Here's a good rule of thumb: if they can't make it look good on the model, you can't make it look good on you. On the website, the vest is wrinkled half to hell, the hat is drooping, and that lace looks very itchy. I can't even tell which character it's meant to evoke. I'd say don't buy it. If you're not trying to replicate a specific character's look, go to a thrift shop and find a shirt with poofy sleeves. You have a bunch of options for bottoms if you're just trying to look a bit piratical- a full skirt, long trousers with boots, shorts or capris with sandals, et cetera. Tie a colorful scarf around your waist, wear a bunch of costume jewelry, and you're good to go. If you find a waistcoat of some kind, so much the better.
