I took a chance a couple of weeks ago, and ordered a button-front, short-sleeved big shirt from Woman Within. I don't usually order shirts like that because the buttons gape across the rack-o-doom, the shoulders usually come halfway down my upper arm, and the sleeves are either too tight or way too loose.
Well, lo and behold, when it arrived today, I tried it on and it fits just as well as one I would have made! The kicker for me, it was on sale for $9.88. I fully intend on going back and ordering a couple more in different colors (this one is purple-y mauve, gray, & black vertical stripes of varying widths and I love it). I plan on wearing it with my jeans or my black knit slacks (may have to see if I can find some purple slacks too). I might even get a couple of tanks to wear under it with it unbuttoned (wow, I'm not into fashion, but this has really opened my eyes to my options on dressing and looking good).
I also got a pair of hunter green knit slacks (those were on sale for $9) with pockets to replace a pair FatCat clawed the hell out of (he has a problem retracting his claws, and is too old to have de-clawed). I have several green shirts I can wear with them, but I want to get a couple more pairs in colors other than black and navy blue and brown (I have enough of those colors....lol).
I had my reservations about Woman Within when I first got a catalog from them, but with the success I had with this order, I think I may try ordering other items from them (if it doesn't fit the way I want, return shipping is free, so that's another point in their favor).
