Lanky (tall and thin) figure
This is a ideal figure. They are suitable a long hair but not to coiled hair or very short hair.
There is no good to wear a long straight wig/weft/hair extension, as well as wave kind. For them, they should choose layered short wig/weft/hair extension.
They should pick a simple concise wig, not a gaudy one.
