English idiom or proverb equivalent for "if everybody is doing it, I will also do it"

Can somebody please help me by giving an English idiom or proverb equivalent for:

If everybody is doing it, I will also do it.


"When in Rome," short for "When in Rome, do as the Romans do," could work. It expresses the notion of doing what everyone else does, though it perhaps more justifies than describes such a situation.


The two phrases that spring to mind are "follow the crowd" and "jump on the bandwagon".

follow the crowd: to do what everyone else is doing; go along with the majority; do what most others are doing

I am an independent thinker. I could never just follow the crowd.
When in doubt, I follow the crowd. At least I don't stand out like a fool.

jump on the bandwagon: to support something that is popular

Publishers jumped on the CD-ROM bandwagon even though they didn't know if they could sell CD-ROMs.

Consider, go with the flow and follow the herd.

go with the flow: also, go with the tide. Move along with the prevailing forces, accept the prevailing trend, as in Rather than striking out in new directions, I tend to go with the flow, or Pat isn't particularly original; she just goes with the tide. The flow in the first and more colloquial term, which dates from the late 1900s, alludes to the ebb and flow of tides and probably gained currency because of its appealing rhyme.
