About Tweenstyle By Stoopher

Hi! I'm Stephanie Goldstein, and I've been running my children's boutique on NYC's Upper West Side since 2010. Tweenstyle was born from 14 years of real conversations with tween girls and their parents—navigating that tricky space between childhood and independence together. I created this line because I couldn't find what my customers were actually asking for: clothes that let tweens build their own identity without pressure to grow up too fast. Thoughtful design. Soft, quality fabrics. Styles that parents trust and girls reach for on repeat. What we carry: Full-spectrum tween apparel—loungewear, athleisure, swim, dresses, and everyday essentials in sizes that fit real tween bodies. Why it works for retailers: I'm a boutique owner first, designer second. Every piece is tested in my own store before it goes to wholesale—so I know what resonates with customers, what moves quickly, and what becomes a seasonal staple. Our wholesale partners include both department stores and independent boutiques, and I love collaborating with store owners who understand their communities as well as I know mine. Our story: Tweenstyle sold out in its first season and has been featured on celebrity kids including Sarah Jessica Parker's twins. But the real validation? Customers who've been shopping with us for over a decade, and retail partners who come back season after season. Thanks for being here. —StephanieRead their story
