Find a mixing bowl, a tub, a basin, or a bucket that is large enough for the hat and the water. Make sure the container is clean. Add warm or cool water, meaning roughly 65-80 or 18-27 or less. This is essentially room temperature water. Never use hot water, which is roughly above 90 or 32. Hot water will shrink the wool fibers. Set the hat into the bowl or basin before you add water to make sure it will fit in the container once the water is added. Choose a wool-specific detergent like Woolite or Persil Silk & Wool to make sure it is mild enough for the hat. Measure out a small amount and pour it into the water. When using powder detergent, agitate the water to make sure the particles dissolve completely. If you can't find a wool-specific detergent, make sure you use a mild detergent. Baby detergent, such as Dreft, or detergent for sensitive skin, like All Free Clear, are good alternatives. Set the hat in the water and gently press it down so it is completely submerged. Hold it there until the entire hat soaks up water. This may take a minute depending how thick the weave of the hat is. Flip it over a couple of times so all sides get wet. Gently squeeze the hat and rub the fibers to let the water and detergent permeate completely into it. If possible, turn the hat inside out to make sure the inside gets clean as well. For stubborn stains, use a soft toothbrush to lightly scrub the hat. The fibers are damaged easily, so never scrub wool with a harsh brush or with hard strokes. Be sure not to stretch the hat out while you wash it, as it may not return to the proper shape. After a good wash, let the hat soak in the water for a while to loosen any remaining stains or bad smells. If you want to, put the hat into a new bowl of warm water and detergent so it soaks in clean water. After it soaks for a while, give it a quick massage again to remove anything that was loosened while the hat soaked. Take the hat to the faucet and turn on the cold water. Let the water run over the entire surface of the hat, both inside and outside, to rinse all of the detergent and dirty water off of the hat. Rinse the hat for two or three minutes.

Q: Black does have a slimming effect, and having a little black in your wardrobe is certainly advisable. Too much makes you look bland and bleak, however. Adding color into your wardrobe gives your clothing personality and makes you look cuter. Wear dresses that have a dark side panel; this will give the body an elongated look. Light pastel shades may make your body look larger, so be careful about choosing them. Bold, bright hues, on the other hand, do not have this widening effect and often look flattering. Solid blocks of color tend to work best. Huge patterns that cover your entire outfit often appear overwhelming. As a result, your curves get masked, and you may end up looking heavier. Stick with smaller patterns or patterns that are limited to one area of your body. Stay away from tops that have ruffles down the front or pants that have decorative zippers on the thigh. These details automatically draw the eye, making the parts of your body they cover noticeably in a very unflattering way. Look for unadorned pieces or those that have embellishments on other parts of your body, such as blouses with beading at the neckline or skirts with lace at the bottom hem. Dark wash jeans look slimming and clean-cut without looking bland and boring. Light wash jeans may make your legs look wider, but many medium washes also work well. A fitted denim jacket with a short waist can add spirit and liveliness to your wardrobe. Stick with medium to dark wash denims, however, since anything lighter will probably make you look heavier than you are. You can get help from someone who is familiar with matching color to skin tones or use online resources to help you. If the tones match, you will look healthy and beautiful. Be aware that what may have suited you 10 years may cause you to look washed out now, as your skin ages. Always update.
A: Break away from black. Gravitate toward bold colors. Avoid large patterns. Avoid embellishments on the widest parts of your body. Try on dark wash jeans. Consider a medium to dark wash denim jacket. Choose colors that flatter your skin tone.
