Amazing experience
I had an amazing experience with Design by Si! The delivery and pick-up were fast and super easy. I ordered the Britney pants, and to my surprise, they fit perfectly—something I’ve never experienced without needing alterations. Design by Si truly proved that it’s possible to find pants that fit just right straight out of the box. The prices are fair, and the quality is excellent. Highly recommend!

Wasn’t Sure at First, but So Glad I Bought Them!
Wasn’t Sure at First, but So Glad I Bought Them!”
I’m honestly so happy with my purchase! I bought the pants and the shoes, and I absolutely love both. The pants are amazing—the quality is really impressive, and they’re super stylish. Every time I wear them, my friends compliment me and say how beautiful I look. Everyone loves them! For the price, the quality is honestly better than I expected.
The shoes are also so cute and beautiful. Again, considering the price, the quality is really good. At first, I wasn’t sure if everything would be as nice as it looked, but I decided to trust it—and I’m really glad I did.
For now, I’ve only bought the pants and shoes, but I feel so good in them. I love everything about them—the quality, the style, the beauty, and the classy look. Definitely recommend!

Loved their quality & design
I’d been searching for a good bikini set for almost 4 weeks before summer started, and this was my first time ordering from Designbysi. Everything turned out exactly how I expected it to be! I absolutely loved the “Solveig Bikini” the quality and design were top notch. Plus, it was delivered super quickly!

Terrible quality
Shipped to Australia. Order 4 x knits. I opened two of the knits and the quality and sizing was so poor. Itchy and cheap knit. The sizing for XS was more like a large. So I immediately returned via post which cost me another $60AUD out of pocket. Don’t bother :(

Hi,
Thank you for your feedback. Lovely to hear that you're satisfied :)
As a little bonus info, we're currently in the process of implementing and testing a new size guide. The goal is to give a clearer overview of the different measurements across various styles, so hopefully we can help avoid situations where a style might run a bit small.
Wishing you a fantastic day :)
