Jennifer Lopez certainly loves to experiment with fashion trends, but if you look closely, her style has actually stayed remarkably consistent over the years. I just wrote a story on the trends J.Lo has been bringing back every summer since the ’90s, and you might be surprised to see how she still relies on the same wardrobe classics decade after decade.

This also rings true when it comes to her swimwear, as she just shared an Instagram post wearing the most timeless swimsuit trend out there: a black triangle string bikini. Just think of it as the LBD of swimwear: you simply can’t go wrong with it. Lopez’s post has already racked up nearly four million likes and 44,000 comments—significantly more than her other recent posts.
