How to Tell If a Bra Fitsを正しく行うための詳細ガイドを解説します。

The band does about 80% of the support work, so treat it with respect. Slide two fingers under the band at your back—if it feels like a handshake, you’re golden. If you can pull it an inch away from your body, size down; if it cuts into your skin like a secret you can’t tell, size up.

Fun fact: A stretched-out band is the number one reason bras “fail,” not a broken strap. Think of it as the elastic equivalent of a bad Spotify playlist—it loses its rhythm over time. Check that the band stays parallel to the floor, not riding up like a curious cat.

The Underwire: No Poking, Please

Your underwire should lie flat against your ribcage, like a loyal friend who knows when to shut up. If it digs into your breast tissue or leaves a red trench line, that’s a hard pass. Imagine that wire as the plot twist in a Ryan Gosling movie—it should be subtle, not painful.

Here’s a quick test: Raise your arms above your head. If the bra shifts or the wire pops away, it’s not your soulmate. In the words of every fashion editor ever: “No boob should ever be mugged by metal.”
