Maternity clothes?!

Where is everyone buying their maternity clothes from? I'm having the worst time trying to find affordable clothing that doesn't damage easily. I mean I purchased a pair of shorts a month ago and the crotch already ripped!!😫 I thought the purpose of maternity clothes is to be able to with stand the growth of the baby inside your body?! I mean I'm 4 days shy of 30 weeks and I've only gained 10 pounds, so it's not like I'm rapidly gaining weight.  Please comment some recommendations on stores and websites. ☺️
