What to know about Sid Mashburn

Sid Mashburn is an independent American menswear label and retailer founded in Atlanta in 2007 by Sid Mashburn, previously a designer at Ralph Lauren, J.Crew and Tommy Hilfiger. The house label centres on softly constructed suiting, oxford and camp-collar shirts, chinos and knitwear in a traditional Ivy-meets-Italian register. Its shops, opened in cities including Houston, Dallas, Washington, D.C. and Los Angeles, pair the in-house range with outside brands and full alterations, and sit beside the womenswear line Ann Mashburn.

How Sid Mashburn fits

Overall fit

slightly small

Shoppers generally describe Sid Mashburn's house label as cut on the trim, tailored side, so people used to American mall-brand sizing often end up going up one size while slimmer builds find it true to size.

Tip: If you're between sizes or want any layering room, take the larger size — most of the line is cut trim rather than generous.
