General Beauty
These are classic beauty spells and general beauty spells.

MIRROR, MIRROR:
On a Friday during a full moon look into a mirror, naked and visulaise the body you want.  Candles and incense may also be used.  This can be repeasted as many time as wished.

BEAUTY SPELL 2:
This spell is best preformed during the Full Moon or on a Friday during a Waxing Moon.  You will need a bowl of spring water, herbs associated with beauty like catnip and lavender, a mirror, and a white rose that has been seperated from its stem.  Purification of some form, like a ritual bath, is also a good idea before preforming this spell.  Cast your circle and allow yourself to become centred and calm.  Then, stand or sit facing the West, pour the spring water into the bowl and facing the West say:
"I hail to the West the forces of water
Hear and aid me in this Magick tonight.
Grant me your beauty,
Shape and form this face and body
and let me radiate with self love.
With harm towards none,
and for the free will of all,
So mote it be."
Set the rose afloat in the bowl of water and stir it with your fingers three times around clockwise.  Next, take the flower out and hold it in your hands and say:
"By the powers of the West
By the forces of Water,
I charge this flower with love.
Beauty is here,
It shines with the power.
Beauty is here,
Contained in this flower."
Now put this flower in a box with the herbs to remind you of your beauty.  If someone needs the power of love and beauty tell them that you have blessed the rose with these things and give it to them.

BEAUTY LIKE THE MORNING DEW:
This spell should be preformed on Beltane (May Day) in the early morning.  According to Celtic folklore, a woman who goes out at dawn on May Day and watshes her face in the dew will be irresistibly beautiful.  Traditionally this should be the dew on a hawthorn tree, but I think rose bushes, primrose, lilacs, and honeysuckle is probably also a good idea.  In Arthurian legends Queen Guinevere practices this and this practices is also seen in an Old English nursey ryhme.
The fair maid who, on the first of May,
Goes to the fields at the break of day,
And bathes in dew from the hawthorn tree,
Will ever strong and handsome be.
