Generate a typography design suitable for a t-shirt print for 'Pixie Merch and Apparel.' The typography should be bold and eye-catching, with clean lines that stand out against a black background. Use a modern and sleek font to convey a high-fashion aesthetic. Ensure that the design looks equally striking on a white t-shirt, so the typography should remain visible and impactful against the white background. Incorporate subtle elements that nod to the whimsical nature of pixies to add a touch of charm to the overall design.
