Product Insights
The Openwork Details Wireless Bra by Wacoal offers moderate support with a natural shape and breathable knit that wicks moisture for all-day comfort, though it provides less lift than underwire styles. Its silky 86% nylon/14% spandex fabric and microfibre lining prevent irritation and minimize lace show-through, while the openwork lace lies smoothly under most clothing, sometimes showing slight texture under thin tops. Priced at $92 CAD—$35 above basic alternatives—the bra's exclusive design justifies the premium over support features. Care requires hand-washing in cold water without fabric softener and drying flat to maintain stretch and prevent pilling. Sizing runs true to band and cup, but sizing up may enhance lift. Adjustable thin straps and a two-hook closure offer fit flexibility but are not convertible to racerback.
Verified claims
- Breathability
- Breathable knit allows airflow and wicks moisture, preventing heat buildup.
- Durability
- Resists pilling, snagging, and maintains stretch when fabric softener is avoided.
- Support
- Moderate support with natural shape; less lift than underwire.
- Comparisons
- At $92 CAD, same price as Perfect Primer, lighter than How Perfect; design details, not support, justify premium above basic styles.
- Care
- Hand-wash in cold water, avoid fabric softener, dry flat to preserve support.
- Sizing
- Sizing runs true to band; cup consistent; consider sizing up for lift.
- Fabric
- 86% nylon/14% spandex feels silky; lining reduces lace show-through.
- Washing
- Wash in ≤30°C water, no fabric softener.
- Drying and storage
- Reshape and air-dry flat; store flat.
- Comfort
- Microfibre lining prevents lace-on-skin irritation and the knit promotes breathability for all-day comfort.
- Visibility
- Openwork lace lies smoothly under most clothing; thin or fitted tops may show slight texture.
- Price positioning
- The $92 price is $35 above alternatives, reflecting exclusive design rather than superior support.
- Strap and closure
- Adjustable thin straps with two-hook back closure; not convertible to racerback.
