if you feel comfy doing your own makeup for your big day, then go for it! just like if you were going to a pro, do a makeup trial and run and take pictures in different lighting to see how it looks and if you like it.
i would def reccomend MAC makeup because its a pro line that makeup artists use and they know and have makeup that looks good different lightings, for photos/videos, etc. and the best part is, even though its a little different than im sure youre used to wearing, its super light and makes you look flawless easily. it also stays on for a long time and in different weather conditions.
i started using it for pageants and now wear it every day because you can layer the makeup from light everyday type to a heavier, flawless but still natural for events and so on.
if youre looking to save money but still might want a pro to do it, you can schedule an appt at the counter with an artist and they dont charge for the application but they require that you do buy some of the products that they use, which im sure you would anyways if you were to do it yourself and you probably would want it for touchups.
my fav. products:
-studiofix powder: if you like less and light but an all-inclusive type coverage, you would love this! its a pressed powder that you can use to set a foundation but you can also use it as a foundation, powder, and concealer all-in-one if you apply a moisturizer before and apply it with a brush while the moisturizer is still wet. thats what i do for events because it gives you a more flawless finish by layering yet i do that for everyday in a lighter application. love it!
-eyeshadows: i love all their eyeshadows because they have a huge variety of colors and shimmers/mattes and they stay on until you wash your face. i have a bad habit of sleeping in my makeup (i know, terrible for my skin) but as long as i dont sleep on my face, my eye makeup is still in tact.
lipglosses: i love them! they arent really sticky and have some beautiful colors, super light feeling which might be good for you if you dont wear heavy makeup. i would just suggest wearing a little lip liner just so your lips are more defined for pictures
the makeup artists will of course be able to walk you through alll this and help you pick some great colors. and to address the eye liner, to combat that but still have great and defined eyes and lashes, i would suggest wearing fake eyelashes. you can get them in all sorts of lengths and volumes but they will really define your eyes without having to wear eye liner. a must for pics. they are really different to wear but i promise its worth it and after a while you forget about them
i know this is a lot and i apologize but if you have any more questions or need to me to elaborate, tell you about my fav. things, just send me a message! good luck!
