Quant, one thing all these designers and their gowns have in common is the cutting edge factor. You see, retro inspired means just that: something about the gown evokes yesteryear only there’s that unmistakable twist of contemporary thrown in for the here and now bride.
de la Renta above is from no era in particular but the way it's accessorized brings to mind the 20s with the cloche hat, 30s with the gown and gloves. Looks like something that might have been worn to the once popular daytime social.
To me this is another look encompassing a few eras. The gown above definitely looks 1930s, her hair 90s and the tiara 60s.
