Wikipedia writes of 15th-century fashion:

“Women’s fashions of the 15th century consisted of a long gown, usually with sleeves, worn over a kirtle or undergown, with a linen chemise or smock worn next to the skin. The sleeves were made detachable and were heavily ornamented.The long-waisted silhouette of the previous period was replaced by a high-waisted style with fullness over the belly, often confined by a belt. The wide, shallow scooped neckline was replaced by a V-neck, often cut low enough to reveal the decorated front of the kirtle beneath. Various styles of overgowns were worn. The cotehardie fitted smoothly from the shoulders to the hips and then flared by means of inserted triangular gores. It featured sleeves tight to the elbow with hanging streamers or tippets. The tight fit was achieved with lacing or buttons. This style faded rapidly from fashion in favor of the houppelande, a full robe with a high collar and wide sleeves that had become fashionable around 1380 and remained so to mid-15th century. The later houppelande had sleeves that were snug at the wrist, making a full “bag” sleeve. The bag sleeve was sometimes slashed in the front to allow the lower arm to reach through.”

Wikipedia writes of 15th-century menswear:

“The basic costume of men in this period consisted of a shirt, doublet, and hose, with some sort of overgown (robe worn over clothing). Linen shirts were worn next to the skin. Toward the end of the period, shirts (French chemise, Italian camicia, Spanish camisa) began to be full through the body and sleeves with wide, low necklines; the sleeves were pulled through the slashings or piecing of the doublet sleeves to make puffs, especially at the elbow and the back of the arm. As the cut of doublets revealed more fabric, wealthy men’s shirts were often decorated with embroidery or applied braid.”
