2. Are tankinis still in?

Yes, tankinis are making a big comeback, but the 2021 versions are a bit different than the ones we all loved in seventh grade. The current tankini trend involves a top style that's a bit longer on the torso, hitting right around the bottom of your ribs.

3. Are tankinis frumpy?

Designed to be an alternative to the bikini, the tankini is a popular style for a reason. However throughout out the years, they have received a reputation for being a little frumpy and unflattering. Recently though, the tankini has seen a revival and lots of big style improvements.

4. Which tankini is best?

Best Overall: Yonique Blouson Tankini The best-seller—which has more than 2,600 five-star ratings—has a loose, flowy design that modestly cinches.
