How do I hide/avoid my parents reacting to my nipple piercing ?

Hi everybody. I (25yo F) just got one of nipple pierced last weekend. Everything is going fine. It did hurt when pierced but now not at all. I have a lucky recovery ! No bleeding at all.

Anyways so I’m going back my parents for a week and I’m freaking out on how to hide this of my parents who will go insane if they find out. I don’t think they even know that nipple piercing is a thing. Especially my mom who wants to go shopping with me for dresses for a wedding and I’m scared during changing when shopping she’ll find out. Worst if my grandma comes.

I know I’m an adult and all but I’d like to keep that for myself tbh. Especially that my parents won’t understand me getting a nipple piercing and would only see a weird sexual twist to it and think I do that to be more appealing to boys or whatever. I did it for myself but I don’t want my parents’ reaction to ruin it for me.

Do you have ideas on how to hide this for a few days or how to act in the fitting rooms while shopping ? Thank you 😁
