Undergarment Lines
Your clothes will only look good on you if you are wearing the right undergarments. It does not matter how nice your outfit is because it will not look right if your underwear is too tight or if the bra shows through. Seamless underwear is the way to go to avoid any fashion mistakes. You do not want to go through what Faye Dunaway did, right?
Jersey Fabric
Even though jersey is comfy, it is more than capable of accentuating all the wrong parts of the body. If you want to hide certain body parts, you are better off wearing cotton, wool, and silk. After all, jersey has a tendency to cling. If you really like the fabric, the best thing to do is to buy loose pieces or sheets.
