What to wear with a long purple sweater vest/tank top? - purple sweater

My mother gave me a life-long purple sweater, Primark and I have no idea how to use it! A little light, the color purple brightish is just below my ass and has a deep V
Who knows how I can use it and give it the appearance of Nice? I thought, as skinnies black T-shirt with long sleeves and black converse? Thank you! :)
