Creating girls bathers that offer the perfect balance of confidence, comfort and support.

That's why we've extended our range into Women's Sizes 6–12. Allowing older tweens and teens to continue wearing swimwear designed specifically for their changing bodies.
Crafted from premium eco-friendly fabric, these girls bathers are double layered for exceptional coverage and feature UPF 50+ sun protection and chlorine-resistant fabric.

Gorgeous products, and great customer service! I purchased three pairs of swimmers for three of my daughters, only one pair didn’t fit. I emailed customer service to ask about returning it and she sent me a postage label so I didn’t have to pay for postage! I was refunded as soon as they got the swimmers back.
We love the swimmers. They look so beautiful ❤️
This swimwear for my daughter’s is a game changer. Quality material, excellent design around fit and coverage, and the girls just love the look! It’s hard at times to satisfy a teenager and these suits do just that. Add in that the owner “Amy” cares about her product, and is amazing with her customers. We are repeat customers from the other side of the world in Canada.
Hi Steve,
Thank you so much for sharing your heartfelt story. We're truly touched to hear how our swimsuits have made such a positive difference for Sarah. Your kind words motivate me to keep designing with love and care. We look forward to welcoming you back soon!
Warm regards,
Amy
beautiful suit and fully lined top half which is great for girls. The fit is a tad small, I bought my daughter (typical 10/12) a size 12 and it fits great. The details are fantastic and she loves it. However the colors are a bit muted. The pink it not a hot pink like the pictures, nor is the blue. I was a bit disappointed in the colors but the overall suit is great.
Hi there! Thank you for your lovely feedback. We're glad your daughter loves the suit and that it fits well. We appreciate your note about the colors and will keep it in mind for future updates. Thanks for shopping with Fernleigh Avenue!
From the print to the style this swim suit covers all the bases ! We were poolside and had SO many compliments about the really cool detail of the back. It was also stretchy and easy to get on. Super cute suit
Hi Carlie! We're so glad you loved the Pippa Open Back Girls Swimwear and that it received so many compliments. Thanks for sharing your experience happy swimming! 🌟

Such a stunning colour, beautiful design and age appropriate for my 9 year old. Thank you
Such beautiful Bathers, perfect fit and coverage. My 9 year old loves them. Thank you, highly recommended
Beautiful swimwear, have a few different pieces for my 4 year old granddaughter now buying also for my 18 month old granddaughter. Always get comments when they are wearing them. Don't fade in chlorine like other swimwear and look gorgeous on and perfect fit
Hi Renee, thank you so much for your lovely review! We're thrilled to hear your granddaughters love the swimwear and that they hold up well in the pool. We appreciate your support and hope they continue to enjoy their swims! Best, Fernleigh Avenue
First you designed swimsuits that are truly amazing. We have purchased quite a few for my oldest daughter. Now I have to thank you once again, for producing the same beautiful suits, in sizes that my younger daughter can enjoy.
If you could have seen my younger daughter a year ago, with tears in her eyes when the suits I bought her didn’t fit. It saddened me but I told her we were all built different. Not something we can control. She is big boned. Not fat. It still was sad.
Then you mentioned you were considering larger sizes. I really hoped it would come to reality. Thank you Amy, for taking the chance on larger sizes. If you could have seen Sarah’s smile today when she tried on the two suits, and they fit her perfectly. She is only 15, and times are hard as a teen. Today, that was not even in her thoughts. She was above the world, feeling beautiful, with no concerns around fit. It’s a small win, one that the smile said everything.
I wish you the best and hope you continue your great work. We will be back for sure. Again thank you Amy. From Northern Canada! Steve

These swimmers are absolutely beautiful. My daughter is 13 and I ordered the size 6 ladies. They fit her perfectly she said she feels so comfortable. The cut of the pattern and the double lining is perfect for a fashionable cute but modest swimsuit.

Absolutely love these bikinis for my 10 year old! Not sure if it’s her body, but the bottom fits really well, and the top is loose enough for some growth! She loves it and feels confident and cute at the beach 💕
Hi Sarah, we're so happy to hear your daughter feels confident and loves her bikini! Thank you for sharing your lovely feedback. 😊
Amazing fit, my 9yr old is tall but has no bum so I love the high back of the bottom section. Brilliant quality. Love them!
The Lila Crop Tween Bikini is an absolute favorite!
As a trans woman, finding cute swimwear that fits well and makes me feel comfortable in my body can sometimes be a challenge, but the size 16 fits like a dream.
The quality is incredible, and the design is just gorgeous.
Beyond the amazing products, what makes Fernleigh Avenue so special is Amy's commitment to true inclusivity. Knowing that trans women are welcomed, seen, and celebrated here means everything. I couldn't recommend this brand more!
