I'd like to translate the sentence "We need sunburn cream, bath towels and such."
Wir werden heute an den Strand fahren. Was brauchen wir fürs Sonnenliegen?
Wir brauchen Sonnebrand-Creme, Badetücher und oder so.

The most colloquial way is the one suggested in the other answer
... und so (was).
But there are several other versions that are more suitable for print.
... und solcherlei Dinge.
A bit overcomplicated, might work in novels or texts that make use of all the language has to offer. I can see that in a comedic text for instance.
... und dererlei Dinge.
Same as above but even more high brow and it doesn't have the least bit of a wink to it (solcherlei has). I can see that in literature.
... und dergleichen.
That is maybe the most neutral choice for print. It is not as mundane as und so but it lacks the "ornamentiness" of the other two.
(Being German) I can say that "und solcherlei" is definitely wrong!
Common idioms are "und so" or "und sowas" as well as the abbreviations "etc." and "usw." (the latter means "und so weiter").
A slang/sloppy version could also be:
"Wir brauchen Sonnencreme, Badetücher und so'n Kram" (or "... und so'n Zeug").
"... und dergleichen" is neutral and could be used in written text, while still being OK for direct speech.
