When It Comes to Sexy Halloween Costumes, Jennifer Lopez Is an Endless Source of Inspiration

Jennifer Lopez's breakthrough role in Selena launched her to superstardom. She rocked some of Selena's most iconic looks while playing la Reina del Tex-Mex, but nothing says Selena more than this jumpsuit.

• What to wear: Find a vintage sparkly jumpsuit with flared legs and a cutout to show off those abs. Bonus points if you choose to rock a MAC x Selena lipstick.
• How to act: In this scene, Jennifer reenacted Selena's last live performance, and she stole the spotlight on stage. You can do the same by dancing and twirling everywhere you go with some Tex-Mex flair.
