Sheer, silk, and sexiness.

This week saw an array of trend-setting styles donned across town, as multiple celebrity parties — including Los Angeles’ InStyle Summer Soiree and The Songbirlds’ Miss Me album release party — made room for fun fashion choices.

Of course, the summer weather also allows for eclectic new style ideas.

Celebs such as Hunger Gamers actress Jennifer Lawrence got all glammed up for the red carpet — and looked stunning — but others simply failed at their attempts.

Which major pop star did not have much fashion success this week?

Mother Monster, musician Lady Gaga, is known for her eccentric ensembles. Though some have been ridiculously amazing in the past, Celebuzz was more in shock than in awe about her big, furry pink jacket this week.
