Kiki's Awesome Sprites

i notice that using lighter and more grey-toned colors create the effect of a softer edge, so you could try doing that for part of the tie to make it taper out more.

Alternatively, creating a colour that's a balance/average between to the two contrasting colours will create a "blending" effect, and to the common eye, a half-pixel line (as long as they're not looking at it zoomed up).

In this situation, it'd be finding the halfway point between the white & blue used. If you're no good at finding this colour intuitively, you can just create a copy of the tie itself, then place in the pixels on the side of the tie at 100-125 transparency, then paste 'em over the white shirt, and the program should create the blending effect itself. I think you have to use separate layers for that if you're not using dreammaker to make 'em, though, since the transparent paste would just overwrite the white shirt on most programs.
