I've mentioned before that there are an unusually high number of former Teen titleholders returning to compete this year and for the fourth or fifth year in a row South Dakota has more than one competing. Last year's first runner-up Kalani Jorgensen, who was Miss SD Teen USA 2012, is back, as is Miss SD Teen USA 2010 Alyssa Hustrulid who was second runner-up in 2016 & 2017.
Other than Kalani & Alyssa there are no other former Miss runners-up competing this year, but last year's Teen third runner-up Julia Gesling has moved up to the Miss division this year.
In the Teen competition, Shelby Specht is the only returning Teen semi-finalist. There are four non-finalists returning this year.
