For the "Yaluvme" logo blue heather rolled-up V-neck t-shirt, you could consider a design featuring a minimalist and modern font for "Yaluvme" in a vibrant blue hue, perhaps with a subtle gradient effect to add depth. Below the logo, you could incorporate a small graphic element, such as a heart or abstract symbol, also in blue, to complement the text. As for the t-shirt itself, a soft heather blue fabric would provide a comfortable and stylish base, with rolled-up sleeves adding a casual and relaxed touch. Overall, the design would convey a sense of modernity, simplicity, and laid-back charm.
