Fit callouts worth noting
Bands relax quickly with wear
Sloggi often uses soft elastics that ease up after a few wears, especially in wireless or lounge styles.
Try this:
Order your regular band and the sister size down so you can choose the secure feel you prefer.
Cups lean shallow or push-up heavy
Padding placement and low gores at Sloggi can crowd fuller-on-top tissue, causing spill at the edge.
Try this:
Sister size up in the cup or choose balconette/demi styles with taller upper cups to trim spillover.
Wireless styles trade structure for comfort
Wireless and bralette silhouettes at Sloggi rely on stretch bands that can roll or ride if the band is loose.
Try this:
Test both your usual band and the smaller sister size to see which stays anchored during movement.
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 Sloggi sizing.
- Note the style you are targeting (plunge, balconette, wireless) so you can sanity-check the fit advice below.
Plan for stretch-friendly bands
- Order your usual band alongside the sister size down to see which feels secure after break-in.
- If you prefer lounge-level comfort, keep the stretchier option for home wear and reserve the firmer one for outings.
- Use easy return windows to compare band tension across at least two sizes before committing.
Test wireless support in motion
- Do a stretch test; bands should stay level even without wires.
- Layer a thin tee to check for shape you like before deciding.
- Rotate bras to let elastic recover between wears.
