For the big night, the 18-year-old, who was crowned prom king at the event, styled a shimmering pink floor-length blazer-style dress paired with glamorous makeup. He posed in the sparkling number alongsideÂ his classmates, showing off different angles of hisÂ outfit.
His Instagram post featuring a number of snaps from the night blew up on the platform, garnering almost 700 likes and a number of comments praising the bold look.
Santiago worked with a Ciales-based designer, Melvin NegrÃ³n, to help achieve his desired prom getup.
â€œI saw three different pictures on Pinterest, and I talked to my designer, Melvin, and we combined all three,â€ Santiago tells Yahoo Style on the inspiration for his prom look.
â€œAdrian spoke to me about what he was looking for so we gathered some information and got to work,â€ NegrÃ³n shares.
â€œThe tuxedo in sequins was inspired by Manny Mua. He has a pic on Instagram with a red sequin vest, and I thought that it was extra kinda like me,â€ Santiago jokes.
SantiagoÂ says thatÂ he discussed details of his dream look with NegrÃ³n, and the designer had a number of suggestions regarding colors and detailing.
â€œHe said he would like a menâ€™s suit â€” but not a traditional one â€” some type of tail, bling to make him stand out from the rest,â€ NegrÃ³n says on what Santiago was hoping for with his prom ensemble.
The student immediately fell in love withÂ NegrÃ³nâ€™s sketch of the pink prom outfit.
Santiago says his mindset for the perfect prom look was, â€œI want it to go viral and show the world that people can be themselves.â€ Done and done.
â€œAdrian came several times for fittings, until we had the perfect fit,â€ NegrÃ³n shares. â€œThe final look was the most exciting one â€” for Adrian and for me.â€ The designer also praised the studentâ€™s confidence and attitude.
Santiago shares that the look truly felt like his own. â€œI felt like I was myself in my prom dress. I was super confident with the dress, the makeup, the nails, everything,â€ he says.
Along with the shots of his ensemble, the student posted a closeup snap of his makeup and henna designs on his popular Instagram page.
It turns out Santiagoâ€™s classmates were just as obsessed with his outfit as he was. â€œWhen I entered the prom, I saw a friend of mine, Aisha. She was in shock. I loved her facial expression,â€ he says. â€œMy classmates loved the outfit â€” even people that didnâ€™t talk to me came to me and said they loved it. My P.E. teacher came up to me and said that he was a fan.â€
The prom king had an amazing time at the prom, largely in part to his customized gown.Â â€œMy experience was unforgettable,â€ he shares. â€œI wish I could repeat that day.â€
