A Closet Staple
"OZMA knows how to make the perfectly oversized button up shirt and has ruined me for all others. The organic poplin is crispy without being stiff and still drapes nicely. I can tell this one is going to be with me for many years."

"OZMA knows how to make the perfectly oversized button up shirt and has ruined me for all others. The organic poplin is crispy without being stiff and still drapes nicely. I can tell this one is going to be with me for many years."
"I’m so glad this is the color of summer. This is my second poplin Marcie and I wear them constantly, perfectly oversized, stellar quality"
"Was hesitant because it's not an inexpensive shirt - but was SO happy with this purchase when it came in. Worth every penny. This is a perfect shade of butter yellow - well-made - I'll wear this every day."
"Incredibly breathable for hot summer days and very flattering. This shirt has become my daily go-to. Love it."
