Hello, thanks for your support. :)
1. Yes, we can add 2 pockets (on the pants? 1 pocket on 1 side)) for you, just write down the request in the Remark box when you order it.
2. This is a polyester costume.
3. If you'd like to buy "custom size", please simply select the 'custom size'and fill up your exact body size, and our tailor will adjust the costume size to fit you. n_n
*Custom size costume doesn't charge extra cost, but the processing time will be longer than standard size costumes; for this costume in custom size, we need about extra 1-2 weeks to make it (excluding the shipping time).
