabric composition and test the style seated and standing to confirm seams sit flat.
Try-on strategy playbook
Dial in your baseline size
- Run the ABTF calculator or your trusted measurement routine first so the converter starts from fresh numbers.
- Keep your most reliable bra size handy; the converter maps it directly into PrimaDonna sizing.
- Note the style you are targeting (plunge, balconette, wireless) so you can sanity-check the fit advice below.
Bracket tight bands before committing
- Order your baseline band plus the sister size up (e.g., 32F and 34E) to test firmness.
- Wear each bra on the loosest hook and inhale deeply; firm wings should stay level without pain.
- Use easy return windows to compare band tension across at least two sizes before committing.
Audit fabric stretch before committing
- Inspect inner mesh or lining; supportive layers should match your support expectations.
- Try the bra seated, standing, and reaching to confirm seams stay flat.
- Hand wash or use lingerie bags so lace retains its resilience.
