Smooth T-Shirt Bras Built to Disappear Under Clothes
Wacoal's Baseline Collection is designed to make everyday dressing effortless. Silky-smooth fabric and seamless stretch foam cups create a clean, streamlined look under T-shirts, knits, and fitted tops, while light padding provides opacity and gentle shaping.
Both styles offer mid coverage, fully adjustable straps, and encased back elastic for a comfortable, customized fit. With sizes from 30-38 bands and A-DDD cups, the Baseline Collection offers a versatile range of fit options, including smaller band and cup sizes.
Because the cup holds its shape rather than relying on a full fill, Baseline works for breast shapes that are often difficult to fit. Wacoal recommends both styles for round, shallow top and full bottom, and petite shapes, and recommends the wire free style for east west shapes as well.
The Baseline Collection Includes:
Baseline T-Shirt Bra
For added structure, this seamless underwire style uses soft stretch foam cups to create a natural round shape while keeping the finish smooth under clothes. Shop the Baseline T-Shirt Bra.
Baseline Wire Free T-Shirt Bra
Prefer no wire? Built-in under-bust panels and flexible side boning provide support and shaping while maintaining the same silky, seamless feel. Shop the Baseline Wire Free T-Shirt Bra.
From everyday T-shirts to fitted tops, Baseline is made to be the bra you reach for on repeat.
