Yes, yes, yes to what Michelle said. As a busty woman, I find that woven tops can be super frustrating. But when you find a GREAT woven that really fits well, it can be magical. In the past two months I was fortunate enough to score some silk tops that feel beautiful and skim over my troublesome parts. One of the silk tops has some stretch built in, which is helpful.
The other dilemma I have with woven tops is that they only portray a really crisp, clean vibe if they ARE crisp and clean. I end up with wrinkles in my cotton woven tops halfway through the day. I don't like to iron (though I will if I have to) so usually steam the wrinkles out while I'm in the shower to get by in between washes. In general, though, I find that wovens take more effort and care.
My favorite knit is rayon. Some of the Michael Kors tops that Angie put into the YLF store earlier this year are a woven/spandex blend, and they stretch gently but are less clingy than a typical knit, and also seem to be holding up very well (absolutely no pilling or stretching out of shape.)
I usually keep knits confined to my upper half, but I do have ponte knit skinnies, dresses, and skirts that come into play on occasion. Having knit bottoms can be challenging because they are generally clingier and require more coverage (slips) or shapewear in order to meet my comfort and modesty requirements.
Hope that this feedback helps along with Michelle's fabulous descriptions and links.
