Underworks 997 vs. 993 - what's the diff?

[Hooty_McBoob]

wondering what the difference is between the 997 and the 993.

I ordered up the 997, and maybe it was just too small for my body (I have a 43.5" chest, ordered the large which is good to 44" they say) - but it's tight as hell, and is cutting into my armpits, and is very tight on my stomach even though I don't have a gut at all.

Now, the 993 - would this be a better solution?

I have pseudo gyne, just a little fat I wanted flattened out. The 997 works AMAZING, but it is uncomfortable to wear...

Thanks for your advice.
