At Cottonwood Bridal, we know your prom dress isn’t just a dress - it’s the dress. The one you’ll take photos in, dance in, and remember forever. That’s why getting the perfect fit is just as important as choosing the perfect style!


Here’s everything you need to know to make sure your prom dress fits flawlessly for your big night.


Start with the Right Size


First things first: don’t get too caught up in the number on the tag. Formalwear sizing often runs differently than everyday clothing, so it’s completely normal to size up. What matters most is how the dress fits your body - not the label.


When shopping, focus on:


A snug (but comfortable) fit through the bust
A natural waistline that hits in the right place
Enough room to move, sit, and dance

Don’t Skip Alterations


Even the most stunning dress may need a little tailoring to feel just right. Alterations are the secret to that custom, made-for-you fit.


Common prom dress alterations include:


Hemming the length (especially for heels!)
Taking in or letting out the bodice
Adjusting straps for support
Adding cups or structure


Pro tip: Schedule your alterations early to avoid last-minute stress.


Bring Your Shoes (and Undergarments!)


What you wear underneath your dress can completely change the fit. When trying on your gown - or heading to alterations - bring:

Your prom shoes (or similar heel height)
The undergarments you plan to wear
Any shapewear or sticky bras you’re considering


This ensures everything sits exactly how it should on the big night.


Move Around Before You Commit


You’ll be doing more than just standing at prom - you’ll be walking, sitting, dancing, and probably taking a lot of pictures.

 

Before saying yes to your dress, make sure you:


Sit down comfortably
Raise your arms and move freely
Walk without tripping or adjusting constantly


If something feels off in the fitting room, it’ll definitely feel off on the dance floor.

 


Plan for Final Touches


A few days before prom, try on your full look - dress, shoes, accessories, everything. This final check helps you catch any last-minute tweaks and ensures total confidence heading into the night.
