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.
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

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!
