Just when we thought she retired her leggings for the season, Lilo brought 'em back last night when she attended Markus Klinko & Indrani's "ICONS" exhibit at the Pacific Design Center.

After showing off her infamous side boobies earlier that evening, Lindsay headed home around 7pm, changed into yet another outfit and left the house around 9pm. Lindsay and a pal arrived at the PDC around 10pm, and X17 photogs tell X17online that the duo left at 11:45pm and headed to Mickey D's and then Chateau Marmont.

Linds returned home around 12:30am, and even though she didn't go to bed immediately (she was busy tweeting online until 2am), this was a relatively calm night for the starlet - maybe she's starting to slow things down?
