I wish I could have them all

This swimsuits are just amazing. There are no words to describe the empowerment and confidence you get when wearing Louswim. This is my second Fio because I just couldn't resist the discount. And now I'm on the verge of buying Tori. :) They are a bit pricey for my country standard (Croatia) but so worth it. Thank you Louise for creating these!


The colour is amazong the same as on the photos! Fits perfectly and perfect for the summer💕

Amazing swimsuit

This bikini set is amazing and truly fits my small boobs which gives me such a confidence boost! Lou has also been nothing but super nice and helpful with sizing and inquiries. Packaging is cute, the swim suit even better. Can’t wait to order again when there are new styles coming out 🥰

Got my confidence back

I had high hopes for this bikini because of all of the reviews, and I definitely lived up to them. The fact you can order different size top and bottom is perfect. The bikini fits so beautiful, I actually have boobs in it and there is no ugly gaping like with most regular bikinis. I hated going swimming because of it, but now I can’t wAit to go again! And the periwinkle color is so beautiful!
