I have tried many and my favorites are those made by Jodie 
www.sissyangelwear.com She is also on here as LuvMySissy.  
Jodie uses the BEST velcro and I havent had my boy wiggle out of her belly bands. I have ordered other items from vendors and the velcro is very weak. She also will line them with satin. I cant say enough wonderful things about Jodie. She is the best!  
Shoot her a PM, she has great prices too!!
