Sastre means "tailor," a very creative and unexpected word to find in a love song.
The singer worries his love might not be the right "fit" for the person he likes, then uses a clever metaphor: "Verás que el mejor sastre / Es hacer un desastre con mi corazón" (You'll see that the best tailor / is to make a disaster of my heart).
He is playing on the rhyme between sastre and desastre (disaster) to say that the best way to "tailor" his heart for her is to let it become a beautiful mess, showing his complete vulnerability.
“¿Qué Se Siente Que Me Gustes Tanto?” is a dreamy confession of a crush so intense it feels like a tiny revolution inside the singer’s chest. Every sigh becomes a co-conspirator, betraying his calm each time the object of his affection walks by. He is captivated not only by physical attraction but by a deeper, almost hypnotic spark he sees in their eyes, one that leaves him lost in thought and eager to give everything he has.
Yet this devotion comes with a delicious dose of fear. The singer worries his love might not “fit” the other person, joking that if his heart is the wrong size, the best tailor is heartbreak itself. The chorus repeats the burning question: “What does it feel like that I like you this much?” He admits to being scared of the other’s charm, and even promises to follow them if they ever leave with someone else. The song blends romantic longing, playful exaggeration and vulnerability, capturing the thrilling mix of hope and anxiety that arrives when you realize you’re head-over-heels for someone.
