One of the most common mistakes is assuming that a standard menswear size will automatically fit every part of the body correctly.

Other issues can include sizing up to accommodate the bust and ending up with an oversized jacket through the shoulders and waist, choosing trousers that fit the hips but gape at the waist, or focusing too much on a particular size rather than the overall silhouette.

The suit should work around your body rather than requiring your body to adapt to the garment.
