I am very skinny, i wear xs size and under 100lbs

I bought 3 swimsuits from mocobling and this one doesnt stretch enough to wear it. I thought i got a defective product and reported but was told that it is normal like that. Well, i don’t know how other ppl can wear this. Other 2 swimsuits are stretchable enough and i loved it but this one… so i dont recommend to buy this product if you dont want to waste your money.
