You are "lucky", in that both the 54 and 56cm frames can fit you without too extreme of measures. On the 56 you will look right by everyone who sees you. If a frame fits you, you will look right on it. On the 54 you may have to use a longer stem than really ideal. Maybe a bit more seatpost sticking up. Maybe the saddle pushed way back further than on the 56 frame. Maybe extra spacers to get the bars high enough because the 54 frame will have a shorter headtube and the bars will therefore be lower. If you add all these somewhat easy and normal modifications together, people looking at you on the bike may say "the bike is a little too small". Not extremely too small, but still too small. Doing one of these modifications to get the frame to fit, that is OK. But you may have to do all of them to get the slightly too small frame to fit.
