She means she'll be ready in five minutes.
Unless, she notices that her hair got mussed up when she slipped on her dress/gown, and she needs to fix her hair again; or there is a run in her silk stockings, and she needs to replace them; or she dropped the back of her earring and can't find it, so she needs to rethink her jewellery for the evening; or she broke her heel and needs to pull out another pair of shoes, which would not go with the little black dress she was going to wear, so she needs to change into her electric blue cocktail dress instead, which means her make-up colour palette needs to change.
All these things are beyond her control, and therefore cannot be factored into her calculations.
Any other suggestions for translations of woman-speak to man-speak, please place in commbox.

Scripture to keep in mind
Six things there are, which the Lord hateth, and the seventh his soul detesteth:  Haughty eyes, a lying tongue, hands that shed innocent blood,  A heart that deviseth wicked plots, feet that are swift to run into mischief, A deceitful witness that uttereth lies, and him that soweth discord among brethren.  My son, keep the commandments of thy father, and forsake not the law of thy mother. ***Cf:Douay-Rheims Proverbs 6: 16-20
