Fabric & Construction Details

Fabric & Construction Details

We craft the Mossimo romper from a carefully balanced cotton-polyester blend that delivers softness with just enough structure to hold its shape through repeated wear. The fabric blend provides natural breathability while the polyester content reduces wrinkles and speeds up drying time after washing.

Double-stitched seams reinforce high-stress areas like the waist and inseam, ensuring durability through countless summer adventures. The elastic waistband sits comfortably at your natural waist and includes a removable fabric tie that lets you adjust the fit or create a more defined silhouette.


Sizing & Fit Guide

Sizing & Fit Guide

The Mossimo romper runs true to size with a relaxed, forgiving fit designed to flatter a range of body types. We recommend ordering your usual size for the intended loose, comfortable silhouette.

Size Chart Reference

Small fits sizes 2-4, Medium fits 6-8, Large fits 10-12, and X-Large accommodates sizes 14-16. The elastic waistband provides about two inches of stretch in either direction, while the adjustable tie allows you to customize the fit at your natural waist.


Styling & Versatility

Styling & Versatility

We designed this mossimo romper as a foundation piece you can dress up or down depending on your plans. Pair it with sneakers and a denim jacket for casual daytime looks, or add strappy sandals and statement jewelry for evening occasions.

The neutral color options work beautifully layered under lightweight cardigans or women’s blouses for transitional weather, while printed versions make a statement on their own. The functional side pockets eliminate the need for a purse during quick trips, holding your phone, cards, and keys securely.

Exceeded my expectations
Honestly didn’t expect to love this as much as I do. The fabric feels more expensive than the price suggests, and the fit is incredibly comfortable without looking sloppy. I’ve gotten so many compliments wearing this.

Perfect summer staple piece
I wear this romper at least twice a week during summer. It’s cool enough for hot days, easy to dress up or down, and the pockets are genuinely useful. Already planning to buy it in another color.
