The advice is quite valid in fact, and the transformation to the jeans and red blouse look is incredible! All of a sudden she looks very youthful, and long legged, take not that in all the after looks she is in heels and makeup, making the metamorphosis more noticeable. However I think the final pink dress is too tight in the bottom area, and it looks good in the video only because she is wearing insanely tall heels, which are unrealistic in normal life, with regular shoe-wear her butt would be too low down. I also think her proportions were quite close to normal, so she was not such a prime candidate to demonstrate the long torso/short leg situation. However it is all valid advice.
