OP here...thanks for all the suggestions. Exercise is running and general working out in classes.
Has anyone tried 'Sweaty Betty' tops? Sold at Nordstrom and maybe other places?

I posted a similar question and here are the responses.

I ended buying from gap, under amour, and tjmaxx.

Checkout Outdoor Voices. Having a big sale right now on all of their good stuff.

Old Navy has the best quality.

Beyond Yoga

Zella at Nordstrom.

I really like Old Navy compression pants. They are squat proof. I prefer Gap for workout t-shirts.

What kinds of activities are you doing?

Honestly, I've had great success at Old Navy. TJ Maxx and Marshall's have some good things too, but be wary about see through bottoms, depending on what kinds of activities you're doing.

Not sure if this belongs in fashion, but what are some comfortable workout leggings, tees and tanks (other than crazy-priced lululemon!) that have worn well for you?

Thank you!
