An excellent source for images of surviving examples of Egyptian clothing and textiles is:

Here is one site with a variety of images either drawn from history of historic costume/fashion books or from actual tomb paintings:

The Eternal Egypt site also has a very brief discussion of clothing.

Another option is to simply look through either history books about ancient Egypt or do a web search for something like "egyptian tomb paintings" or "egyptian statues" and draw inspiration from the original sources. While there is some debate amongst professional scholars as to the accuracy of the depiction of some articles of clothing in ancient Egyptian art (in particular women's clothing), depictions by the Egyptians themselves are your best source.
Overall, the most ubiquitous items of clothing for all classes were:
For men: A simple kilt, usually of linen, reaching to just above the knee with a belt. Belts or girtles for men and women were made of a variety of materials, cloth being the most common. Linen was often used, or woven/braided belts. Leather and beads were also used.
Shirts were worn and examples of these do exist. I believe examples were found in Tutankhamun's tomb, so if you can get your hands on one of the many Tut books floating around, you might find a photo or drawing. The Oriental Institute Museum of the University of Chicago also has an example on display in their Egyptian gallery. Strangely, they are almost never depicted in ancient Egyptian art. This is probably because of the idealizing nature of Egyptian art - in summary, it's always summer :) and also because it would hide the upper body, which is usually depicted as muscular and youthful.
For women: Women also wore kilts (without a shirt) on occassion. Simple sheath dresses were also common, as were dresses with wide bands/straps covering the breasts. Elaborately pleated dresses were popular in the 18th and 19th Dynasties. Female dancers often wore nothing more than a string of beads around their waists.
For children: Children are often depicted in art as having run around naked. Otherwise, they seem to have worn pretty much the same thing as adults.
For everyone: Shawls/mantles of linen or light wool were worn, especially at night or when the weather turned cooler. The popularity of these garments is reflected in the development of a particular category of statuary - the block statue. The inspiration for this type of statue is the pose of a person riding in a sedan chair wrapped in their shawl. The person would sit with their knees up and the shawl wrapped around them, hands resting on their knees or on opposite elbows, giving them a slightly "block" like appearance.
Jewelry of some kind, even if only a single bead or amulet worn on a string, was worn by nearly everyone, even the very poor. Jewelry, or what we call "jewelry" wasn't just for personal adornment - many pieces (amulets) served as protection from evil forces, etc. Popular shapes for amulets include various hieroglyphs, especialy the nfr glyph, animals, and body parts.
Wigs and headgear: Wigs were very popular for men and women. Children are often shown with heads shaved, sometimes with the "sidelock of youth." Facial hair doesn't seem to have been terribly popular, but a few men are depicted with mustaches or beards. The false beard is restricted to the king and deities.
Men and women of high status wore fillets, crowns, etc. The uraeus (snake) was, like the false beard, typically restricted to the king and deities as were various other crowns.
A headcloth was often worn by men.
Specialized people (nobles, the king, queen, priests, deities) often have special identifying garments. The king has his various crowns, occasionally the queen or other royal women wore elaborate crowns. Priests, especially sem priests, wore a leopard skin over their clothing. Viziers are shown as wearing a garment that wrapped around the body at the chest (just below the pectorals or whatever you want to call breasts on men) that reached the ground. It's essentially a huge, long kilt worn Urkel style. (Or so we used to say while studying and trying to be funny.)
If you're curious, the debate about women's clothing tends to revolve around issues of practicality, primarily in the depiction of clothing worn by high status/elite women and goddesses. It isn't clear if women would have worn the extraordinarily tight sheath dresses in which they are often depicted as they would be very restrictive, and some scholars wonder that they could even be achieved with the fabric and sewing techniques available. The argument is that these are idealizing depictions of women intended to accentuate aspects of the body considered important for the function of the art itself - frequently themes of sexuality, fertility, etc.
