I’m getting married at the end of the month & will be doing my own makeup too
I did have some theatrical makeup training a while back, so am not overly stressed about it.
Do consider booking a bridal session at a counter like Bobbi Brown, Charlotte Tilbury, MAC etc to get a feel for what you want. My Bobbi Brown session was free and MAC charge £50 redeemable against products.
Lisa Eldridge, Andrea Ali and Mary Greenwell are the best makeup artists to seek out on YouTube.
Bear in mind you’ll be photographed lots so you need to wear a little more makeup than you’re perhaps used to, with a little more definition around the eyes in particular.
Use a decent moisturiser and then a primer first of all - I like the Bobbi Brown Vitamin Enriched Skin Base which does both jobs & smells of Turkish Delight.
Try then using a foundation which is long lasting with a medium or full coverage - Bobbi Brown stick foundation is popular for brides, as is Kat Von D Lock It foundation and Estée Lauder Double Wear (go careful with the latter as it can ‘flash back’ in photos due to the SPF).
A long wearing full coverage concealer is super useful too, particularly under the eyes, round the nose and on any blemishes. I love Tarte Shape Tape but the Revolution concealer is a good dupe for a fraction of the price.
Eyeshadow primer (Nars or Urban Decay work best for me) will make your shadows last without fading or creasing. A gel eyeliner (Bobbi Brown or Maybelline are good) with a very fine brush works well for definition plus you’ll want waterproof mascara, just in case.
Don’t forget brows - if your brows are sparse, try using a powder eyeshadow and a damp eyeliner brush to draw in strokes to fill the gaps. MAC Omega eyeshadow is my perfect brow colour and I’m an auburny light brunette.
Nars powder blushes are super pigmented with decent wear time - you can apply with a duo fibre stippling brush for a lighter effect and build it up slowly.
You’ll want to powder to keep everything in place throughout the day - try Laura Mercury translucent powder which is super finely milled.
The final step is a good setting spray - Urban Decay or Skindinavia are ace; in fact, Skindinavia make a special bridal setting spray.
Good luck!
