I think about this, always. I work out a lot, but refuse to look lululemon-y. It’s expensive and off-brand for me.

Go to somewhere like Modell’s or Sports Authority. Target used to be a safe bet, but even they’ve recently embraced “athleisure” a bit too dearly.

Wicking fabric is nice for shirts, and you can get it cheaply at one of the chain stores. I go for a basketball-like short, one that goes at least to mid-thigh.

I find I have a harder time not focusing on looking Other at the gym than I do finding clothes that work and aren’t hella trendy. The gym has almost become like weddings: a place where people perform their performiest of genders. Good luck!
