My chapter calls formal "Sapphire Ball" also. But the chapter I advise simply calls it formal. So it's not a Phi Sig wide thing. ;)

Our chapter calls our fall semi-formal the Diamond Cocktail, and our spring formal the Killarney Rose Ball.

we have Winter Formal in fall , and the date dash which replaced our semiformal in spring is called Deepher Dash.

(we're a creative bunch, aren't we?) ;)

We have winter informal and then Starball in spring.

We just call semiformal "semiformal" (in November) and then our formal is called "Saphire Ball" and thats in the spring! :D

Our chapter's formal is the Rose Cotillion

Rose ball in the spring and Fall bash in the fall...not really that creative, hunh?

We have a winter formal which is sometimes called Snowflake ball, but mostly our spring one is "Beaux and Arrows" and is usally on the gateway clipper, the dinner cruise that goes out of Piitsburgh. its way fun

But the most fun i'v EVER had at a formal was at TKE's formal Red carnation ball...those boys know how to party... :)

our's (kappa) is called "sapphire ball"

adpi - black diamond formal
chi-o - eleusinian ball
tri-delt - stars and crescent formal
kd - white rose formal
dg - i think anchor ball

pi kapp - rose ball
sae - sweetheart formal
sigma nu - white rose formal
tke - red carnation ball

I've heard of chapters of Phi Psi and FIJI jointly throwing formals as the Jefferson Duo, both being founded at that school. Same goes for Kappa Kappa Gamma and Pi Beta Phi-the Monmouth Duo. There are many schools around the country where Kappa and Kappa Alpha Theta have a joint dance, Kite and Key, apparently because both were founded on the same day (?).

Same year, 1870.

LXA = White Rose
 

Lambda Chi Alpha will often hold a White Rose Formal. Not all chapters do so, but if there was a more or less universal event it would be split between White Rose & something we call Founder's Day.

As a practical matter, Founder's Day doesn't get anywhere near the support that the formal receives.

Formal
 

Pi Kappa Alpha (I think for most chapters) calls it the Fireman's Ball!

haha, i'm actually drinking out of the "commemorative" glass right now...

not sure why we don't call it fireman's ball
 

we have always called our spring formal the "Dream Girl Formal" because that's when we announce what girl we've chosen. we just have a semi-formal in the fall with no particular name.
