4. The Structured Trench Coat Layer
One of the most effective styling secrets for maternity fashion is the art of the outer layer. A classic, structured double-breasted trench coat in traditional camel, stone, or deep navy acts as a frame for your silhouette. Worn open, it creates two slimming vertical lines down the front of your body, instantly elongating your frame. Underneath, you can wear a simple maternity bodycon dress or a basic tee-and-leggings combination. The trench coat adds an instant air of European sophistication, making even the most casual lounge pieces look like a high-fashion statement.
