I think a good place to start to get into dress history is general overview of the whole timeline. Understanding especially how the silhouettes change is really important ground knowledge to build the rest of the information on.

I'll start the timeline from Middle Ages and go till the first world war. I'll focus on upper class England/French sector, so keep in mind that before 17th century there were huge regional differences in fashion inside Europe and class differences too. There is a lot variance, changes and nuance inside any century and decade I'm about to discuss, but I'll try to keep this short and introductory and very simplified. I used a very scientific method of basically what makes most sense to me to divide the periods. I've made sketches what I would consider to be the basic silhouette of the period stripped mostly out of the detail and then I give couple of primary source examples.

12th century (Middle Ages)

Dress was simple one or more tunics over a chemise. They were overly long for upper classes, made out of straight lines. There were loose tunics often worn over another tunic, and tunics with laced bodice called biaut. In France bliaut sleeves often widened from the elbow, in England they often widened in frists.

13th century (Middle Ages)

Clothing was mostly very similar as in the previous century, though bliaut was mostly gone and new popular style was a loose sleeves surcoat.

14th century (Middle Ages)

Tailoring basically revolutionized clothing production, since clothes weren't made out of rectangles anymore and could be better made to fit form. Also functional buttons and lacing was popularized resulting in very fitted styles. The underlayer tunic, kirtle, became a fitted supporting layer.

15th century (Middle Ages)

Improvements in weaving technology and trade and growing prosperity in Europe showed in clothing as excess of fabric and variety of trends. Houppelande, a loose A-lined overdress lined with fur and fastened with a wide belt under chest, became a very popular clothing item, and in later decades developed into the iconic Burgundian dress (the red dress). Fitted overdress continued to be popular alongside the warmer houppelandes.

1500s-1550s (Tudor period)

In the renaissance era clothing became increasingly structured and elaborate. The bodice was heavily boned and the skirt was also structured.

1560s-1610s (Elizabethan Era)

Both structuring and elaborate decoration reach it's peak during Queen Elizabeth's reign. She became the defining fashion icon of the late renaissance.

1620s-1670s (Baroque)

In baroque era the bodice was still heavily structured, but more curved than the conical Elizabethan bodice. Otherwise though structuring was replaces with dramatic excess of fabric.

1680s-1710s (Baroque)

In the late 17th century there was a huge shift in the clothing industry as mantua, a loose open robe inspired by Japanese kimono, came to dominate fashion. Rigid bodice was replaces by structured under layer, stays. Stays brought back the conical silhouette of Elizabethan era.

1720s-1780s (Rococo)

Mantua developed into the iconic Rococo dress in France, robe à la francaise (first example picture), and in England robe à la anglaise with closed bodice. Rococo fashion was characterized by the wide silhouette of the skirt.

Nothing brings me more joy than people learning from history and then modernizing it up a bit.

Like you wanna grow your hair long? Stop washing it so often and brush it more to keep it clean. Your hair will be way healthier too. And stop cutting it (and use a boar bristle brush, it’ll work better as it’ll actually absorb the oils, distribute them better, and work a hell of a lot better than non-absorbent plastic would) Edit: Early on, some well meaning person kindly asked me to inform you that the boar bristle brush technique does not work on curly hair, however I have since been informed by multiple parties that it does! My hair is as straight as a pin so use your own judgment!

You want to keep cool in the summer? Out with the polyester and in with the linen and cotton. Natural fibers are going to keep you cooler because they’re literally made to breathe

You want to preemptively stop the underwire in your bra from poking through? There’s a very simple embroidery stitch you can do that the Edwardians used to do to stop their corset boning from coming through.
