I wear Diesel jeans at 29W, mostly Viker and Thanaz.
What size should I get for PRPS Barracuda?
29 would be safe. Just know that the waists on PRPS fit tight but the hips are wider as they kinda have that baggier look on their styles. I guess they did this for more fit guys with bigger thighs...Im not sure. I have GTO and I wear a 33 in them, but it depends on the wash just like in diesel. The wash of my GTOs stretched more. I wear a 34 in Thanaz and 33 in zathan.
