PLAYTEX Womens 18 Hour Side & Back Smoothing Wireless Bra (Style 4620)

In this review of the PLAYTEX Womens 18 Hour Side & Back Smoothing Wireless Bra the bottom line is simple: this bra is best for anyone who wants a smooth, wire-free tee bra with extra side and back support that stays comfortable all day. The single biggest reason to buy is the TruSUPPORT 4-way design that combines smoothing panels with cushioned, adjustable straps for reliable support without wires. It performs especially well under clingy tops where a sleek cup and moisture-wicking fabric help keep things neat and cool.

Key Features

• Side and back smoothing: Built-in panels provide extra coverage and help create a streamlined silhouette under clothes.
• Cooling cups: Moisture-wicking fabric in the cups reduces sweat and helps you feel fresher during long wear.
• Wirefree support: Non-foam, wire-free cups deliver support without an underwire digging in.
• No-slip straps: Cushioned Adjustable Comfort Straps are designed to stay put and ease shoulder pressure.
• Sleek appearance: Smooth, seamless cups disappear under t-shirts and other fitted tops for a clean look.
• Classic closure: Hook-and-eye back closure gives a familiar fit and makes it easy to adjust band tension.

Who It's For

The bra suits everyday wearers who prioritize comfort and a smooth profile under tees, blouses, and fitted knits; it is particularly useful for those who dislike underwires but still want side and back support. The cooling cup fabric and cushioned straps make it a practical pick for long days, commuting, or layered outfits where a sleek cup is needed.

People who need very precise sizing or prefer very soft, stretchy knit cups may want to try it on first, since customers report mixed feedback on how the material feels and some sizing variability. Those who require molded foam cups or structured push-up shaping should look elsewhere.

Pros & Cons

Pros

• Comfortable wireless construction that still provides tangible support through the TruSUPPORT system.
• Effective side and back smoothing that helps create a cleaner silhouette under clothing.
• Moisture-wicking cups keep the wearer cooler compared with standard cotton bras.

Cons

• Sizing has received mixed feedback so some may find the fit smaller than expected and should consider trying different sizes.
• Material feel is divisive: some find it soft while others describe it as slightly stiff compared with plush bras.
