Swimsuit season is in full effect, and we're taking notes from Jennifer Aniston on how to do it right! The 56-year-old proved string bikinis aren't just for teens - they're body-flattering at any age. And while her pick is a splurge at $450, we found an affordable version that's 94% less! Aniston was spotted wearing the Eres Mouna & Malou Bikini set while in Mexico. She paired it with a floppy, woven beach hat and oversized shades, proving that a simple string bikini is easy to style with vacation necessities.
