  • Content: 80% polyamide, 20% elastane; Lining: 87% recycled nylon, 13% elastane
  • Care: Keep a good thing going by giving this swimsuit the care it deserves:
    • Using a small amount of mild detergent, gently hand wash in fresh, cool water — it’s better for your swimsuit and the environment. Steer clear of fabric softeners.
    • Rinse well after washing. Avoid wringing to prevent fibres from overstretching and breaking down.
    • Skip the dryer — and the greenhouse gas emissions. Instead, air dry your swimsuit by laying it flat.
    • Make sure your swimsuit is completely dry before storing or wearing.
    • Avoid contact with lotions, oils, bleach and rough surfaces. Also, avoid ironing.

Cheeky perfection
Well constructed bikini bottoms. Bright rose colour leans a little cooler than shown in photos. Matching matte coloured hardware gives it an elevated touch. Since this is a ruched tanga, stick with your usual Aritzia TNA size to avoid gaping. I have a 26” waist and 36” hips so size S fits perfectly.

So cute, would buy in other colours
These bottoms are SO flattering, and so cute. Some adjusting needed if you're going to swim in them, and make sure to tie the string extra tight on the side. Bought a size L and I'm usually a size 30 in jeans.

Skeptical but Love!
Was very skeptical of ordering these bottoms because I am not used to buying swim that is minimal coverage but actually impressed and keeping it! You can adjust it a bit by spreading the fabric to increase coverage and I do not find the back too revealing. Looks super cute and flattering and I appreciate how it is high waisted! I did size up but I have bigger hips compared to my waist.

Ladies, your man will drop his jaw when he sees you come out in these bottoms. They’re the perfect sexy ruched bottom. They do run a bit small, so size up.
