It's one thing if she's wearing something inappropriate for the occasion. But, as you admitted in the comments, she's been fine. The problems you have stem from your own personal preferences. But guess what! She's her own person with her own preferences that supercede yours when it comes to her own body. She's not your Barbie doll that you get to dress up.

No one's preferences are the same and it's asinine to impose yours onto her over a few articles of clothing you do not like. Her wardrobe (or anyone else's) does not exist to please you 100%, it's for her.

And with that said, I can guarantee there are clothes of yours that she doesn't like on you either. I cannot think of one person who likes every single piece of clothing their partner owns because it would be nearly impossible for 2 individual people to have the exact same preferences. And it's more than clothes. You are inevitably going to choose hairstyles, accessories, fragrances, and other products that she won't like and vice versa. You will never find someone whose personal preferences 100% align with yours, and it's controlling to impose that on her/anyone.
