ザ・フラッシュ・マッスルチェスト - 大人用コスチューム

The muscle chest padding really sells the superhero look — my arms filled out the sleeves perfectly. Fit true to size for me in Large, and the fabric has enough stretch to move around comfortably.

The sizing runs a bit snug, so I'd suggest going up a size if you're between measurements, but the muscle chest padding gives a surprisingly convincing superhero silhouette.

The muscle chest padding adds just the right amount of bulk, and the fabric is comfortable enough to wear all night. I got the large and it fits true to size, which was a relief for a costume.
