Seriously, now our tulle-filled heads are just spinning.

It's been the question among fashion insiders for months: Will bride-to-be Chelsea Clinton wear Vera Wang or Oscar de la Renta when she walks down the aisle to marry investment-banker fiancé Marc Mezvinsky on July 31 in Rhinebeck, N.Y.?

A friend told StyleList back in June that 30-year-old Clinton had a made-to-measure wedding dress in Vera Wang's workshop, confirming what we had speculated all along -- that the presidential progeny is opting for the epitome of classic American bridal.

That was until Sheryl Gay Stolberg, The New York TImes White House correspondent, told Ann Curry on the "Today Show" that the former first daughter had chosen an Oscar de la Renta gown. So, maybe we spoke too soon. Or not... The plot thickens.

WWD's Wednesday, July 28, cover features Chelsea Clinton, obscured by a large floppy hat (so much for going incognito!), arriving at Vera Wang's midtown showroom in New York City on July 27 to meet her Secretary of State mom, Hillary Rodham Clinton, who was already there.

Reportedly, Wang is doing the bridesmaids' dresses, the flower girls' dresses, as well as the all-important wedding dress. And supposedly Hillary and Chelsea have met with Wang five to 10 times over the last four months. OK. Settled. Score one for StyleList.

Not so fast. Hillary was also spotted paying a visit to Oscar de la Renta's Manhattan showroom earlier the same day. There are conflicting reports as to whether Chelsea accompanied her mother, but the duo has allegedly met with de la Renta numerous times of late.

And, after all, the designer -- who often dresses the former first lady, starting during her turn at the White House -- is reportedly close friends with the Clintons, as in the couple vacations at his Dominican Republic home.

The Clinton camp, in addition to Vera Wang and Oscar de la Renta spokespeople, declined comment to WWD.

So, will Chelsea Clinton wear both designers during her weekend wedding? Will just Hillary be wearing de la Renta? Or is this all a plan to throw us off completely? Only time and continued bridal back-and-forth will tell. Try to keep up. Trust us, it's not easy.
