Becky, I think sometimes it's just that the fit model is wrong for your particular shape. This is why it pays to do a huge amount of reconnaissance in brick and mortar stores. I tend to go on missions when I'm in a large city, not necessarily to buy anything, but simply to try on a specific company's or designer's clothes. Even if they don't have my correct size in the store (and this is typical), I try the thing I think is going to be closest to my size. From this I get a sense of whether the overall fit model is suited to my body. I still may not know my exact size for a specific item, but looking at the size chart and reading reviews gives me more information to consider before I order online. I look for reviews by people who claim to have a body type similar to my own.
I also consider the item in light of Angie's recommendations for body type. For instance, a lot of reviewers will say things like "Really tight in the bust, terrible!!!!" but that probably means it will actually fit me.
On the other hand, if I'm looking for a fluid fit tee or knit top, I skim past complaints that an item is "too oversized." What I find is that especially in a time when silhouettes are transitioning, some reviewers won't be as up to date on trends as most readers of this blog. So they may be looking for a very fitted look when fluid is trending (or the reverse). I try to weigh that in my decisions. I love reviewers who provide a lot of detail about their body size and shape and their fit preferences and now when I review an item I tend to include that info. for others.
Naturally, I still have a lot of misses, but I get a surprising number of hits this way. I have even successfully purchased bras using this method. It does involve a fair bit of research.
I think Angie's probably right about those AE shorts. A big quality control boo boo. Their loss....
I agree with Angie that on the whole sizes have crept up rather than gone down. Even designer jeans seem bigger this year than last. (I know they got smaller there for a year or so...but that seems to have reverted.)
I've struggled to find tops this year that are not too wide in the body -- and that is even with all my careful reading of reviews.
In the 90s I wore a dress size at least 3 sizes bigger than my current size. I am in fact a bit slimmer than I was then, but maybe by one size. In designer clothes, I take a larger size than in most regular American clothes.
