Summer maternity clothes?

Favorite places to buy maternity shorts and other summer clothes? My first was born at the end of May but this one isn’t due until August. I have a nice wardrobe of business casual clothes (which I never wear now that I work from home), but I’ve got nothing for hotter days. I looked briefly online but $35 for a pair of shorts I’ll wear for maybe 3 months (last kid), seems ridiculous!

Where do you find decently priced summer maternity clothes with thrift stores not open?
