Okay, I just have to tell all of you… over the past few days I have read this ENTIRE thread! I’m a bit cross-eyed but completely in awe-- you all ROCK!!!
Here’s my deal… 28 years experience in the saddle, have always been “plush,” eventually got way too plush and had gastric bypass surgery a few years ago. I lost a bunch of weight and I’m down to what will hopefully be my “normal” weight from now on (about 200), which I am completely happy with, but it’s left me very strangely shaped, to say the least. From the waist down, I pretty much have a “skin suit,” haha… plastics would help, but a.) I’m too cheap, and b.) it would put me out of commission for too long to heal, so I’m sucking it up. 
Luckily, I can wear the upper end of normal-sized clothes now, except for my calves-- oh sweet jesus they are enormous, 18" if I’m standing, 19+" when sitting. That, coupled with the fact that I’m short (5’3") with VERY short lower legs makes finding boots/chaps nigh on impossible. I measure 14.5" to the back of my knee!!
I did manage to find suede-and-velcro half-chaps to fit at my local tack shop (they have a wonderful employee who’s also had GBP), but I’ve made a new goal for myself… I’ve always been fascinated with fox hunting, so I decided that, what the hell-- life’s too short; I’m going to try this fall. Yay me!
Problem is, now I’m going to need “real” riding clothes, not just schooling breeches and my grungy half-chaps…
I ordered a coat pattern from Suitability, so I’m going to have my seamstress work on that for me. But trying to find boots has been a major dilemma… I honestly cannot afford full customs, so I’ve been hunting high and low for XX-wide boots that I maybe hopefully can have tailored to fit.
I think I might have found a pair from Nittany Boots-- I emailed her about semi-custom options, and it just so happened that she had a pair that were returned because the factory transposed the measurements on the order-- the boots are 18" calf, 16" high. They should be arriving any day now, and I can’t tell you how hard my fingers are crossed that they might actually come close to fitting.
Here’s my question… I really would prefer not to have zippered boots, and this pair from Nittany are no-zips. I’m figuring I’m probably going to have to alter them somehow-- is it possible to have GUSSETS put in, instead of a zipper?
PS-- I love love LOVE all things Irideon-- I own 3 pairs, and if I could afford it, I wouldn’t wear anything but. They’re just so comfy for me, I adore them completely…
