FAQs



We’re so glad you asked…

We love receiving your questions about Sébastien swimwear. And it seems lots of you are wondering the same things – so quench your curiosity, and dive into our FAQs…


What if my order doesn’t fit?

No problem. We offer free exchanges and easy returns within 14 days of purchase. Find out more about our returns policy here.


What if I’m between sizes?

First of all, take a look at the fit details on the product page. Here, you can see how tall the model is and what size she’s wearing, plus whether the style runs true to size. If a style runs slightly small, we’d advise going one up from your usual size. We’re also in the process of re-cutting some of our swimsuits with added torso length, so if you’re a leggy girl, look out for our updated fits coming soon. If in doubt, send us an email at onlineorders@thisissebastien.com.


I’m unsure what style would be best for my body type. Can you help?

We’re passionate about making our customers feel confident and beautiful on the beach. For help finding the best style for your shape, drop us a line at onlineorders@thisissebastien.com


Does your swimwear come with padding or inbuilt cups?

Our swimsuits aren’t padded and don’t have structured cups. We know this can be a worry for those of you with enviable curves, so that’s why – in most styles – we use specialised, technical fabrics that sculpt the body and offer extra support (we’ve tested them rigorously to make sure). Check the individual product page details to see which fabric we’ve used.


The style I like is out of stock, can I still get it?
Yes and no. We don't do restocks often, we try to keep our quantities limited and want to avoid over producing, but it can happen that we'll have more units in stock but we just haven't uploaded yet. Feel free to ask!
