Choose the right fabric weight and structure for your intended fit, hand feel and collection positioning.
We develop oversized, boxy and relaxed T-shirt fits by balancing shoulder width, chest volume, body length, sleeve shape and fabric structure.
Dropped shoulders, increased chest width and fuller sleeves create a balanced oversized T-shirt fit with controlled body length and modern proportions.
A wider body, structured shoulders and controlled length create a boxy T-shirt fit with balanced sleeves, clean lines and compact proportions.
Balanced shoulders, moderate chest width and natural sleeves create a relaxed T-shirt fit with comfortable movement, controlled length and everyday versatility.
