Ok, they can be really cute if they're shorts overalls and you pair them with a crop top and converse or vans. But I usually don't wear them. Overalls and chokers are the few old-fashioned trends I don't hate. I actually want a moon/sun charm choker!!
Back in the 90s they were legit cool and unusual. They look a bit hipster now. If that's your style, rock it. Generally speaking I'm a bit skeptical of anything hipster. Can look a bit artificial and bandwagon-y.
I love the second one, really cute (both the overall and the girl :) ) I'm not a fan of the light jeans color in the third picture. Actually the second one is the only one I like (love :D). The other ones either looks saggy or have an unappealing color.
Some girls look good in them. 2nd pic is ok but girls don't look much attractive in it, also depends upon if it suits on some girls body kind, but for me, I don't find girls attractive. So my opinion is don't go for it ;-)
Where I'm from only farmers wear them or people when they're gardening or painting a house or whatever. It's only recently they've become a fashion trend amongst younger teenagers. I don't particularly like them, only some people can rock them to me. However, if you like them go for it.
