Welcome aboard! I'm honored to have inspired you! Selfishly that will also help my motivation to really get cracking on her, once again! She's certainly not an easy build, but I have never heard anyone say she's not worth it. I look forward to your progress!
I have a KB kit- I got a little caught in the mess they had, but I did in fact get my armor, and I'm happy with it. I have a friend and new fellow Squad mate who also has KB for his TLJ TK, he got in after the mishaps, and got his kit in a couple of weeks (insanity!). He's also done and approved already. So now he's going to help me instead of the other way around, hahaha!
@LadyInWhite is roughly local to you- So Cal at least (which I realize is large- I'm from the Central Valley CA).
I'm 5'11, so we're not too far of in height. KB should have no problems for you at your height. Jimmi makes a nice kit, but he is a smaller guy and I've noted his various kits reflect that (you build what you know- makes sense). His is also fiberglass v. KB is ABS, and I personally think ABS is easier to work with and I prefer it. Shawn Thorrson also does Phasma kits now, too! I know next to nothing about them other than his has a helmet and KB's doesn't. But I have his helmet.
As far as shoes go, if you want lifts (at your height, with any normal boot heel, plus a little added from the helmet dome, you don't need to if you don't want to), then I would recommend something with a lace up front- the laces will get covered by the (TFA) boot armor, and thus be CRL compliant, and they will also give your foot room to rise up with the lifts. I don't think the TLJ foot armor would completely cover, however, so that's really an option for TFA only. I'm not as well-versed on TLJ as I am on TFA, though. PayLess if going out of business, but that's where I snagged mine, for like $20.
I plan to use my TK undersuit, which is a black compression shirt and pants. They're pretty available in a lot of sizes- just do a google search and you should find some options (Eastbay tops I like, and I have a random brand pants I found on Amazon; I might switch to Men's because women's tend to be smaller fits). I'd recommend not the winter variety, as the suit will be hot enough as it is. Moisture wicking is a plus. (I actually need to replace a pair of my TK understuit paints, ended up with a hole right on the butt, which I found at a troop, but thankfully the armor covered it, so if I find a good option I'll drop you a line).
I just ordered Jessica's cape and belt this morning! So excited! She's doing a very small run of up to 5 right now, so if you're able, jump on that quickly (Facebook, Jessica Bowyer). If not, there are other options and she will do other runs in the future, too.
Not to totally plug my own stuff, but my ESB TK build will have some cross-cover as far as supplies, tools, etc. Harbor Freight clamps for the win! Love those things. I'd recommend investing in a real Dremel, not an off brand (or at least not the $30 ones from Amazon), as I've now burned out two of them over three years (though not a terrible run).
I'm doing pretty good on the basics, just don't ask me how to build her... still pretty such on that part!
