When it comes to the mother of a bride, there are two basic options: complement or antithesis.
Complement is defined as an item that fills out something else, making it more complete.
Antithesis is defined as being opposite in nature or characteristics.
So if complementing your daughter means being natural and relaxed (which will definitely show up on camera), then the antithesis would be going full glamor with heavy contouring and dramatic eyeshadow.
It's best for mothers of brides to go with their own personal style rather than trying too hard to match their daughters' aesthetics or preferences for weddings (whether they're traditional or nontraditional).
The best thing you can do at this stage is to be yourself—that way everyone else will love who you are!
Remember, you don’t have to look flawless, but you do need to be you.
