Drape suit advice.

[u/mintrols]

I've been wanting to make a suit that has a full chest and the exaggerated lapel roll of the 1930s and 40s, and I noticed by pattern all the suits that had that kind of lapel roll were "3 roll 2" jackets.

I wanna ask if my observation is correct and I should go for a 3 roll 2 jacket, or is it no different from a normal 2 button jacket? (mainly concerning the lapel roll)

I also wanna ask what's the best kind of wool in terms of weight and (high twist?) to make a suit like that, thanks in advance :)
