Your Boba looks pretty good, K.S., but seeing this photo reminded me of how my figure looked as I was still trying to decide whether the Medicom or Sideshow parts looked best.
As much as I liked having the separate SSC sash and codpiece, it made the figure look too bulky around the waist, so I ultimately went back to using the Medicom one which molded the two parts together. I also had to trim about 3/4" off the utility belt to make it fit more tightly as well as remove the fuzzy Velcro patch and used fabric glue to attach it to the shortened end of the belt, as you can see here:
I also tried using parts of the SSC armor, but not only found the shade of green matched poorly with the Medicom parts, but the gauntlets didn't fit well onto the slim Truetype forearms. And, since the Sideshow back armor also didn't cover up the Velcro strip on the Medicom vest, that also meant pulling the rocket backpack from the Medicom back armor, taking the straps off the Sideshow back armor, cutting some small slits to accommodate the wider straps, and gluing the straps onto the Medicom armor in order to use the much nicer Sideshow rocket pack.
But the scariest step I took was deciding the Sideshow neck-wrap was too thick and made of material that didn't match the rest of Boba's outfit, so I made a collar by cutting the one from the Medicom jumpsuit, sewing it closed, and fitting that around the bbi neck. This was the real point of no-return for me.
In all honesty, if I'd known from the beginning how much time, money and effort it would take to get my Boba Fett to where it is, I don't know if I would have done it. However, I am pretty pleased with how it turned out and more than happy to help out any parties willing to do the same thing, just to save them some frustration and/or heartache.
