Feeling out of place but really wanting to be a good girl

Daddy gave me an allowance to purchase a silk nighty for easy access 🤤 but I’m having trouble not being embarrassed because I don’t want one that will make me feel like I’m cross dressing.

I’m a cis/het female and daddy is my husband of six years. I’m somewhat feminine but lean towards tomboy think, sporty spice. How do I stop being too embarrassed to wear cute feminine things?!
