The Beauty of the Bow
When a ribbon is tied in a bow and placed on any gift, it instantly adds beauty, appeal, and mystery. These are some of the reasons women love to be associated with the bow tie, it allows them to basically gift wrap themselves and present what they have to the world.
Placing the bow tie ribbon tattoo on the wrists, neck, or even legs, symbolizes something more than meets the eyes. If you want to know what is under that gift wrapping, you have to be willing to peel apart a few of the outer layers before you get your reward.
These bow tie tattoos are symbolic of charm, beauty, but they can also have a very deep meaning for the wearer.
Tie Up Loose Ends
The bow tie tattoos appeal to those who are ready to move forward and leave behind a past they have finally come to terms with. This tattoo is all about the tying up of loose ends, butting a bow on the past and moving forward in a positive direction.
Women today love the bow tie either in string, ribbon, or lace design, part of what gives it that beautiful appearance. Women revere the bow tie tattoos because they symbolize a cool attitude, being liberal, being able to stand on their own.
These bow ties made of lace scream femininity, a representation of embellishing something to make what is inside even more valuable. These tattoo designs are actually a small fashion statement that reveal a sampling of the personality of the women inside.
