Specification states both cotton and poliester - its definitely more of a poliester. The sizing is off - I got 18M which turned out to be really oddly short in the legs - like mid-calf.
I ordered this suit. As a result, a completely different suit and the size of a year is approximately. Contacted the seller, apologized, offered an exchange. In the end, the coupon was sent. The suit was kept.
