Peekaboo lace is very fashionable these days. Both former "Hills" and "City" starlets have been wearing the delicate fabric up and down the red carpet, and we've definitely taken notice.
Kristin Cavallari recently went for the gusto in a revealing long-sleeved dress, while her old costar Lo Bosworth added just a touch of the style along her sleeves. Over in Manhattan, Olivia Palermo rocked a lace frock with ruffles along the trim and Whitney Port donned a chic and contemporary number at the VH1 Divas event.
Check out the photo of these fashion-forward girls, then let us know who you think looked the best in sheer lace!

Both girls were spotted wearing this floral printed mini-dress by Stella McCartney, but who wore it best?
30 Rock actress Jane Krakowski wore the dress to an event in New York City. She added a black clutch, black strappy heels and curled hair to this look.
Olivia Palermo wore the same dress to The Romantics after-party. She paired it with black stilettos, a purple statement clutch and sleek straight hair.

Imagine wearing the same dress on the same day?
Not only were both Stephanie Pratt and Denise Richards spotted in the same frock, but they were both wearing it on the same day and were dangerously close to being in the same place!
Denise was the first to wear the black and gray strapless Bebe get-up at the Style360Bebe spring/summer 2011 fashion show on Sept. 14 in NYC. Later that night, Stephanie turned up in the same dress at the Style360 Bebe afterparty at the Griffin on the very same night! It’s a good thing Steph didn’t also attend the show, or there would have been a major fashion mishap!
Denise accessorized the short frock with some bangles and long necklaces, and a pair of black peep-toe pumps. Stephanie kept the look more simple, adding only a wide black belt to complete the look. While I think both girls pulled off the look beautifully, I like the way Stephanie kept the accessories low-key. Although Denise looked great, I also think this dress definitely needed a belt – and Stephanie’s accented her waist so well!

Roxy Olin and Kristin Cavallari both attended the Jill Stuart spring 2011 fashion show this morning in New York. And, OH NO, they both wore the same dress to the same fashion show! Maybe some people didn't catch it (surely the Jill Stuart publicists who gave them the dresses didn't), but we did. Even though the dresses are slightly different — Roxy Olin wore black and Kristin Cavallari wore purple — they are the same Jill Stuart strapless dress with a sweetheart neckline and pattern. These two even shared the same bright red lips! Only the accessories set them apart; Kristin wore red shoes and carried a furry chainlink bag, and Roxy Olin wore black sandals with a leopard-print clutch. They book look great but who wore it better?

The combination of this Heartloom Luna top and Kennedy shorts looks great on both girls, but who do you think wore it better?

Whoever said stay away from horizontal stripes wasn't speaking to this trio.
Our friends at Stylelist point out that this French Connection black and white horizontal-striped dress has made the rounds among the California starlets, starting with Olivia Wilde (left), who wore it to a French Connection store event back in February.
The 'House' star, recently voted sexiest actress of 2010 by Victoria Secret, kept eyes on the stripes with natural makeup and untouched hair.
Blonde reality stars Paris Hilton and Stephanie Pratt mimicked Wilde's simple but chic style by dressing up the casual t-shirt dress with sexy black pumps and super straight locks.
Paris added extra accessories to her look -- as she always does -- with statement hoops, black tights, headband, clutch and even black nails.
All three starlets rocked this tight t-shirt frock, but who wore it better?

Lil Kim Carmen Electra, and Stephanie Pratt all wore the same dress this week (well, Stephanie's is really close), but they look radically different from each other. Who looks best?
R&B star Lil Kim wore hers while celebrating her 34th birthday and creating a concoction at Millions of Milkshakes in West Hollywood on Sunday...
Carmen wore an identical dress while hosting an evening at Crown Nightclub at the Rio Hotel and Casino in Las Vegas on the same day...
And Hills star Stephanie wore hers Tuesday night at the series wrap up party in L.A.
