Yes yes the classic bib and brace. Will they ever go out of style? The 70s saw a massive revival of this versatile piece of clothing. Easy & quick to put together no matter what season. I wear mine in the winter with a polo neck and tights. I personally am not a fan of the full length dungarees like the SS10 Ralph Lauren version.
I'm more accustomed to using the Alexa Chung take on the short-dungarees with a Breton style top. Many high street stores like Topshop and ASOS have takes on the dungarees but I purchased my beaut re-worked Calvin Klein dungarees from a vintage store - see if you can get them somewhere because they look trés chic with their CK buttons and stamp.
