How an Aloha Shirt Should Fit: Four Measurements That Matter
An aloha shirt should have ease, but relaxed is not the same as shapeless. Compare garment measurements with a shirt you already like before trusting Small, Medium or Large.

Start with the shirt, not your body
Lay a comfortable woven shirt flat and button it without stretching. Measure pit to pit, shoulder seam to shoulder seam, back length from the collar seam, and sleeve opening. Double the pit-to-pit number for an approximate garment chest circumference.
This becomes your reference garment. Compare it with the seller’s finished-garment chart, not a generic body chart. Two brands can assign the same size letter to very different shirts, and vintage sizing often runs on its own scale.
Read the shoulders and chest together
The shoulder seam can sit near the edge of the shoulder or slightly beyond it for a relaxed cut. If it falls far down the upper arm, the shirt may look intentionally oversized; if it pulls inward, the chest and upper back are likely under strain.
Button pulling, diagonal wrinkles from the armpit, and a placket that bows open indicate too little room. A clean front with enough space to reach forward indicates useful ease. The correct amount depends on the fabric: fluid rayon can tolerate more volume than crisp cotton without appearing boxy.
Length decides whether untucked works
A straight-hem aloha shirt is normally designed to work untucked. The hem should cover the waistband through ordinary movement without extending so low that it resembles a tunic. Your torso length matters more than a universal rule.
Check side and back views, then raise your arms and sit down. A shirt that looks right only while standing still is not the right length for daily use.
