With the boys of Costello Tagliapietra! They can't not put a smile on your face :), Laskhmi tweeted.

The Costello Tagliapietra collection is sold at Barneys New York and select specialty boutiques worldwide. The brand is created by Bristol, Pa.-born Jeffery Costello and his partner, New York native Robert Tagliapietra. The brand premiered in Spring 2005 on the New York runway and won the Ecco Domani Fashion Foundation award that year.

Gorgeous ruching details and precise tailoring at Costello Tagliapietra made the pieces simply elegant. You want this! Twitter user OpeTheStylist wrote about about the duo's 2012 designs.
