Does The Flat Head run true to size?

Going by the published charts, The Flat Head runs small. For a 32″ waist we’d pick a tag 33 in 3 of 8 models, a size up from your waist. That aims for a waistband at your waist after the first soak: selvedge gives about an inch with wear.

Your waist	Tag we’d pick	In
30″ (76 cm)	31	3 of 7 models
32″ (81 cm)	33	3 of 8 models
34″ (86 cm)	36	4 of 8 models
36″ (91 cm)	36	4 of 8 models
