Imagine two antique dresses sitting in front of you, no captions attached. At first glance, they might share similar details: both could be lace, trimmed, with fitted bodices and full skirts. That’s a lot of stuff to keep track of. Forget looking for a date or specific period. Instead, focus on the general silhouette. Where is the dress the widest? Where does the waist sit? How wide are the shoulders? Is the skirt (or trousers) wider or narrower than the top half? These larger proportions are often easier to grasp at a glance than things like embroidery, color, or accessories.
This is because clothes change shape over time with new ways of making them, new fabrics, new undergarments, and new cultural tastes. For example, the way a skirt looks hanging from a crinoline is different from the way it hangs when held out by a bustle. Corsets change how the bodice sits in relation to the waistline and the hips. Sleeves change the look of the shoulders, making them look narrower, rounder, lower, or wider. Try to describe all of those things before you try to identify any of them. It’s better to have a strong sense of where it is than a wrong date.
Pick a picture of a painting or museum piece and ignore the caption. Look at the person from head to toe, and trace the outline of the clothing in your mind. Think about where the shoulders are, if the bodice looks long or short, where the waistline seems to sit, and where the most volume of the skirt is. What does the hem look like? How does everything balance? Does the garment bulge out all around the body, or does it stick out mainly in the back? Write down only what you actually see before you check the label.
All of those decorations get in the way. Lace, ribbons, embroidery, and fancy trimmings appear in lots of different periods. Sometimes styles borrow from earlier fashions. If you focus on one detail, you’ll miss the rest. Decoration comes second. Once you know the broad shape, you can go back to looking at the details like the neckline, sleeves, buttons, fabric, and accessories to confirm what you think.
The most important thing for period recognition is practice. Sometimes you won’t know which two periods you’re looking at are the closest together. Pick two pictures from adjacent decades and put them side-by-side. Don’t try to guess which one is older, just look for the differences in proportion. Maybe the waist changed position, sleeves got wider, the skirt shifted back, or the shoulders and hem were different widths. Keep doing this over and over. Eventually, you’ll build a timeline based on what changed over time, instead of memorizing dates.
The source of the image you’re looking at matters too. A fashion plate shows what the latest styles looked like. A portrait might have been made for a specific reason. A photo might show formal wear instead of everyday dress. A piece in a museum isn’t always typical. You should know the kind of image and garment you’re dealing with before you use it to recognize period.
Finally, you shouldn’t try to memorize the exact dates of every period. Instead, look at the evidence and see if you can support your opinion. If you can find the waistline, shoulders, sleeves, and volume, then say why you think the piece is from one period and not another. Then you can check the actual date and see if your observations were accurate. You aren’t trying to guess the date, just train yourself to notice what you’re seeing.
