So wedding season still has a good two months to go, but  just what do you wear if you are a guest? How to decipher what is appropriate?

The "rules" are different for different times of day, as well as different formalities. In general gals, you'll want to wear a dress. It doesn't need to be full-length unless it's a very formal wedding, and just about any color goes except for white!

We asked a local David¹s Bridal representative for a few esential tips. Check out these crucial dos and don¹ts she had for us and use these celeb styles as a guide:

- For Informal Daytime: Short dress or suit (business attire OK for morning weddings)

- For Informal Evening: Cocktail dress (which is any dressier dress -- for example, a little black dress -- that's not full-length.)

- For Semi-Formal Daytime: Short dress or suit

- For Semi-formal Evening: Cocktail dress 

- For Formal Daytime: Short dress or suit

- For Formal Evening or Black-Tie: Long or dressy short cocktail (beading, glam accessories, wrap)

- For Ultra-formal or White Tie: Long gown, extra glitz (Costume Jewelry, faux diamonds, furs, etc.)

Dos and Don'ts:

- If you have to ask if it's appropriate, it probably isn't. Do use good judgment if the invitation doesn't specify the formality of the event.

- Don't wear white because it competes with the bride, unless you ask her first, as a courtesy. There are plenty of other colors available. This rule may seem outdated, but it's actually just good etiquette to not contend with the bride on her special day.

- Anything too sparkly will make you look overdressed. Don't wear black or sequins during the daytime.

- Don't worry about wearing the same colors as the bridesmaids or mothers. You can't possibly coordinate with everyone in the wedding party.

- Clubwear, overtly sexy clothing (strapless, see-through, etc) doesn't belong at a wedding. A pastel suit or soft floral dress for daytime or a LBD (little black dress) for evening (after 6 p.m.) will take you almost anywhere.

- And casual can mean a pretty sundress (like for a coastal or beach wedding) but rarely means something as sloppy as jeans or shorts, so don't.
