Why I learn English

I began to intensively study English so that I would better understand my clients. I sew costumes for cosplay, corsets and costumes of fairies and elves. Here is my shop on etsy https://www.etsy.com/ru/shop/DuchessChest
I want to quickly and professionally respond to my clients. I want to improve the service I offer.

Well done - this was almost perfect. I have underlined three changes I would make.

You make gorgeous costumes too!
