Customer Reviews
Reliable for swimwear
This is my third purchase from Costumiss. I got a Costume intero this time, and it was just as good as the Bikini a triangolo I bought last year. Shipping took about a week to get to me in Florida, which is standard for them. Their sizing is consistent, which makes reordering easy. I always check their new styles because I know the quality will be there. It's a solid choice for swimwear.
Good bikini, fast shipping
I ordered a Bikini Brasiliana. It arrived in about 6 days, which was quicker than I expected. The fabric felt good, definitely South American style like they said. Fit was true to size.
Loved my custom bachelorette swimsuits!
We got custom 'Costumi personalizzati addio al nubilato' for my sister's bachelorette party, and they were perfect! The whole group loved them. The customization process was easy, and they showed up on time for the trip. Everyone kept asking where we got them. I'm already planning my next purchase for a Kimono da spiaggia. You should really try them!
