The innerwear will improve your posture and give you a completely different impression.

Simply wear it under your outerwear and you'll naturally become aware of good posture and feel like your back is straight! The secret is the soft power net placed on the skin side above your shoulder blades. It feels like it's gently pushing against your back, and the comfort of the garment will let you know about your bad posture. It's also comfortable against your skin, so wear it often to make good posture a habit.

For those concerned about their posture

I bought this because I'm concerned about my posture and wanted to improve it even a little. The texture is also nice.

I wear this under a short-sleeved polo shirt when I'm working out. It feels nice against the skin, and I'm glad I bought it. When putting it on, you have to be careful to make sure the mesh is on your back.
