What neckline is most comfortable for dancing?

The answer

Necklines that stay secure when you move, such as a V-neck, scoop or square neckline with supportive straps, tend to be comfortable. Test it in the fitting room by raising your arms, bending forward and turning, and check that it does not gape. Strapless and off-the-shoulder styles need a secure fit, and sleeves on off-the-shoulder styles can limit arm movement. Also consider hugging many people.
