Our meetings vary depending on what Monday of the month it is:

1st Monday of the month: Formal... Dress or skirt, hose, closed-toe shoes. Pin of course!

2nd Monday: Semi-formal... a nice skirt, no hose, shoes can be open-toe.

3rd Monday: Business... Dressy slacks or a skirt.

4th Monday: Open meeting... wear whatever you want!

Our chapter dresses casually for "regular" chapter meetings once a month. Same goes for cultural outings, depending on the outing. For ritual meetings, we wear dressy clothes.

We also wear dressy clothes for special occasions, such as Sweetheart Gala, Founder's Day, Fall Tea and other City Council events.

My chapter has a formal meeting every other week, and informal meetings on the off weeks, though attire is similar.

Formal attire- all black; nice dresses, slacks or skirts with nice heels. The girls are asked to wear colorful jewelry so the black doesn't seem too meloncholy.

Informal attire- nice slacks, capris or skirts with a nice top/blouse and nice shoes (heels). Basically almost like formal dress, except it doesn't have to be all black. No denim.

Occasionally we wear "KD attire" to our meetings, which is a KD shirt of some sort with jeans.

For our Tri Sigma meetings, we wear business attire every week. Once a month we have a ritual meeting where we wear white. Sometimes during the semester, once or twice, we have an informal meeting where we wear letters and jeans.

Our pin attire was either a dress with hose & heels, or good pants suit. We were permitted one informal meeting a month, and the attire depended on the "activity". If we were having a guest speaker, it was still pin attire, although a skirt was allowed. If it was causal (ie: during Recruitment), then almost anything was fair game - as long as you wore some sort of shoes!

Our meetings were casual...whatever you were wearing that day. Officers dressed a little nicer.

Occasionally we'd have theme meetings (like pajama party) and we'd dress to fit the theme.

The majority of Our meetings are causal. with maybe one or two ritual that called for Shirt and Tie.

All of our meeting are Quill attire unless otherwise stated. Before I joined girls said that there used to be one Quill attire meeting and the others casuals.

Counsils are wear what u want.

All of our meetings with rare exception were shirt and tie. There were very specific rules as to dress code. I'm not sure what they do these days.

We have 3 different levels of dress.
Formal Pin Attire is no jeans, cords, khakis or flip flops, and hose.
For Informational or Program Chapter wear it's just no jeans or flip flops.
Fun Chapter we can wear whatever we want.

Dress to pin for weekly business meetings: No denim, chinos, sneakers, or strapless of spaghetti strap tops, shorts/skorts, cleavage, midriff, thighs and butt unexposed, no tee shirts. Pin over your heart, clean, pressed clothes. Tasteful, classic clothing.

For membership education workshops (about one a month or one every couple of months, you were allowed to dress in letters and chinos, and not "dressed to pin.")

Very similar here at Bama as what Adpiucf said. Typical Chapter meetings are pin attire. About once a month we have "informal" chapter meetings with educational seminars and the like, so the dress is casual. Exec Committee meetings and informal standards hearings (now called council meetings) are casual, but Exec Board and Formal Standards Hearings are pin attire.

Currently we are conducting officer candidate interviews and we insist on pin attire for these as well. To me it's just like a job interview and should be treated as seriously. It also says alot about the candidate's personality as to what she feels is appropriate pin attire.

Funny though, the definition of pin attire has changed dramatically since I was in school nearly 20 years ago. Used to be that it was hose and heels. Slacks, no matter how dressy, were a no-no. Now it's pretty much anything goes except no denim (again no matter how dressy), flip flops, spaghetti straps or bare midriffs.

We had casual chapter the first meeting of the month, after that it was badge attire (though this was stretched into business casual occasionally) and then when we had national visits it was FULL badge attire (no lienency). Obviously we wore our magenta catsuits for rituals. :)

The chapter I'm advising now kinda does the same thing, but they are way better at dressing up than my chapter was. I think that is partly due to the whole east coast thing vs. liberal - liberal arts school in the mid-west.

Formal meetings - pinwear

Informal meetings - casual, but no PJ's or workout stuff

Business casual every single Sunday. There's something about dressed up formal that makes you act formal, and that's something we have to do every time to get through a chapter with 17 positions, otherwise chapter will last 5 hours (and often does).
