Playtex Women's Wireless T-Shirt Bra, 18 Hour Plus-Size - Smooth

In this review of the Playtex Women's Wireless T-Shirt Bra (4803) the bottom line is simple: this is a comfortable, supportive wirefree bra that works especially well for everyday wear and anyone who wants smoothing under tees. The most compelling reason to buy is the brand's long-standing M-frame design combined with the 4-way TruSUPPORT system, which delivers natural shaping and higher sides for bulge control without the discomfort of underwires. Fit can run small for some, but for those who get the right size, the bra balances softness, structure and a near-seamless look under clingy knits.

Key Features

• M-frame design: Provides flexible internal support that shapes the bust without relying on a wire, helping maintain a natural silhouette all day.
• TruSUPPORT system: Higher sides and fuller cups give visible bulge control and a smoother profile under shirts.
• Cushioned comfort: Wide, cushioned straps and a plush under band reduce digging and rubbing for extended wear.
• Almost-seamless finish: Smooth, satiny cups and satin trim make the bra disappear under t-shirts and other clingy tops.
• Stretchy sides and back: 2-ply stretch panels adapt to movement and help the bra stay comfortable through a long day.

Who It's For

This bra is aimed at anyone seeking a full-coverage, wireless t-shirt bra that smooths and supports without underwires, particularly plus-size shoppers who want higher sides and fuller cups for better containment. It is a practical choice for everyday wear, commuting, light activity and office or casual wardrobes where a seamless look matters.

Shoppers who need precise sizing for a sculpted fit should be cautious: several customers reported that this style runs small, so try a fitting or consider sizing up. Those seeking heavy-impact sports support or molded push-up shaping should look at specialized sports bras or contour styles instead.
