Well, the results are in!
Some notes first, though:
Only the first 100 answers are free for me to read, so they are the only ones included. Which, is a shame, as I noticed around the 60mark that I didn't have so many 250lbs+ answers, so when I continued to spread the survey link, I specifically called out for the heavier women. I can tell this was listened to, as the later respondents tend to be heavier, so I assume those beyond the 100 first responses would have represented that range better.
Another thing to note, is that out of these 100, only 86 people provided enough information - I had a few that answered "no idea" to all but the height for example, which is very difficult to use in any regard to tights.
To present the data, I've used the size guides that I mentioned in the original post: Evans and WeLoveColors:
According to Evans, I got 49 (57%) women as size 1, 31 (36%) as size 2 and 5 (6%) for size 3.
For We Love Colors, I got 8 (9%) for Medium, 9 (10%) for Tall, 22 (26%) for 1X, 11 (13%) for 2X, 21 (24%) for 3X and 14 (16%) for 4X.
They both use height, but one uses hip measurement, and the other uses weight, so continuing with the theory that we are very diverse, this will give very different sizes.
So, let's see diverse the results are.
For all those who fell into the "size 1" at Evans, here is what their sizes were at We Love Colors:
Well, since my theory is that most tight size-charts inadequate, so let's see how these ladies compare with their regular jean sizes:
And last, let's see how their tighs match up:
There's 15" difference between the largest and smallest thighs who would be recommended the size 1! It seems quite unlikely that these women would have much success trying to follow the chart.
Going on to those in Evan tights size 2 we see much of the same trend:
For Evans Size 3, I had too few respondents (5) for it make sense to graph. This is probably partly down to the fact that I had a bit too few of the largest ladies, and the very important reason, that it takes a lot to be an Evans Size 3: I'm pretty sure a 5'3" women with 61" hips will in many cases need at least as wide tights as a 5'5" women with 57" hips, yet the shorter women will be catagorized as a size 2.
All the women who were size 3 at Evans, were size 4X at WeLoveColors, and their thighs were between 31"-43", and jeans sizes from UK 26 to 34. Even with so few respondents, that's a huge diversity still!
So, there you have it, that's how the tight sizing compare to both each other, but also to what usually fits our bottoms as well as our actual tigh size.
In the comments section of my survey, the vast majority felt exactly like me about the sizing: It always ends up to small!
A problem I ignorantly hadn't considered was the diverse heights as well: A lot of complaints were from shorter women who always ended up with way to long, as well as to narrow, tights: This of course makes sense when looking at the typical height/weight size chart: Often the shortst heights aren't represented at all - and if you then choose only by the weight, they are made for 5'7"+ for example, as is the case for the larger sizes with WeLoveColors. Or, it will be done as Evans, where a short women will be recommened a smaller size than a taller but narrower women, thus ending up with perhaps good lengt, but way to narrow.
So, my theory that tight sizing does not match up well with actual sizes needed, is looking pretty likely!
