A woman says her grandmother's passion for fashion "keeps her young" - and she "slays" when trying on her granddaughter's skimpy outfits.<br /><br />Stephanie De Pena, 30, and her grandmother, Mariah, 85, who has dementia, are exceptionally close and the pair love shopping, dressing up and dancing together.<br /><br />Mariah used to work in a factory making clothes and retired in her 60s before being diagnosed with dementia four years ago in 2019.<br /><br />She now uses a walking frame to get around, but it doesn't stop her from swaying her hips.<br /><br />Stephanie dresses her grandmother in outfits from her own wardrobe - and says she "slays" the looks which she shares on social media.<br /><br />She claims her grandmother's doctor even encouraged the pair to keep making fashion and dance TikToks to keep Mariah's mind active. <br /><br />Stephanie has her own boutique and her grandma helps her as her assistant - picking and packing clothes.<br /><br />Stephanie, who lives in Pennsylvania, Philadelphia, US, said: "Our love for fashion has always kept us going.<br /><br />"She's always been there for me through the good and the bad.<br /><br />"She doesn't remember things and sometimes doesn't know who people are, but it's amazing to see how when we're recording she remembers everything.<br /><br />"Her doctor said to keep it going as the videos seem to be helping."<br /><br />In 2021, the duo uploaded their first TikTok video and it blew up and they now have 176.3k followers.<br /><br />The pair have continued to create dance and fashion content and Mariah even dresses in Stephanie's clothes.<br /><br />"She absolutely loves it," Stephanie said.<br /><br />"Before dementia, she always had her nails done and there was never a single wrinkle in her clothing.<br /><br />"She doesn't care as much about her appearance now but she definitely loves any bright colour.<br /><br />"She doesn't like to be neutral and has to be bright. She often wears blues, pinks and yellows.<br /><br />"Even when she's in her grandma clothes she has to be bright.<br /><br />"Her favourite outfit is a three-piece blue set but she realised the top is a little shorter than she thought."<br /><br />The family discovered Mariah had dementia when she kept leaving the cooker on by accident in 2019.<br /><br />After the diagnosis, the family decided they wanted to care for her.<br /><br />Mariah hasn't moved away to ensure she sees her grandmother every day and her mum, Maribel, 48, is her full-time carer.<br /><br />Stephanie added: "We're a big loving family and we keep her busy.<br /><br />"Just seeing her smile makes things so much better - she's always laughing."<br /><br />Stephanie opened her own clothing boutique, Denver, in September 2020.<br /><br />She said: "I've always loved fashion and creating content with grandma gave me the confidence to start my own business.<br /><br />"Growing up I was a tomboy, but grandma always wanted me to wear dresses.<br /><br />"I got into fashion in high school when I realised it was a form of expressing myself and art.<br /><br />"I would say I'm not very conservative - I like tight and bright clothes and I'm colourful like my grandma.<br /><br />"We have the same sense of style, she loves when I'm all dressed up."<br /><br />When they're not making videos, the pair like to go shopping and spend hours dancing.<br /><br />"She dances with her walker - she just holds on and moves her hips," Stephanie said.<br /><br />"She doesn't speak English so I translate the lyrics into Spanish and, of course, she loves Spanish songs too.<br /><br />"Right now, her favourite song is 'Flowers' by Miley Cyrus."<br /><br />Mariah is also grandmother to Stephanie's siblings - Leslie, 20 and Luis, 20.<br /><br />Stephanie said: "My favourite thing about grandma is her heart - she is the most loving person I have ever met.<br /><br />"When you're with her you can feel the love - she's just an inspiration to me."
