I agree with ZE and OutLander. I've seen some window displays at local stores, as well as one unit I saw being unboxed at another store, and the stitch on the left sleeve varied from okay (since it's never as perfect as the machine-sewn parts of the suit) to bad.
I'm fine with mine Wasn't happy with the stitch on the forehead though as it seemed it's not tightly closed, store gave me a replacement which looks better and has webbings on the neck more aligned with the webbings on the body's collar. Here's a picture where the left sleeve can clearly be seen (I'm yet to take pictures with the new head).
Love your BD ASM! You made a POS suit look amazing!
