Relationship between dress bust ease,wearing way and thickness of fabric

Dress bust ease is a key factor that affects clothing fit.This article analyzed the influencing factors and designing methods of clothing′s ease.In the experiment underwear,sweater and coat with different thicknesses were grouped into different combinations for different wearing ways,and the bust data and fabric thickness at the same position were measured of each wearing way.The experimental data were analyzed using stepwise regression analysis method to study the quantity relationship between bust ease and gap,and thickness of underwear and thickness of coat under the conditions of coats with different styles.A mathematical model of the relationship between bust ease,thickness of coat and thickness of underwear when wearing underwear and sweater was developed.A linear formula between bust ease,bust variation when wearing underwear and sweater,and coat thickness under different fitness was worked out as well.
