Song of Solomon 7
How beautiful are your feet in sandals,
O prince’s daughter!
The curves of your thighs are like jewels,
The work of the hands of a skillful workman.
2 Your navel is a rounded goblet;
It lacks no [a]blended beverage.
Your waist is a heap of wheat
Set about with lilies.
3 Your two breasts are like two fawns,
Twins of a gazelle.
4 Your neck is like an ivory tower,
Your eyes like the pools in Heshbon
By the gate of Bath Rabbim.
Your nose is like the tower of Lebanon
Which looks toward Damascus.
5 Your head crowns you like Mount Carmel,
And the hair of your head is like purple;
A king is held captive by your tresses.

Commentary:
It is also important to notice that this is the third extended description of the maiden’s beauty (previously also in Song of Solomon 4:1-5 and 6:4-9). These three descriptions may be compared to the single description of the beloved’s appearance (found in Song of Solomon 5:10-16), which was not even spoken to the beloved himself, but to others about the beloved. This comparison strengthens the impression that it is far more important for a woman to be assured of and confident in her beauty than it is for a man.

I would also note that it is important for a woman (and man) to care about their beauty. As time ticks by we allow ourselves to sit in a rut physically, and we blame it on circumstances. This apathy allows the enemy an opportunity.
Always do your best, to BE your best for the one you love. It should be the same mentality we have when serving our Lord. Everything should be the best!
