Love the fabric & fit of this beautiful skirt., wish I’d purchased it sooner. It’s perfect to wear with a bump & I’m sure it will be just as comfy once bub is born.
Very comfortable and fits well.
Fits perfectly. I love the style
This dress is so beautiful. You can really tell how much time and effort has been put into every single detail. From the zipper matching perfectly (and zipping freely with no annoying jamming like many dresses do!) to the lovely soft lining. I can imagine this dress to be the kind you pack for a weekend away knowing it can be worn to anything - shopping, dinners, weddings, anywhere! I can't wait to see how it looks in Autumn with a scarf! Be one of the lucky ones to own one of these gorgeous dresses while you can!
Absolutely ❤ my Betty dress!
Thanks Cousin Billie.
The most exquisitely packaged online purchase I have ever made! So much attention to detail, I fell in love! It fits and feels perfect. Very happy xx
Beautiful colours, very versatile. Quality fabric. Thank you x
So excited to receive my first (& hopefully not last) design from cousin.billie. The packaging is A class. The skirt is beyond. Beautifully made and gorgeously fun! My Florida friends were most envious of this Awesome All Australian skirt. I got so many compliments. Thank you Cousin Billie. You’re the best.
A beautiful style & quality skirt! Love it💕
Im in love with this skirt. Such beautiful soft colours . I bought a bigger size and it sits on my hips so is the perfect knee length.for me. My daughter asked if it was hers as she loves pom poms hehe.. It was delivered so beautifully too, made me feel soo special. Thanks heaps Cousin Bille
Absolutely in love with my first purchase! A very fun, comfortable and gorgeous skirt that I’ll be getting many wears out of. Thank you Cousin Billie!!
Amazing, so soft and comfortable. Even though the skirt is linen, I felt like I could move freely in it and it was stretchy enough. The colour and pompoms are the bomb and I just love everything about this skirt. The packaging is next level amazing!!!! Felt like a total A lister getting a personal letter, extra little things like soaps and recipes. Honeslty love everything about this label and the lovely lady behind it is the bees knees being so accommodating when I make silly mistakes ordering wrong sizes. <3 xx
- Proud owner of two beautiful designed and thought-out Cousin Billie skirts.
I love my new pom pom skirt. It is so fun but still practical and easy to wear! Cannot wait for summer for lots of reasons, to wear this skirt being one of them! :) Thanks Cousin Billie!
This top is one of my favourite purchases. The cut and style is very flattering & the ruffles help balance my frame when wearing jeans.
I definitely need in every colour. I got the white colour & it's going to be very popular this season
This piece is just gorgeous. I wore it for the first time on the weekend & received so many compliments on how timeless I looked.
I'm so pleased with this dress & will be ordering more.
These are beautiful tops. I got the white and the navy. They sit nicely, and move with you. They are not restrictive at all, The frills make them special. I've got them packed for our holiday already!
The whole shopping experience was lovely. Thank you Cousin Billie!
I absolutely LOVE this top. It is comfy and I'm looking forward to not having to wear a singlet top underneath, making it a perfect top for a summer's day or one I can layer with in the cooler months.
I only wish I'd not waited so long to purchase this as the other colours have been snatched up. It's a top I'd love in multiple colours.
I'm going to feel good giving this voucher away. It looks so professional and I love the sticker that came with it to add to the envelope.
I love my new Veronica pencil skirt. It fits so beautifully, and I always get compliments when I wear it.
Love this skirt. The perfect length and fit and colours are exactly as pictured. Thank you
Siuch a lovely fabric,it will be perfect for travelling. I would love it in more colours. ❤️
The print, the colours, the zip detail, the fit, the length, not to mention the quality - I think I’ve found my perfect skirt!
Absolutely love my new dress. Such a flattering fit. The material is stunning and hangs so nicely. Can't wait to wear it!
Such a super cute little skirt! I adore it’s feminine lines and just love how versatile it is. There are no flaws, it’s very well made and is comfortable to wear. A valued addition to my wardrobe.
I have this tshirt in Navy and I really love it! It's extremely comfy, soft and easy to match with other skirts. The sleeves are great - can be a casual/dressy outfit. It doesn't really crease either - a huge plus for someone who hates ironing like me!
Bought this as a present for a friend - she loved it! Material is light and summery but still a quality covering. Love the pattern & fit.
I love the sleeve detail and fit of this top! It can be worn with really casual bottoms for a nice casual look, completely dressed up with a dress skirt or anything in between!
Skirt is beautiful. Quality of material and workmanship is amazing. Sizing is accurate. Thank you Cousin Billie!
I bought a white and an orange Ally Frilled Sleeve top and fell in love first wear. The fabric is beautiful and soft without being flimsy, the fit is super flattering without being too clingy and the frilled sleeves give that little bit of extra flair. I know they are going to be well worn this summer and would love to see it in more bright colours!!
This top is the perfect mix for when you want to be comfortable and dress prettily at the same time. The fabric feels really soft and delicate on the skin and is beautifully made. The frilled sleeves add such a nice element to the top and I love that they are just as soft as the rest of the top.
Such a beautifully made top and definitely an essential item in your wardrobe. Love the soft fabric and the fit. Can’t wait to see what other colours come out next season!
I purchased one top in navy and loved the style, fit and fabric so much that I ordered the other two colours Much classier then a normal tee shirt and can either be dressy or casual.
This beautiful top is made of material that is so soft to touch. The ruffled sleeves step the style up a notch from being a simple top to “simply elegant”. I can’t wait to see what other colours get introduced in this style.
Absolutely fell in love with this top as soon as I tried it on. The fit is perfect and the fabric so soft against your skin. The frilled sleeve detail makes a gorgeous addition to a staple wardrobe item, so you can dress it up or down!
I have been looking for a navy tee with some pretty detail for a while now with no luck. Finally I found one I love. Flattering fit and beautiful, soft fabric! Can't wait for summer so I can wear it!
