So I bought a basic white long-sleeve tee that's kind of sheer. I was talking to the shop owner (who's Swedish and also a clothing designer) about what to wear under it. She said she'd wear it with a black bra showing through (like I had on when I was trying it on).

Is this a fashion/Euro thing, about bras showing? For example, Europeans seem to be more OK with bra strap peeking out under tanks/camis than people in the US.

So if I wore the tee with a black bra visible under it, would it look tacky? Does it depend on context? Or what if I wore a black Second Base half-cami?

Yay -- If it looks like you're showing your bra on purpose, go for it!
Nay -- That looks really tacky.

P.S. Sorry if I'm stereotyping here -- just trying to figure out if there's a cultural/regional thing going on!

ETA: Here's the tee:
