How do you people shop exclusively online? Do you just know how some of these retailers fit you already, or do you just order the standard size you need? I've never had clothes fit me the same way from store to store. Hell, half the time they don't fit me from pant to pant.
I just had a nice run of shopping thanks to my wife's substantial discount at Barney's. Now that she's moved on, I genuinely stick to shops like Banana Republic & French Connection for work/dressier clothes, Old Navy & American Eagle for shorts and casual stuff, and eBay & shows for t-shirts. But then again, I let my wife dress me. It's easier that way.
