PLAYTEX Womens 18 Hour Side & Back Smoothing Wireless Bra (Style 45T4)

In this review the PLAYTEX Womens 18 Hour Side & Back Smoothing Wireless Bra is judged on comfort, fit and everyday wearability; it is best for someone who wants reliable smoothing and wirefree support for daily tees and workwear. The single biggest reason to buy is the TruSUPPORT 4-way design that combines extra side and back smoothing with cushioned straps and moisture-wicking cups, so it stays comfortable over long days without underwire pressure. Reviewers who prioritize a sleek silhouette under clingy tops will find this bra especially useful.

Key Features

• Side and back smoothing: Built-in panels provide extra coverage and a cleaner line under fitted shirts and dresses for a less bulky look.
• Moisture-wicking cups: The fabric in the cups helps pull sweat away from the skin so the bra feels cooler during long wear.
• Wirefree comfort: Non-foam, wirefree cups offer support without the discomfort of underwires for all-day use.
• No-slip straps: Adjustable Comfort Straps are cushioned to relieve shoulder pressure and are designed to stay in place throughout the day.
• Sleek cup shape: Smooth, low-profile cups disappear under t-shirts and clingy tops for a neat finish.
• TruSUPPORT system: Integrated support across cups, sides, back and straps for balanced lift and shaping.

Who It's For

This bra is a solid choice for anyone seeking a comfortable, wireless everyday bra that smooths the sides and back while remaining discrete under clothing. It works well for office wear, casual tees and layered outfits where a seamless look matters, and for wearers who dislike underwires but still want defined support.

Those who need very soft, stretchy fabric or who consistently find bras run large may want to try other styles first, since customer feedback on sizing is mixed and some people find the material firmer than expected. It is offered in single and 2-pack options making it convenient for wardrobe rotation.
