As far as sequin pants go, this is my 3rd and final pair I have to show you. This one is completely black. When looking at all 3 looks you can see that my tips for wearing sequin pants without looking too much like a discoball are to keep the top simple, or in a solid color, but also to play with different textures in your outfit.
Sequins can also be rocked in much bolder colors but if you're not sure about that, just leave it to the pro's and enjoy sequins your way ;) You can always advance to rocking sequins class 2 in the future, because they aren't going anywhere! I like to wear them whenever I want, not necessarily during the holiday season, but it's completely up to you.
