The Germany international is particularly impressed with the new collar on the defeated Champions League finalists' home and away strips for the 2013-14 campaign
The strips for the 2013-14 season were unveiled on Friday at a lavish ceremony at Westfalenpark, the centrepiece of which was a floral representation of the home jersey that covered 1000 square meters and 80,645 flowers.
Reus, though, was more impressed with the real thing, telling reporters: "The design and fit of our new jersey are really fantastic. They have fully met my expectations, especially with the new shape of the collar.
"What I hope is that with this new shirt we will have a richly successful season."
Dortmund was beaten by Bayern Munich in last season's Champions League final and finished well behind its Bavarian rival points-wise in the Bundesliga, despite ending in second place.
