My new FAVORITE tanktop from Amazon! This one has a built in bra and I am obsessed with how it fits. I am wearing a size large in the tank. I would say it runs TTS but also wouldn't hurt to size down one to hold everything up in your chest area! SIZING: Tank: Large - runs TTS but could also size down for a tighter fit in the chest area Walmart Camo Zip-up: Large - runs TTS LTKootd LTKOver40 LTKMidsize
