Thanks,
Doesn’t need to be screen accurate but something good that I can always upgrade and improve over time I guess.
Unfortunately, it's tough with a $1500 budget to get a super accurate costume for Boba Fett. It won't get you 501st approval obviously, but you can still make a decent Halloween costume with that budget in my opinion. With that being said, with a budget that strict I would invest the majority into the armor itself and buy everything else cheaper as you can always upgrade it later.
This is the parts list I would go with:
1. MinuteFett ESB Armor set (painted) - ~$1000 (Etsy)
2. Ebay/AliExpress boba fett costume - $150 (Specifically the one pictured below). Can be found from many vendors if you search "boba fett costume". You are only buying this for the decent flightsuit and flakvest. You could use the ammo belt and girth belt if needed as well.
I started with this costume before I really go into building my Fett. The costume by itself isn't good, but the flight suit and flakvest are very serviceable for the price, and I actually used them for quite a while until I finally purchased an upgraded one. All you need to do with the eBay costume is use a seam ripper to remove the leather armor pieces and then replace with MinuteFett's armor. Here is how mine looked early in the process using this flightsuit as a base:
3. Disney ESB Gauntlets - $40 (can be found on eBay or other sites)
4. Cheap "Chelsea Boots" off of amazon ~$30-40. Something like these but maybe with a thicker sole if you can find a pair:
This leaves you ~$250 to get odds and ends. You could use that to upgrade different parts mentioned above or put it towards a decent 3D printed Jetpack/gauntlets.
To attach the armor, buy ~50 count of clutchback pins on Amazon and some upgraded "pin keepers". Superglue the pins to the back of all of the armor pieces and attach to the flakvest.
I think that this would be a good base that you can slowly upgrade from, and will at least give you the "look" of Boba Fett in the meantime. In my opinion having good looking armor / helmet is the most important part if you are just looking to impress normal people that aren't obsessed with Boba Fett like we are on here!
