The term "milkbaby" originally started as a nickname given to Cat Thordarson, the founder and designer of milkbaby bikini. The term referred to a healthy girl who looked like she "drank her milk", which inspired her to use the name and create milkbaby bikini.

From the beginning, Cat has been milkbaby's designer, pattern maker and manufacturer, while growing the brand with a grassroots approach. Her designs for milkbaby bikini have been featured in Sports Illustrated Swimsuit 2011-2018, which continues to challenge and push her as a designer as she creates new styles for the editors of the magazine. 


Cat believes every woman has a bikini body, so milkbaby has swimwear designed to look and feel amazing on all shapes and sizes.


Milkbaby creates bikinis, monokinis and one-piece swimsuits in a variety of innovative styles, designed to flatter a variety of body shapes.  Every piece is handmade with quality construction, to ensure durability and amazing fit.

Custom swimsuits are made-to-order by choosing style options from custom swimsuits and then selecting a fabric, which is cut to specific measurements. Appointments with the designer are available at the milkbaby studio, where clients can try on custom style options as well as browse through many one-of-a-kind samples, available for purchase.


Milkbaby bikini is sold on milkbabybikini.com, Amazon Handmade, Shoptiques.com, Etsy.com, Aftcra.com, as well as the Las Vegas design studio at 3885 S. Decatur Blvd #2010 LV, NV 89103.
