Thanks for the help everyone! So far I'm not seeing what I want, so it's probably on me to compromise. I was spoiled for choice for many years so I'll have to work on changing.
I should have listed "nothing that takes a special bra" on my requirements list, so that Athleta top, while cute, is a no for me. I also don't think it would flatter anyone busty.
Joy, consignment did occur to me last night as a good place to find what is no longer in style. But...can't dance ballroom in a straight skirt!
Suntiger, I don't like to practice or go to coaching in any kind of skirt because then the issue becomes about not being able to wear comp heels for that long but feeling like my practice shoes and socks look ridiculous with a skirt. That's why I settled on dance pants and keeping all the fun on top.
I will keep looking, maybe attempt consignment and hope more sleeveless options show up closer to actual summer. Thanks for the help.
