Quick question. Are you the same size on top and bottom?
Most of us aren't. And yet swimwear gets sold as one set, one size, take it or leave it. So you end up choosing: buy for your top and put up with a bottom that digs in, or buy for your bottom and spend the day pulling your top back into place.
You've done it. We've all done it. It's a rubbish choice and there's no reason for it.
So we stopped selling sets that way
Every tüsea bikini is two sizes, picked separately. Choose your top size, choose your bottom size, mix them however you like. Needing a small top and a medium bottom isn't a special request. That's just a body.
And now it goes further. Buy the top on its own for $99, the bottom on its own for $89, or the pair for $188. Mix sizes, mix colours, or skip the half you don't need. None of it costs extra, because none of it should.

If you're not sure, start with the Icon
This is the one we'd point you to first if you're hovering between sizes, because the Icon top has fully adjustable ties. Tighten them up when you want the support, loosen them off when you don't. It moves with you instead of making you commit on day one.
The bottom sits mid-rise with a split-side leg, so it sits on the hip rather than cutting across it. If you've been burned before by ordering swim online, this is the forgiving one. Start here, learn your sizes, go from there.

Picking your two sizes
Do the bottom first. It's the fussier of the two. Measure the widest part of your hip, check it against the chart, and if you land between sizes go up. A bottom that sits comfortably always looks better than one that's slightly too small, no matter how it looked in the mirror on day one.
Then the top. Here's where people trip up: they size by bra cup out of habit. Swim tops don't work like bras. What matters is your underbust measurement and how much support the style is actually built to give. A thin triangle tie will move with you. A thicker strap will hold more and stay put.
If you've got more to hold, look at the Rush II. Thicker tie straps, a clasp at the end of each one, and enough structure that you're not rearranging yourself every twenty minutes.
Still stuck? Order both
Genuinely. Get the two sizes you're torn between and send back whichever loses. Returns are free for 30 days on full-price orders, and that exists for exactly this reason.
Nobody can tell how a bottom will sit from a photo. We'd rather you worked it out wearing the thing than squinting at a size chart at 11pm.
Why it's worth the faff
A bikini that fits properly just disappears. You stop adjusting the ties, stop tugging the back down, stop having that low-level argument with your own swimwear that quietly ruins a good day.
That's all we're after here. Not a feature for the label. Just the difference between wearing something and managing it.
Enjoy responsibly.
