Reddit mentions of The Lucky Shopping Manual: Building and Improving Your Wardrobe Piece by Piece

Alright, here are the books I've dug up on Amazon so far:

Highly rated, seemingly top-tier

• The Science of Sexy
  
• How Not to Look Fat
  
• The Pocket Stylist
  
• The Lucky Shopping Manual
  
• Style on a Shoestring
  
• The One Hundred: A Guide to the Pieces Every Stylish Woman Must Own
  
  Also seem to be recommended
  
  
• The Style Checklist
  
• Before You Put That On

This book would make my day/week/month by inspiring me on my quest to feel good when I see myself in the mirror.

I'm not sure if these are exactly what you have in mind, but I really like The Pocket Stylist and The Lucky Shopping Manual. The Pocket Stylist has a good explanation of silhouette and proportion plus some advice on how to organize your closet. The Lucky Manual has good tips on fit and how to put things together. They are both a few years old and somewhat dated, but I have found their more generalized advice to still be relevant and helpful.

May I recommend some books that can help you determine your shape and how to dress it, and what to look for in terms of quality when shopping? Then based on that you can decide where to shop because some stores are better for certain shapes.

The Science of Sexy: This book accurately determines your shape and shows, in drawings, what is going to look both great and horrible. It does this for each shape at different weights, too -skinny, hourglass, medium hourglass, plump hourglass for example. Whichever your shape is, there's a blurb about what great assets you have :)

The Lucky Shopping Manual: Really detailed about what happens if your pants are too droopy (you get grandpa butt) or your winter hat is too small (you look like a sixth-grader) or your pool-side hat with sunglasses is too big (you're suddenly Joan Collins.) But then it also give ideas for shaking things up. Also provides suggestions for a realistic capsule wardrobe. Describes what to look for when shopping and how to fit things when trying them on.

What Not to Wear: (the original with Trinny and Susannah) really explains in pictures how to dress your shape when it comes to sleeves and fabrics as well as necklines, etc.

The Pocket Stylist: Suggests a very classic capsule wardrobe.

You can get information online but in less detail. Basically an hourglass looks great in v-neck tops, wrap tops, scoop neck tops, a-line skirts, pencil skirts, flesh colored pointy heels (not stilettos on the end of shapely legs, slightly sturdier), jackets with one or two buttons, high-waisted pants, and v-necklaces that aren't chokers but aren't too long. Yeah, necklaces drape over a boob if they come too far down :)

Whereas sheath dresses tend to mask your shape, turtlenecks and jackets with a lot of buttons hide the fact that you are big on top because of boobs, and cap sleeves aren't supposed to look good. Kitten heels generally don't work, either.

I'm not sure if you have InStyle or Lucky in the UK, but both of those have really great sections where they show you outfits piece by piece. There should be some magazines like in the UK?

I think your best bet, though, is to stock up on the classics. You can find lists like this all over the place: http://www.luckymag.com/style/2010/12/10-classic-pieces, but they're a really great place to start building your wardrobe. After you have those covered you can start mixing in more trendy pieces.

If you want to get a little more in depth into how to build a wardrobe, I've found this book incredibly helpful: http://www.amazon.com/Lucky-Shopping-Manual-Building-Improving/dp/1592400361

While the styling is starting to look a bit dated (I hope they come out with a new edition soon!), the tips on exactly what you need, how things should fit, and shopping in general are super helpful.
