Need a midi dress that is actually midi

Hello! I'm a curvy/ plus size petite and I am looking for a midi dress that is work appropriate. The issue that I'm running into is that regular stores just don't have very many petite friendly pieces so I end up looking like I'm wearing maxi dresses to work (which isn't the vibe I'm going for). Any tips on where I can snag a nice dress or two before the summer heat kicks off?
