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

In this review of the PLAYTEX Womens 18 Hour Side & Back Smoothing Wireless Bra the bottom line is simple: it is a practical everyday t-shirt bra for anyone who wants extra side and back smoothing without underwire. The reviewer found it most valuable for long days when comfort and discreet shaping matter, because the TruSUPPORT design delivers stable, all-around support while the moisture-wicking cup fabric helps keep skin feeling cooler. This bra balances support, a smooth silhouette, and cushioned straps in a way that suits daily wear rather than specialty or high-impact use.

Key Features

• Smoothing side and back: Provides targeted smoothing where many t-shirt bras leave bulges, improving how tops lie across the torso.
• Cooling cup fabric: Moisture-wicking material in the cups helps reduce sweat buildup and keeps the wearer feeling fresher over long shifts.
• Wirefree comfort: Non-foam, wire-free cups offer support without the pressure or poking of underwires for all-day ease.
• No-slip straps: Adjustable Comfort Straps are cushioned to relieve shoulder pressure and designed to stay put during routine movement.
• Seamless look: Sleek, smooth cups disappear under clingy tops so tees and fitted shirts have a clean finish.
• TruSUPPORT system: Built-in 4-way support ties the cups, sides, back, and straps together for more consistent shaping.

Who It's For

This bra is best for women seeking a dependable, everyday smoothing bra that emphasizes comfort over dramatic lift. The wireless construction and cushioned straps suit those who dislike underwires or need a gentler feel at the shoulders while still wanting side and back support.

It is less appropriate for people who need highly adjustable technical support for high-impact exercise or who prefer very soft, stretchy fabrics; some reviewers noted the material can feel slightly firmer. Also, shoppers who require exacting precision in sizing should compare fit notes carefully, as sizing feedback has been mixed.
