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

Our review of the PLAYTEX Womens 18 Hour Side & Back Smoothing Wireless Bra finds it best for anyone who wants reliable everyday support without an underwire and a smooth silhouette under tees. The single biggest reason to buy is its targeted side and back smoothing combined with the TruSUPPORT 4-way system, which keeps the shape and reduces bulge while remaining comfortable for long wear. The cooling, moisture-wicking cup fabric also helps maintain comfort through a busy day, making this a practical choice for daily wear.

Key Features

• Side and back smoothing: Extra fabric and structure at the sides and back reduce visible lines and create a sleeker profile under fitted shirts.
• Moisture-wicking cups: Cooling fabric in the cups pulls moisture away from the skin to help keep the bust feeling dry during warm or active days.
• Wire-free comfort: Non-foam, wire-free cups offer support without the pressure of underwire for extended all-day wear.
• No-slip adjustable straps: Cushioned Comfort Straps are designed to stay put and relieve shoulder pressure when adjusted correctly.
• Sleek cups: Smooth, seamless cups disappear under clingy tops for a clean t-shirt look without added bulk.
• TruSUPPORT system: Integrated support from cups to straps gives an all-over sense of lift and containment without wires.

Who It's For

This bra suits women who prioritize comfort and a smooth appearance under everyday clothing, especially those who dislike underwires but still want noticeable side and back support. It is a good match for anyone who needs a reliable bra for workdays, errands, or travel where long-wear comfort and a t-shirt-ready finish matter.

Shoppers seeking very soft, plush fabric or precise specialty sizing may want to try alternatives first, since customer feedback on material softness and fit is mixed and some buyers report sizing runs small. Those who need heavy lift or shaping may prefer a wired or molded-option bra instead.
