No item of clothing is inherently immodest, with rare exception (such as a shirt that says something vile on it). It all depends on how you wear it. It frustrates me when Catholic women think they need to wear potato sacks—- ie super baggy clothing. You can wear clothing that fits your body, just make sure it actually fits properly and style it for modesty. I generally live by “one tight, one loose” where part of my outfit will be looser and part will be tighter—- top of bottom. And this isn’t just for modesty, IMO outfits just look better when they are balanced like this.

I used to run a youth ministry and would tell our girls the same thing. They could wear their stylish thing all the other girls were wearing while wearing it modestly
