Code-Switching Cognates

A friend of mine bought a jacket that had small belts on the shoulders that have very little function to my knowledge outside of holding one's beret. When I first saw it, I said something along the lines of the following:

...and you even have a place to put your beret.
[ænd.ju.ivən.hæv.ə.pʰleʲs.tu.pʰʊt.jɚ.bʌ'ɹɛt]

...oh I mean beret.
[oʷ.aʲ.min.bɚ'eʲ]

Which wasn't an example of my incompetence, but rather one that stems from the fact that I almost never say the word BERET. When I was younger, however, I had a lot of occasion to say баретка [ba'rɛtka], so I guess I just kind of went to the default form in my head, even though I was using English.
