Your Disguise check result determines how good the disguise is, and it is opposed by others' Spot check results. If you don't draw any attention to yourself, others do not get to make Spot checks. If you come to the attention of people who are suspicious (such as a guard who is watching commoners walking through a city gate), it can be assumed that such observers are taking 10 on their Spot checks.
The effectiveness of your disguise depends in part on how much you’re attempting to change your appearance.

Usually, an individual makes a Spot check to see through your disguise immediately upon meeting you and each hour thereafter. If you casually meet many different creatures, each for a short time, check once per day or hour, using an average Spot modifier for the group.

Yes. You may try to redo a failed disguise, but once others know that a disguise was attempted, they’ll be more suspicious.
- Magic that alters your form, such as alter self, disguise self, polymorph, or shapechange, grants you a +10 bonus on Disguise checks (see the individual spell descriptions). You must succeed on a Disguise check with a +10 bonus to duplicate the appearance of a specific individual using the veil spell. Divination magic that allows people to see through illusions (such as true seeing) does not penetrate a mundane disguise, but it can negate the magical component of a magically enhanced one.
- You must make a Disguise check when you cast a simulacrum spell to determine how good the likeness is.
