Preserve bikini details from a template or reference image

Preserve Swimwear Details from Templates & References

Choose from 9 bikini templates or upload a flat-lay, ghost mannequin, or model-worn reference. Our AI bikini image generator uses the garment as a guide for its cut, fabric texture, stitching, straps, and hardware, adapting the look to your photo. Preview the details together before choosing a result, or explore other outfits with the AI clothes changer.

Keep Your Identity, Skin Tone & Original Pose

Your swimwear can change while your portrait stays recognizably yours. This AI bikini photo generator focuses on your facial features, original skin tone, and pose, with attention to natural proportions and skin texture. Start with a clear photo where the outfit area is visible, then check hands, joints, and straps in the preview before saving your favorite look.
Blend swimwear highlights with the original outdoor scene

Swimwear That Belongs in Your Original Scene

Keep the atmosphere of your beach, poolside, or garden photo. PrettyUp's AI swimwear edits adapt clothing highlights, folds, and shadows to the original setting, helping the new outfit sit naturally within the scene. A sunlit starting photo gives you a bright vacation look, while soft shade creates a gentler mood. Choose a source image with the setting you want to keep.
Refine facial details, proportions, skin tone, and lighting

Refine Face, Body, Skin Tone & 3D Lighting

After your bikini try on, fine-tune the portrait on your terms. Use the face editor for facial touch-ups, adjust skin tone, or refine proportions with the body editor. From curvy and athletic figures to petite proportions, use sliders to choose the adjustments you want. Finish with 3D relighting to add depth and balance the portrait's highlights and shadows.

Reviews From PrettyUp's AI Bikini Generator

See how vacationers, creators, and shoppers use PrettyUp to test swimwear styles, preview custom designs, and find their best look with confidence.
★★★★★
"I wanted to compare bikini styles before a beach trip. Trying a few templates on the same photo made it easier to see which colors and cuts I liked. It was a useful starting point for my vacation wardrobe."
Emily Carter
★★★★★
"I already had a specific bikini in mind, so I uploaded its product photo as a reference. Being able to preview that design on my own picture was much more useful to me than getting a random swimwear look."
Sophie Bennett
★★★★
"The templates made it easy to get started without writing a prompt. I tried a couple of looks and picked the one that suited my photo best. A clear picture with my arms out of the way gave me a better preview."
Olivia Reed
★★★★★
"I used an existing poolside photo to try a different bikini for a summer post. Keeping the same setting helped the new look feel consistent with the rest of my photos, and the watermark-free download was handy."
Chloe Morgan
★★★★
"I run a small swimwear shop and wanted to explore a new style on an existing model photo. Uploading the bikini reference gave me a helpful preview. I still checked the straps and fabric details against the actual item."
Rachel Brooks
★★★★★
"I was worried a bikini edit would make me look like someone else. The preview still felt like me, and I could make small lighting adjustments afterward. I liked being able to finish the look without changing the whole photo."
