Candice Swanepoel, Victoria's Secret model, appears shockingly thin while promoting new swim line

Candice Swanepoel (l. in March 2010, r. Wednesday) is sporting an alarmingly tiny waist.

There's sexy skinny and then there's scary skinny.

Model Candice Swanepoel looked more like the latter Wednesday when she made an appearance to promote the new Victoria's Secret line of swimwear at the collection's launch event in West Hollywood.

 Swanepoel's itty-bitty bikini only highlighted her stick-figure legs and bony arms. The 22-year-old South African's waist was also shockingly thin.

Fellow models Alessandra Ambrosio and Adriana Lima, who flanked Swanepoel on either side while posing for pictures, also showed off skinny – yet more enviable – bodies. Ambrosio, however, has been criticized in the past for also appearing too thin.

Swanepoel seems to have lost a significant amount of weight since she appeared in ads for Victoria's Secret's Valentine's Day campaign, which began in January.
Also released in January was the Victoria's Secret 2011 Swim Catalog, which featured a slender, but seemingly healthier, Swanepoel on the cover.

She has posed nude in numerous magazine pictorials that often highlighted her small frame, but she now appears to be smaller than ever.

According to her modeling agency, IMG, Swanepoel is 5-feet-9 and a size 8 with 33-23-34 measurements – figures that seem unbelievably out of date.

Swanepoel's current body type seems to be a marked departure for the Victoria's Secret brand, which used to be known for featuring more curvaceous beauties like Tyra Banks.
