The question of the "Comfortable" height of the heels and length of the shirt. I have 2 points:
1st How many collages and sweaters I spent on chairs in school and universe - not to say. The budget for the collots had to be simply put into the monthly expenditure. I gave up and went over to the jeans. The shirt is up to your knees, only as long as you stand, and when you sit, it immediately strikes.
2nd I don't know who is comfortable with these 3-5 cm, but I can't run after the child for 4 cm, and it's hard to stand in the electric car, and with a quick walk, the legs turn. I look at my husband's shoes - heels not higher than 1.5 cm. In winter, it is quite thick, but the gap between the heels and fingers is insignificant. Like on my shoes: footwear - 3 cm, actually a heels +1 cm. We look at children's shoes: before school it is equally flat for both boys and girls. And on the teenage girl has already spread from quite flat to 5-7 cm. At the same time, the boys continue to walk on their heels at 0-2 cm.
