The BlueUni Guide

Where is BlueUni made?

Every BlueUni piece is thoughtfully designed in Southern California and produced in small batches using premium materials chosen for their softness, durability, and performance.

What sizes do you offer?

We currently offer sizes S, M, and L. Expanding our size range is one of our highest priorities, and extended sizing is planned as BlueUni continues to grow. If you’re between sizes or would like personalized guidance, we’re happy to help. Reach out through our Contact page or send us a message before ordering.

How should I choose my size?

Each style is designed with adjustable features and stretch fabrics to provide a flexible, flattering fit.

Visit our Size Guide for detailed measurements, or contact us if you’d like personalized sizing recommendations.

Can I mix and match sizes?

Yes. All BlueUni tops and bottoms are sold separately so you can create the combination that fits you best.

What makes BlueUni different?

BlueUni was built from years of living in swimwear.

Every detail has a purpose—from premium fabrics and supportive construction to hardware-free designs that move comfortably with you. Our goal is simple: create swimwear you’ll reach for season after season because it fits beautifully, feels incredible, and lasts.

Are your bikinis double lined?

Yes. Every BlueUni swimsuit is fully lined for comfort, coverage, and durability.

Will my swimsuit stretch out?

No. We use premium fabrics and high-recovery elastics designed to maintain their shape with proper care.

How do I care for my swimwear?

To help your swimsuit last for years:

  • Rinse with cool water after each wear.
  • Hand wash using a gentle detergent.
  • Lay flat to dry in the shade.
  • Avoid bleach, rough surfaces, and high heat.
How long will my order take to ship?

Orders typically ship within 2–5 business days.

Once shipped, delivery times vary by destination, but most U.S. orders arrive within 3–7 business days.

You’ll receive tracking information as soon as your order ships.

Do you ship internationally?

Yes. International shipping is available to select countries. Shipping rates and delivery estimates are calculated at checkout.

What is your exchange policy?

If your purchase isn’t quite right, eligible items may be exchanged for another style, size, or color, or returned for store credit.

Exchange requests must be submitted within 14 days of delivery, and all items must be returned unworn, unwashed, with tags and hygienic liners intact, and approved upon inspection.

Refunds to the original payment method are not offered.

Please visit our Returns Policy page for complete details.

Can I exchange bikini bottoms?

Yes.

To give customers greater confidence while shopping, bikini bottoms are eligible for exchange or store credit provided they are returned in brand-new, unworn condition with the hygienic liner intact and pass inspection upon arrival.

What if my item arrives damaged or incorrect?

Please contact us within 48 hours of delivery with your order number and photos of the item. We’ll make it right as quickly as possible.

Do you restock sold-out pieces?

Some colors and styles return, while others are produced as limited small-batch releases.

Join our email list or follow us on Instagram to be the first to hear about restocks and new collections.
