Sleeves solve the problem that velvet alone cannot. A strapless or slinky velvet dress looks incredible in a warm room and becomes a logistical nightmare the moment the temperature drops, which at most events it inevitably does. Sleeves mean you are not spending the evening hunting for somewhere to stash a coat or draping a wrap over fabric that was doing perfectly well on its own. That is the practical argument. The aesthetic one is equally strong. A long sleeve in velvet has a richness that short sleeve or sleeveless versions simply do not match. The fabric rewards coverage. It catches light differently across a full arm, creates a silhouette that reads as genuinely dressed up rather than party ready, and works across a far wider range of occasions from winter weddings to Christmas dinners to anything that requires you to look intentional. We have been pulling together the velvet dresses with sleeves that actually earn the extra fabric. These are the ones that make the case for covering up.
