Alright, I know this topic has been covered before, but I searched and searched and didn't find a thread that exactly answered my question.

I've seen a few EO jerseys on closeout here and there that I'm tempted to buy. I have never seen EO in person and am trying to figure out what to do in terms of sizing. Seems some folks think you need to size up, while some folks think it runs true...

Can those of you with EO experience help me? I'm looking at short sleeve jerseys. I'm 5'6", 33" chest, 26" waist, wear a 34A bra (so very small bust), usually a size 4. In terms of the size chart, I'm well within small territory on the bust measurement but borderline small-medium on waist measurement and probably a medium on hip measurement.

I normally wear a small -- in Gore, Shebeest, PI, etc. I also wear a size small in pre-2008 Castelli jerseys -- many people say to size up in Castelli (before they changed the sizing this year), but if I sized up, they'd be too big on me. I suspect this is partly because I have a small chest, and partly because I like a snug fit.

So, given all of this, do I go small or medium with EO?

Thanks!
