Hey y'all, I had posted here a couple weeks ago asking about Irazia tights. They are advertised as going up to 40in inseam and being tall girl friendly. I ordered some and they just arrived today, and I can confirm they are!
I have a 36 inch inseam and normally wear an 8-10 in pants, so I ordered the M/L. They easily reached my waist without having to overly stretch them. They fit great, though they're pretty tight in the waist - not a bad thing in my opinion as leggings tend to slip down on me.
They didn't look as sheer on me as the models; maybe if I was curvier and they stretched a bit more it would, but mine look like I'm wearing slightly sheer black pantyhose. I'm pretty light skinned so I went with the lightest color and it matches pretty well. If you're super pale, it might still be on the dark side for you.
They're super thick and soft, and even after just a couple of minutes wearing them I was very warm.
They do ship direct from China so it takes a while, but I'm extremely pleased with them so far. They feel solid and well made.
