How to Check Dress Button Quality and Attachment
Short answer: To judge dress button quality, look at the material, the attachment method, and the tension of the threads. Molded plastic buttons crack and chip fastest; resin, corozo, shell, and metal last longer. Sew-through buttons are sewn flat through holes, while shank buttons sit on a raised loop that clears thicker fabric. Test each button by holding the fabric on both sides and tugging in several directions. A button that shifts, or thread that slides, is loose. Also inspect the buttonhole stitching for fraying before you buy.
Sew-through vs shank buttons
There are two main ways a button is attached. A sew-through button has two or four holes in its face, and the thread passes through those holes into the fabric. A shank button has a raised loop on the back, and the thread wraps around that loop. The shank creates a small gap between the button and the garment, which matters on thicker woven fabrics and heavily textured dresses. On lightweight dresses, sew-through buttons are the norm.
The attachment method also affects how the button behaves. A carefully attached sew-through button is sewn with a thread shank: a few extra wraps of thread that hold the button slightly off the fabric, so the fabric does not pull. Look at the back of the button. If the thread is crossed in a neat, consistent pattern and lies flat, the maker took care. If the thread is loose, uneven, or visibly frayed, the button is at risk.
How to test for loose buttons
The fastest test for a loose button takes a few seconds. Hold the fabric firmly on both sides of the button, with your index fingers close to the button itself, and try to shift the button in several directions. A button that moves independently of the fabric, or that exposes thread sliding out of the weave, is not secure. You can also tilt the garment so the button hangs downward: a loose button will rotate under its own weight.
Look at the fabric directly behind the button for signs of strain. If the weave is pulling, or the fabric around the buttonhole is frayed, the fabric may tear before the thread fails, and that is much harder to repair. If the button is loose but the fabric is sound, the fix is simple: replace the button. The problem is when the buttonhole itself is worn, because the damage spreads with every use.
What to pick for your use
Choose button quality based on how you will use the dress. For work dresses and casual dresses that are washed frequently, favor resin or corozo sew-through buttons with tight, bar-tacked thread. For formal dresses, shank or fabric-covered buttons are more refined, but the shank itself must be solid and the fabric around it unmarred.
- Casual and everyday: resin or corozo sew-through buttons, tested with a firm tug.
- Work and frequent wear: resin or shell buttons on a reinforced placket.
- Formal and evening: shank or fabric-covered buttons with a solid shank.
- Wedding guest: dressy buttons that still hold their thread under movement.

Questions
What is the difference between sew-through and shank buttons?
Sew-through buttons have holes in the face and are sewn flat to the fabric. Shank buttons have a raised loop on the back, which creates a gap that helps the button sit correctly on thicker fabric or heavy embellishment. Shank buttons are often used on coats and formal wear, while sew-through buttons are common on dresses.
How can I test if a button is loose without damaging the dress?
Hold the fabric on both sides of the button and gently tug in several directions. If the button moves more than a fraction, or you see thread sliding out, it is loose. You can also lay the dress flat and see if the button rotates on its own. These tests do not harm the fabric.
What causes buttons to fall off?
The most common causes are thread wearing through, a buttonhole that is too snug, or washing the dress in a way that stresses the placket. Back-to-back buttons, especially on fitted dresses, also pull harder. A loose button can be re-sewn, but if the fabric around it is torn, that needs a more involved repair.
Are fabric-covered buttons better than plastic?
Fabric-covered buttons look refined because they match the dress exactly, but the thin fabric can fray at the edges and the inner core can soften after washing. Molded plastic buttons are durable but can crack. For long-term wear, resin or shell buttons are usually a better choice than either covered or molded plastic.
