It's not uncommon for people to mix up the Soldier and Engineer, even with the default loadout. The only problem with this item is it only increases the amount of confusion since the top is mostly solid color and it makes the engineer look more bulky. (the hat also resembles the shape of some Soldier hats) Honestly when I first saw pics of this set I wasn't sure class which it was for.

This is a great looking set, but it's just something to keep in mind. Unfortunately, I don't know how to make it look less like something the soldier would wear.
