The best twist outs are the ones that almost mimic your natural curl pattern, but also allow you the ability to prolong your style without constant rewetting or restyling(imo). This is one of the main reasons for keeping my hair in twists. Other reasons involve the ability to minimize overall manipulation, maintain/retain healthy length, and use less product and time in styling my hair.
The pic below is of a twist out on hair that was in twists for over a week, with me wearing it out until Monday of this week. I used only Ori Organics styling products and moisturized with these products throughout those almost two weeks.
