Quick answer

The Infinite T-Shirt Nursing Bra delivers a smooth, invisible silhouette under fitted tops. Follow these steps to find your size and get the best seamless fit.

Why seamless fit matters for nursing bras

A seamless nursing bra hides under thin fabrics and avoids visible lines that can distract from your outfit. The Infinite T-Shirt Nursing Bra uses smooth contour cups and a wireless underbust to lift and shape without adding bulk. This makes it ideal for everyday wear, especially under tees, blouses, or knit dresses.

Because it’s wireless, the bra relies on the contour cups and flexible side panels for support. If the band rides up or the cups gap, the seamless look breaks. Getting the fit right is key to both comfort and invisibility.

Step-by-step seamless fit guide

  1. 1. Measure your band snugly: Wrap a measuring tape directly under your bust, keeping it level and snug but not tight. Round up to the nearest even number. This is your band size. Common mistake: measuring too loose, which causes the band to ride up and create back bulges.
  2. 2. Determine your cup size by leaning forward: Lean forward and measure the fullest part of your bust, keeping the tape parallel. Subtract your band size from this number. Each inch difference equals one cup size (e.g., 1 inch = A, 2 = B, etc.). Common mistake: measuring while standing upright, which can underestimate cup volume.
  3. 3. Check the band level across your back: Put on the bra and fasten on the loosest hooks. The band should sit parallel to the floor, not riding up. You should be able to slide two fingers under the band. Common mistake: wearing the band too high, which shifts weight to the shoulders and causes straps to dig in. If the band rides up, go down a band size and up a cup size to maintain volume.
  4. 4. Verify cup fit with a T-shirt test: Wear a thin, fitted T-shirt or knit top. Look for any gaping at the top edge of the cup or puckering in the fabric. The contour cups should lie flat against your skin without pressing in. Common mistake: choosing a cup that is too large, which creates a baggy look under clothes.
  5. 5. Adjust straps for even tension: Straps should be snug enough to stay in place without digging in. They should not slide off your shoulders or leave red marks. Common mistake: overtightening straps to fix a loose band, which strains the shoulders and breaks the seamless line. If straps keep slipping, try a smaller band size or a different style with convertible straps.
