Hmmm…I don’t know what “outrageously priced” means to you (or how the Victoria’s Secret bra you referenced fits), but have you tried looking for a convertible push-up bra?
Victoria’s Secret’s bras are pretty simple, and push-ups are really common now in both department stores and places like Aerie.
Edit: Or Frederick’s of Hollywood. Thanks VintageVal!
