I recently got a copy of Singer Perfect Plus: Sew a Mix-and-Match Wardrobe for Plus and Petite-Plus Sizes to review, and it's taken me a while to get to it, being neither perfect nor plus-size.
Perfect Plus is a very straightforward book, nothing fancy. You're not going to get any couture techniques here, or anything too fashion-forward or art-to-wear. This is primarily a book for petite, plus-size women who are not fashionistas, but are frustrated with the tatty stuff they see in stores (or with the price tags on the nicer plus-size garments) and who don't have a ton of sewing experience.
The book includes four patterns (a blouse with collar & sleeve variations, pants, an elastic-waist skirt, and a jacket with very nice pockets) and many, many pages of help on how to choose fabrics, construction tips, and fitting.
If you are newish to sewing, need a very basic petite plus-size wardrobe and want a lot of hand-holding, this book is ideal for you. These garments are so simple, though, that your fabric choices are going to be very important. Cheap polyesters or badly-designed prints will make these look like a dog's breakfast — upgrading to better-quality cottons and silks and good buttons (and taking your time with construction) will make all the difference here.
If you're already an experienced sewist or you want garments with more advanced design elements, I'd save your money — there's nothing here that you probably haven't already made on your own. You'd be better off getting a good book on fitting patterns (like Fit for Real People) and altering patterns that you really like.
I don't need to keep this book, so I'm giving it away … the person who writes me the best haiku about pockets will get it! You can email your verse or leave it in the comments. (If you leave it in the comments and you want the book, make sure there's a way for me to reach you.)
