Montce
A South Florida native, Alexandra Grief used her creativity and ingenuity to turn her side hustle into an international brand. With few resources, she started making swimwear in 2009 from her Fort Lauderdale apartment, where friends and customers stopped by for a curated, custom swimwear look that was made to order.
Quality fabrics, nostalgic prints, and advanced construction details make each bikini stand out, and extensive fit testing and quality control ensures that they're both flattering and comfortable. This effortless blend of style and substance, combined with an obsessive focus on fit, is what sets Montce apart — and why their customers only shop Montce once they’ve tried on the brand.
