Tips on building a lower-plastic wardrobe and not overconsuming?

Hi all! I’m trying to reduce the amount of plastic-based clothing I own while also preparing for an upcoming move, and I’m realizing I don’t have a great sense of what a reasonable wardrobe size looks like.

Most of my clothes are older or thrifted, but I still feel like I have too many. At the same time, my lifestyle requires a pretty wide range of categories: business casual, business professional (new job), church, gym/hiking, loungewear, and occasional formal events.

Two complicating factors:

* My weight fluctuates enough that I regularly cycle in and out of different parts of my wardrobe

* I’m about to add business professional pieces, and I want to do that as sustainably as possible without overbuying

I’d love advice on a few things:

* How do you decide what’s “too much” vs. a practical wardrobe for a varied lifestyle?

* How do you handle clothes that don’t currently fit but likely will again?

* For synthetic items: is your approach to phase them out over time, or keep them if they’re well-used?

* How many workout outfits do you realistically keep in rotation?

* Any tips for building a small, ethical business professional wardrobe (especially natural fibers) without defaulting to fast fashion?

Also, what are the best ways to pass on synthetic clothing responsibly? I’d much rather it be used than sit in a landfill shedding microplastics, but I’m not sure what the most sustainable option is.
