Help me figure out my attire.

Your dress is a touch boho, so for a regal, classic look I'd suggest move towards minimalism and away from vintage designs. How about middle part, hair down soft curls, tucked behind ears and diamond studs or pearls? You could also go for a jeweled high headband or double headband. If you like your hair back or it will be hot, consider a low bun, chignon, or beehive bun. You can don a simple veil or leave off. A cape is also very cool (and regal), but may be difficult to match your pattern. Zara has even sheer ones right now. Strong lashes, nude to pink lips. Best wishes.

You could consider sheer gloves, short like Bridgerton or long and fingerless which are en trend.
