The hairdresser said my wedding makeup was overly bold

The wedding is approaching and I’m having trials with my hairdresser. She suggested a very different, quite bold makeup technique. She says it will look great, but the thought of walking around all day with heavy makeup that doesn’t feel like ‘me’ is bothering me. I don’t want to look like I’m wearing a mask on my face. How can I politely decline, or do you think I’m being too picky?
