Watch your little fashionista create the foundation for her own unique look with a girls' plain T-shirt dress. A clean and simple design means she can twirl her way across the dance floor without interruptions to the newest TikTok routine. All-over sequins will make her the iridescent star of the show, while comfy trainers will have her dancing the night away (until 10pm, anyway). Saturday night sleepovers just became super stylish with our plain oversized T-shirt dresses. An easy-to-slip-on number will let her conduct her own fashion show in her bedroom with her besties, then swap her ballerina shoes for slippers when the sugar crash hits. Give our little-girl T-shirt dresses an edgier vibe by adding a biker jacket and chunky boots – the perfect autumn look for a mum-daughter shopping trip to her favourite RI store.
