Ladies, thank you so much for the responses! This has been very helpful! These are wonderful suggestions so I'll be taking A LOT of notes!
@Suz: thanks for the heads up on silk button downs! I'm not one to favour clingy clothes in the heat! I actually recently purchased a DKNY silk shirt from Marshall's but I'm debating weather it not its a good idea to keep it. I'm going to keep what you have said in mind. Also - the maintenance of silk is not looking good for me. I dislike ironing, but I guess for a few loved pieces (not button downs!) I might be willing to iron.
I have silk/cotton fabric laying around at home and plan to make a top out of. The fabric isn't as fluid as I would like, but I'll see how I can make it work for me.
@Claire: i actually like rayon and viscose fabrics! They are so easy to care for and very much compatible with my busy grab-and-go lifestyle! I am more likely to purchase those fabrics over cotton and linen because I need the fluidity (unless they are jackets and pants). I was in AT recently and found a white linen jacket that I like. It has a polyester lining, though so I'm hesitant about purchasing.
@deb: I actually wear a lot of poly blend pants and even jeans. I find the "non-digging" to the waist types have this fabrication. And they are indeed better for winter!
@Laura: I heard of nylon being breathable! I once owned a top by Sweet Pea which is pretty much made of double layered nylon. It's surprisingly breathable than most clothes I owned!
@Dee: I'm exploring the Eileen Fisher brand a lot. Ever since Shannon started talking about it, I've been her silent lemming (lol!). I, too, have a medical condition where I can't take too much heat! I'm prone to breaking out in rashes if I sweat too much. The doctor actually told me to stop wearing wool unless it's outerwear!
@rute: thanks for the heads up on silk and stains! I've always been paranoid about sweat stains so it's a good thing you mentioned this! I do wonder if there are cotton fabrics with a fluid drape. That would be ideal for me.
@thistle: one of the reasons why I don't own a lot of silk is due to the maintenance. I need something easy to maintain as I'm always on the go. This is why I look for rayon as a worthwhile substitute.
@Inge and Ummlila: I walked in a Massimo Dutti store and thought the clothes were so well-made! I'll look into it. Hopefully they have something for my preferred colour scheme (I default to high contrast black and white).
@MrsK: I am looking to purchase the Wilfred Chevalier jacket and a silk dolman Babaton top from Aritzia. I find their fits a bit odd though - as if they're made for smaller women with narrow shoulders. I like Club Monaco and am waiting until a black tunic and it's taupe version goes on sale.
@Mia: I really like modal as well. I think Jockey makes some of their camis/undies in that fabric! Boo! Too bad on the DVF top. Is it loose, at least?
@Mo: Forever21! Interesting! I'll likely look online rather than go to the store since I always get overwhelmed! Thanks for letting me know! I'm quite surprised to find out they have linen!
