How much would medium size angle wings on your lower sholders cost?

A goat or two in certain Pacific Islands... to big bucks in Manhattan. Expect to shell out serious bucks if you want Kat Von D to do them in LA.

It all depends on where this is and the skill and experience of the tattoo artist. Some command high prices.

Do you mean angel wings? Smoothy is correct -- it varies. Call or visit some artists in your area to find out and compare prices (and expertise). Sketch what you want or Google to find images that might be close to what you want.
