Not all places are celebrating the size zero, 2, or 4

Not all places are celebrating the size zero, 2 or 4, I went to try on my wedding dress the other day & all that was in store was size 22. I found this interesting, I mean, I ordered the dress and it will be here in 10 weeks or so, but I thought how odd? I can't even try it on? I think it is interesting that high fashion stores only carry up to a size 10 or so, but when I go to try on a wedding dress the store ONLY has a size 10 and up in store.
