Why do we do that?

1. Designating a ring finger.
The traditional belief is that the "love vein" runs directly from the heart to the tip of the second to last finger on the left hand. The earliest use of jewelry to signify a bonding was often chains and bracelets. This evolved to the use of the symbolic ring. In ancient Egypt, the Sun and the Moon gods were feared and worshiped. A ring was a symbol of these spirits, both of whom were also related to the home and hearth. The endless circle showed the eternal nature of the bond, while the open center was meant to be a doorway to things unkown.

18. Groom throws garter.

This is one of the oldest surviving wedding traditions and has evolved from the Middle Ages to the fun activity that it is today. It started in the 14th century in England, when wedding guests considered it lucky to get a piece of the bride's clothing. In order to preserve her dress, the bride started throwing her garter at the male guests. As the male guests became rowdier, they tried to tear the garter off of the bride's leg themselves. In an attempt to preserve his new wife's dignity, the groom started to remove the garter himself and toss it to the single men. Another old English tradition surrounding the garter had the wedding guests following the bride and groom into their bridal chamber. They would throw discarded stocking at the couple and the one that hung on either the bride's or the groom's nose was thought to be the next to get married. Today most brides wear two garters. They have one that they keep and one to throw away. They usually wear them on the right leg. It was popular for the groom to remove the garter with his teeth, but in recent years, it has been viewed as more appropriate for the groom to remove the garter with his hands. He then tosses the garter to all of the single men in attendance. The man that catches the garter is thought to be the next to get married. 

Something old, something new
Something borrowed, something blue
And a silver sixpence in her shoe.
A sixpence is a coin made of silver and worth six pennies. So this wedding tradition is definitely English, and many sources say that it began in theVictorian era.
Each item in this poem represents a good-luck token for the bride. If she carries all of them on her wedding day, her marriage will be happy. "Something old" symbolizes continuity with the bride's family and the past. "Something new" means optimism and hope for the bride's new life ahead. "Something borrowed" is usually an item from a happily married friend or family member, whose good fortune in marriage is supposed to carry over to the new bride. The borrowed item also reminds the bride that she can depend on her friends and family.
As for the colorful item, blue has been connected to weddings for centuries. In ancient Rome, brides wore blue to symbolize love, modesty, and fidelity. Christianity has long dressed the Virgin Mary in blue, so purity was associated with the color. Before the late 19th century, blue was a popular color for wedding gowns, as evidenced in proverbs like, "Marry in blue, lover be true."
And finally, a silver sixpence in the bride's shoe represents wealth and financial security. It may date back to a Scottish custom of a groom putting a silver coin under his foot for good luck. For optimum fortune, the sixpence should be in the left shoe. These days, a dime or a copper penny is sometimes substituted, and many companies sell keepsake sixpences for weddings.
