Fit callouts worth noting
Bands fit close to measured size
Most New Look bands align with tape measurements, offering a moderate hug without sharp stretch.
Try this:
Begin with your measured band; add the neighbor size if you fluctuate or prefer more or less tension.
Cups lean shallow or push-up heavy
Padding placement and low gores at New Look 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.
Check necklines on molded T-shirt bras
Different New Look T-shirt cuts shift strap width and neckline height, changing how the foam sits on your bust.
Try this:
Compare plunge vs. full coverage molds to see which anchors at the gore without gaping.
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 New Look sizing.
- Note the style you are targeting (plunge, balconette, wireless) so you can sanity-check the fit advice below.
Check band tension once clasped
- Start with your measured band and assess comfort on the loosest hook.
- If you fluctuate between sizes, add the adjacent sister size so you can fine-tune stretch vs. security.
- Use easy return windows to compare band tension across at least two sizes before committing.
Compare coverage levels in molded cups
- Try both plunge and full-coverage molds to see which neckline lays flat.
- Check for gaping near the gore; molded cups should tack without floating.
- If straps sit wide, swap to a plunge or racerback clip to keep cups anchored.
