Is anything?
Seriously.
I got a 997 as my first and since I've got pretty big tumors, it didn't do much until I double it up and even then, I couldn't wear even a button up without it looking freakish. I got a tritop from someone on here (Can't remember who but whoever you are, I owe you like you wouldn't believe) and it made a huge difference, especially layered with that 997.
Now I'm wondering, though, is there anything better than that tri-top? It works good, it works damn good, but I've still got weird lumpybits (collarboneboobs, really) that I'd like to get rid of somehow. Has anyone heard of or used one that works better? For reference I'm pretty hefty (270 last time I checked, 40-something D).
