I am a true 27.

-Medium New York Flare sigs - runs a one size small IMO. A 27 was too tight at the upper thighs and hips for me.
-Caribbean Flare sigs - runs TTS. I have this in a 28, and they get baggy by the end of the day. They are my comfy/I-feel-like-shit-today jeans
-Brooklyn A's - runs one size small. I had this in a 27 and it was way too tight at the waist.
-Seville bootcut sigs - runs one size small/get rigid jeans size
-Milwaukee sigs - runs a bit small, but get usual size because it stretches
