May I be correct?

Click on the button that says "Declension of kostym" to find out.

You'll find it a lot more convenient and effective to use a site like wiktionary than asking the question here when you're unsure of word variants.

Would women's suits also use kostymer?

[Zmrzlina]

I think so.

What is the rule in plurals about -ar vs -er? It doesn't seem to follow the "en"/"ett" rule and I'm just guessing most of the time...is it just something you need to learn? Thanks!

Declension, usually. You can find some great info e.g. here: https://www.thelocal.se/blogs/theswedishteacher/2010/07/28/plural-endings/

Tack så mycket! So helpful!!

I really want this kostymer to relate to the English word customer! I see them related, as a person in a suit walks into a store to buy more suits! ;-)

[devalanteriel]

They're both from the same Latin root, yes.
