I found this darling Merona plaid trench coat at Target yesterday, and immediately snapped it up. Not only is it stylish, but it's also treated with water and stain repellent, making it extra-functional as well. I also like that Target offers it in a range of sizes: regular misses, petites and plus-size. I happened to be lucky enough to find it on clearance for 30% off, but even at full price ($49.99) it's a pretty good deal.
To note: Target's web site describes this as a long trench, but I wouldn't call this coat long. It comes right to my knee, and I'm only 5'3". Also: Target has mistakenly listed this item as "online only", which is incorrect as I saw a whole rack of these at my local store.
