I wear a 27 in TR but what about R&R rebecca?

I always wear 24 in R&R and True Religion as well. keep in mind that if you want them tight, them they should be fairly tight when you first put them on, R&R stretches quite a bit!
 
thanks everyone for the advice. I actually ordered the 27 and im hoping they fit. I will update once they arrive in case someone does a search later on and needs help with the sizing of these jeans!
