Perfection! We are absolutely in love. Out of the four products we have from Fernleigh Avenue the bikini is the definite favourite. From fit and fabric to the colour and overall vibe - we highly recommend!!
Beautiful cossie, quality is outstanding, my granddaughter is getting plenty of comments of how stunning she looks in it.
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! 🌟
The design is a good compromise of sunsafe, with the style being a little grown up but with good coverage. The quality is great and lined so there’s no risk of being see through when wet. My 9yo finds the clasp a little tricky, but has found a way to put it on without undoing it.
Stunning! Great coverage, perfect for kids who want to feel a little more mature, and still has the fun of an exposed back. Beautiful fabric, perfect fit and an overall a product I will buy again (after already purchasing 4!!) and recommend highly - worth it in every aspect.
Beautiful. Great quality. Love them. Just like the pictures. I just needed to take in the bottom strap, but that was easily done.
Beautiful. Just like the picture. Beautiful pattern. Great quality. Generous sizing, I probably could have gone down a size.
This is my daughters 3rd set of swimming togs that she has had over the years, they wear well and we love all the different patterns.
Lovely design and made well, as pictured they provide a great in-between option for my girls that I am also comfortable with. Great support from the owner when needed.
Beautiful swimmers. True to size. Great quality
My 10 year old loves this swimsuit. Great for squad and also just hanging with friends. I have lost count of the amount of people that have asked where the swimsuit is from!
These swimmers are really cute. The design is the right amount of cool and age appropriate! and the construction and material is really high quality. I would definitely recommend <3
Bought for my twin granddaughters for Xmas. Loved everything about them the colour the style the quality would not hesitate to purchase again.
Fit is good. I followed the size of her clothes rather than the size chart. They fit firmly. Colour is not as vibrant as the photos but it’s still a great swimsuit
I was so impressed with the first order, that I had to order again. The timeframe in which I received this package was amazing and I was kept up-to-date with its whereabouts.
Thank you Amy, I have recommended your business to all of my friends 🧡
Been looking for cute cossies for the girls for ages that fit well and provide enough comfortable cover. Might have to grab some in women's sizes honestly!
Super cute and comfortable. My daughter loves them!!
My daughter absolutely loves her new cossies and getting to show them off to her friends at Swim Scheme at school this week.
My tween and I absolutely love these swimmers! Great quality and built in light breast pads provide my tween with confidence!
My tween and I absolutely love these swimmers! The are great quality and beautiful designs. Fast delivery with a beautiful personalised message.
Girls absolutely love them! So cute and stylish
Nothing i didn't dislike, they were amazing
My youngest absolutely loved her new swimsuit and was so excited to wear it to Swim scheme this week!
Im very disappointed that the colour of my product is no where near as vibrant as advertised.
My daughter loves the design and the detail of the back of the suit and perfect for her squad swimming in summer . We did go up a size to 12 so it s a bit big but she has plenty of room to grow into. We will be purchasing the separate set for summer.
