Let me tell you, as someone who's tried countless training bras for my pre-teen, this Calvin Klein bralette is a game-changer. The seamless design really does disappear under clothes - no more awkward lines showing through school uniforms!

The fabric blend feels like a second skin. My daughter (who's petite at 100lbs) says it's the most comfortable bra she's ever worn. The built-in pad provides just enough coverage without being bulky, perfect for girls transitioning from sports bras.

Watch out for sizing though - while many reviewers found it true to size, the band runs a bit small. We initially ordered 36A which fit perfectly, but I noticed some confusion in reviews about the sizing labels. The pullover design (no clasps) makes it super easy for kids to handle independently.

After multiple washes, the quality holds up impressively - no pilling or stretching out. The iconic CK logo adds a cool factor that makes teens actually want to wear it. Just wish they offered more color options in the smaller sizes!
