Playtex Women's 18 Hour Side & Back Smoothing Cooling Wireless T-Shirt

Our review of the Playtex Women's 18 Hour Side & Back Smoothing Cooling Wireless T-Shirt Bra finds it best for anyone seeking a comfortable, everyday wireless bra that smooths the sides and back while staying cool all day. The single strongest reason to buy is its combination of targeted smoothing and non-wired support: the TruSUPPORT system addresses cups, sides, back and straps so the bra sits smoothly under tees and clingy tops without the pressure of underwire. Expect a classic hook-and-eye fit, moisture-wicking cup fabric, and cushioned adjustable straps for daylong wear.

Key Features

• Smoothing side and back: Extra fabric panels at the sides and back create a smoother silhouette under fitted shirts and dresses for a neater profile.
• Cooling cup fabric: Moisture-wicking material in the cups helps pull sweat away from skin to keep you feeling cooler and drier through the day.
• Wirefree comfort: Non-foam, wireless cups provide support without underwire pressure while remaining comfortable for long periods.
• No-slip straps: Cushioned adjustable Comfort Straps relieve shoulder pressure and are designed to stay in place during normal activity.
• 4-way TruSUPPORT system: Support is distributed from the cups to the sides, back and straps to improve overall fit and hold.
• Sleek cup finish: Smooth, low-profile cups disappear under t-shirts and other clingy tops for a clean look.

Who It's For

This bra is aimed at women who prioritize everyday comfort and a smooth appearance under fitted clothing, especially those who dislike underwire but still want structured support and side/back shaping. It works well for office wear, casual days, and layered looks where a seamless cup and tidy back are important.

Shoppers who need very precise cup sizing or prefer plush, foam-molded cups may want to try alternatives, since customers report mixed experiences with cup sizing and the fabric hand can feel different person to person. Those wanting a heavily padded or push-up effect should look elsewhere.

Pros & Cons

Pros

• Comfortable wirefree design that reduces shoulder and rib pressure compared with wired bras.
• Effective smoothing for sides and back that improves the look of fitted tops.
• Moisture-wicking cups help maintain comfort during warm days or extended wear.
• Cushioned adjustable straps stay put and reduce shoulder discomfort.

Cons

• Cup sizing has mixed feedback; some users find the cups run small while others find them large, so fit may need a careful try-on.
• Fabric hand varies in reviews, with a few users noting a rougher feel compared with softer bras.
