This study provides references that can be applied to future suit design by analyzing the formative characteristics of modern men's and women's suits. Research on related literature and case studies were carried out simultaneously. A criterion for analyzing formative characteristics of suits was drawn up through an examination of past research. A total of 1,410 suit photographs that appeared in the U.S. edition of Vogue Magazine from 1985 to 2008 were analyzed in order to observe the formative characteristics of men's and women's suits. Research results showed that in the 1980s suits pursued a more comfortable and natural fit based on the original properties of simplicity, modernity, and practicality; in addition, women's suits had a tendency to use excessive shoulder pads due to the power-look influence. In the early 1990s exaggerated shoulders and boxy straight silhouettes were in fashion but towards the later years suit designs gradually started to fit the body and established a skinny versus slouch conflict. Women's suits gradually began to show more curvy body lines, and men's suits became more feminine on the surface in terms of color and material. In the 2000s suits have become more feminine and sensual than the 1990s, design focuses of both men's and women's suits moved to the waistline. Skinny and long styles became the ideal silhouette and differences between formative characteristics of the two genders decreased. Fashion elements of men's and women's suits are seen to have changed with a mutual intimate connection under the influence of a similar societal environment.

We observed 80 dense cores ($N(H_2)$ > $10^{22}cm^{-2}$) in the Orion molecular cloud complex which contains the Orion A (39 cores), B (26 cores), and ${\lambda}$ Orionis (15 cores) clouds. We investigate the behavior of the different molecular tracers and look for chemical variations of cores in the three clouds in order to systematically investigate the effects of stellar feedback. The most commonly detected molecular lines (with the detection rates higher than 50%) are $N_2H^+$, $HCO^+$, $H^{13}CO^+$, $C_2H$, HCN, and $H_2CO$. The detection rates of dense gas tracers, $N_2H^+$, $HCO^+$, $H^{13}CO^+$, and $C_2H$ show the lowest values in the ${\lambda}$ Orionis cloud. We find differences in the D/H ratio of $H_2CO$ and the $N_2H^+/HCO^+$ abundance ratios among the three clouds. Eight starless cores in the Orion A and B clouds exhibit high deuterium fractionations, larger than 0.10, while in the ${\lambda}$ Orionis cloud, no cores reveal the high ratio. These chemical properties could support that cores in the ${\lambda}$ Orionis cloud are affected by the photo-dissociation and external heating from the nearby H II region. An unexpected trend was found in the $[N_2H^+]/[HCO^+]$ ratio with a higher median value in the ${\lambda}$ Orionis cloud than in the Orion A/B clouds than; typically, the $[N_2H^+]/[HCO^+]$ ratio is lower in higher temperatures and lower column densities. This could be explained by a longer timescale in the prestellar stage in the ${\lambda}$ Orionis cloud, resulting in more abundant nitrogen-bearing molecules. In addition to these chemical differences, the kinematical difference was also found among the three clouds; the blue excess, which is an infall signature found in optically thick line profiles, is 0 in the ${\lambda}$ Orionis cloud while it is 0.11 and 0.16 in the Orion A and B clouds, respectively. This result could be another evidence of the negative feedback of active current star formation to the next generation of star formation.
