Between clothing sizes? How to choose your fit
Being between sizes is common. One chart row may match your chest while another matches your waist or hips. There is no universal rule to always size up or always size down.
Find the area that needs room
Look at all the relevant measurements rather than picking a size from a single number. With a fitted woven shirt, the chest and shoulders can limit movement. With trousers, both the waistband and the seat need to work for you.
If the chart does not cover one of your measurements, the nearest highlighted size may still be unsuitable. Consider a different cut or ask the retailer for garment measurements rather than assuming the closest row will fit.
Read the fit and fabric information
A relaxed or oversized garment is designed with more room than a fitted garment. Choosing a smaller size may change the intended length, shoulder position and silhouette as well as its width.
Stretch can affect comfort, but fabric composition alone does not tell you exactly how much a garment will give or recover. Use the product's fit notes and the retailer's advice. Do not automatically subtract a size because a fabric contains elastane.
Check length separately
Going up a size can add length where you do not want it. Compare sleeve, body and leg length where available. Petite, tall or alternative leg lengths may be more useful than a different waist or chest size.
Measure a similar garment you enjoy wearing and compare like with like. Check return costs and conditions before buying. A size estimate is a decision aid, not a substitute for a product specific chart or the option to try a garment on.
