Avoid wearing tight clothes to sleep. If possible wear loose caftans indoors so that your skin can breathe.

Avoid activities that increase chafing. Wait till the irritation has passed before resuming the activity.

If the irritation is very acute, use medicated gel or powder to dry up the areas. Also dry these areas properly after a bath.

If irritation is allowed to subsist, it can lead to yeast or bacterial infections. Take steps to avoid this.

Avoid using too many chemicals like deodorants or creams. Let the skin breathe naturally as much as possible.

Antihistamines and creams for dermatitis can be used in cases of extreme irritation.

Cornstarch is also considered an effective remedy for skin chafing but it is important that you do not sweat after applying it.

Though not strictly speaking a remedy, losing weight is considered the best long-term solution to chafing. Losing weight and building muscle tone is a good way to prevent breasts from chafing against the surrounding skin. If you are a diabetic, you should also get your sugar levels tested. Sometimes long term high sugar levels can lead to yeast infections which can start after chafing.
