first “big girl” drink ideas?

I’m someone who rarely (if ever) drinks. I have an extremely low tolerance to alcohol so thats a part of the reason i avoid drinking whenever possible. Ive only ever drank ciders and champagne but i do want to step up my game a bit. Im not a fan of the taste of alcohol but I’m genuinely down to try any drink that WILL NOT get me wasted in a second. I need something basic that every bartender will know how to make,but it should also taste nice and not be too overwhelming for a beginner!
