So I'm extra salty today, just to warn you. And this may be more than a bit disjointed.
I really like cov.er.sto.ry 's selection. Yes there's 11 Honore, which is great, but overall more traditional. I know there are indie designers that are more size inclusive, but they can be hard to track down. So more edgy independent designers in larger sizes, yay!
Intermix (now owned by GAP) is a trendy resource, not size inclusive.
Forward (FWRD), same.
Also FYI, XL is often a size 10 or 12 US in many lines.
Universal Standard got a not insignificant amount of flack for increasing their size range downwards. Because at one point it was nice to get "cool" clothes that were exclusive to larger sizes. Personally I think they lost their edge, but that's another topic.
Yeah so, CoverStory, they start at a size 10 end around 26 US. Two things, firstly there are so many fricking designers that cater to the 10 and less. In fact for many designers that is the the top of the range. Secondly, yes there is a lacking in the size 26 and up, unfortunately this isn't in my wheelhouse, but yes it is lacking. So I won't be commenting on that.
I really really like these pants,

Similar to Nili Lotan and Rachel Comey. Nili Lotan is NOT size inclusive, Rachel Comes is hit or miss. But the line As Ever, on their website, does not include larger sizes, yes I looked. Hmmm, go figure.
But also interestingly, here's the thing. Both Nili Lotan and Rachel Comey are doing limited lines with Target this fall. Which are size inclusive. So uh, yeah $$$$ speak; however also both lines make a big deal about being made in NYC (and I'm a big Rachel Comey fan)

I could make all sorts of comments about it's ok for down market stuff to be size inclusive, but quelle horreur, their actual mainline...

ETA to sum it up, I don't have a lot a sympathy to those sized out (down) of this website

ETA 2: I’m hugely in favor of CoverStory and hope they expand, and also maybe some of the lines realize they can offer extended sizing on their own sites.
