#1 The wedding dress
Think nothing too revealing, sexy, or shocking. If anything, most royal brides, or celebrity brides who look like princesses themselves (we're looking at you, Angelababy!) opt for romantic long-sleeved dresses that are classics. Think A-line gowns or ball gowns that won't look out of place at a ballroom reception. Lace, commonly seen on royal wedding dresses like Kate Middleton's now iconic gown, lend feminine and vintage charm, while duchesse satin and heavier fabrics impart a regal air.
Although, figure-hugging silhouettes (take a leaf out of Myolie Wu's beautiful mermaid-cut dress) or off-the-shoulder designs are fine, as long as you don't reveal too much (like strategically-placed cut-outs or exceedingly low backs).
#2 Hair and makeup
Again, your hair and makeup shouldn't be anything too elaborate. We're referring to simple, sleek hairstyles like a low bun, chignon, down-do. If you're wearing your hair short, a tiara or bejewelled clip to go with your veil is what you should be looking at.
With makeup, just know that princess brides don't go for anything that's too heavy or modern. So that means no dramatic eyes or overly bright hues. Most of the royal brides we've seen wore makeup that accentuated their features, or slightly smoky eyes.
#3 The wedding veil
There's no fixed rule when it comes to veils - Catherine, the Duchess of Cambridge wore a fingertip veil while her late mother-in-law, Princess Diana of Wales, opted for a cathedral-length veil to match her impressive gown and train. But cathedral or floor-length veils generally add drama to your look.
If you're hoping to carry a sumptuous bouquet with lush blooms, you can skip that thought. Most royal bouquets are usually posies and often in classic white, or another accessory like Princess Grace Kelly of Monaco's lace-wrapped prayer book.

5. Shoes and other accessories
Gloves, pearls as well as closed-toe heels are usually the accessories du jour for royal brides. Gloves and pearls lend an old-world charm to the look (also apt, as royal brides - whether by blood or they're marrying into the family - come from an institution that's been around for many years), while closed-toe heels look elegant but not too modern. We also suspect that as royal brides usually marry in religious venues, appropriate footwear (read: not open-toe sandals or flats) are a must.
