Underworks: which size?

[Farm Boy]

I need a new binder, as mine is wearing out.  According to Underworks' measuring guide I should get a size XS (my measurement is 29.5 for the Tri-top) but my current binder was given to me used and it's a size small.  It works well enough, as I'm hoping for peri surgery one day and don't want to compress my chest to death.  The problem is, a while back I got a used XS Tri-top that is much larger than the small, and it just hangs loosely on me like a shirt.  I've heard Underworks' sizing is weird and inconsistent, so I wondered if the large size difference was more likely to be factory related or binder life related, and whether I should order a small or an extra small.  What do you think?

XS: 28-30
S: 31-33

Also, has anyone tried any of their nude colored binders?

From memory I think double front sizes are an inch larger than the tritop's, and I have an XS double front and a second hand XS tritop.  The double front is much tighter than the tritop -- although both get me flat enough, I can normally pass not wearing either though. I think the sixe difference is probably due to them stretching out over time and not the factory.

The nude colours are fairly new so I dont know whether theyve been brought much

The 997 does run larger than the tri top. Beyond that, I really haven't seen inconsistent sizing. Order the small and if it doesn't work you can always send it back. They're pretty great about that stuff. If you measure on the larger end of XS, then it would probably be better to get the small.

Cool, thanks guys!
