I tried several different t-shirts, and was still struggling to find a brand that was long enough. Although I checked JCPenny's a few times, it seemed they never had large, tall, in v-neck. So I never got to try the Stafford.
Finally last week I tried Croft & Barrow at Kohl's and I hit the jackpot!!!!
Here I am in Hanes large which is packaged as "generous length":

Here I am in the Croft & Barrow large packaged as "long length ensures the shirt stays tucked in":

Pretty significant difference! Pack of 6 for $34.00 but usually on sale for less. I will picking up more very soon.
So if you know any lanky fellers ... I can whole-hardily recommend these shirts!
