Here is a solid write-up and content strategy for your brand:

Photos of "big" iced coffees with cute straw covers, vintage digital cameras, and pastel-colored room decor.

Pointelle knit tops, pleated mini skirts, lace-trim camis, leg warmers, and oversized zip-up hoodies.

Pastels (baby pink, lavender, cream) paired with stark neutrals or "cherry red" accents.

"The 5 'Big' accessories every 'Baby' aesthetic needs." The Tone of Voice

Start in oversized pajamas (the "before") and transition into a curated, lace-heavy "Teen Baby" look.
