You can try dresses on in a shop, or you can browse hundreds of styles on your phone. Neither is “better” for everyone. It depends on how much time you have, how sure you are of your style and how comfortable you are ordering a dress you haven’t tried on.
Here’s how they compare.
Shopping in-store
Pros
- You can try the dress on. You see how it fits, moves and looks from every angle.
- True colour and fabric. You can see and feel what you’re buying.
- Staff help. A good assistant can suggest shapes that suit you.
- Take it home straight away, if they have your size in stock.
- Alterations are often available nearby.
Cons
- Limited choice. A shop can only stock so many styles, colours and sizes.
- Often higher prices, because of shop costs.
- Time and travel, and busy weekends in prom season.
- Pressure. It can be hard to decide with a queue outside the changing room.
Shopping online
Pros
- Far more choice in styles, colours and silhouettes.
- Shop any time and compare at your own pace.
- Reviews and photos from other customers.
- Prices are often lower and easier to compare.
- Made-to-measure is much easier to find online.
Cons
- You can’t try it on first. Sizing varies between brands.
- Colour can look different on a screen.
- Delivery time. You need to order in good time.
- Returns can be limited, especially for made-to-measure dresses.
In-Store vs Online: Side-by-Side Comparison
| In-store | Online | |
|---|---|---|
| Choice | Limited to what’s in stock | Hundreds of styles |
| Try-on | Yes | No, so measurements matter |
| Price | Often higher | Often lower |
| Timing | Same day if in stock | Allow for making and delivery |
| Fit | Off-the-peg sizes, alterations extra | Standard sizes or made-to-measure |
| Returns | Usually simpler | Varies, so check before buying |
| Convenience | Needs travel | From home |
Tips for Success: In-Store Shopping
- Shop Early Visit stores several weeks before prom to take advantage of better selection and avoid last-minute rushes.
- Know Your Budget Set a price range before you go to avoid overspending. Factor in alterations and accessories.
- Bring Trusted Companions Bring a friend or family member whose opinion you trust, but remember it’s ultimately your decision.
- Try Multiple Sizes Don’t hesitate to try different sizes. Prom dresses often fit differently than everyday clothes.
- Check Quality Carefully Inspect seams, hems, and fabric for any defects before purchasing.
Tips for Success: Online Shopping
- Read reviews thoroughly. Look for comments on fit, colour accuracy and quality, and for customer photos.
- Understand the returns policy. Check whether the dress is made to order, whether it can be returned for a change of mind, who pays postage and what the time limits are.
- Order in good time. Ask how long making and delivery take, and add a margin. At HappyProm, order about nine weeks before prom in busy season.
- Use the shop’s size chart or measurement guide, not your usual size, and check your order confirmation.
- Pay safely. Pay by card or PayPal where you can, and avoid shops that only take bank transfers.

A third option: made-to-measure online
Some online shops, including HappyProm UK, make each dress to your measurements. That changes a few of the usual trade-offs:
- Fit: the dress is made for you rather than adjusted from a standard size.
- Colour: you can choose from a colour chart.
- Timing: it isn’t instant, so plan about nine weeks before prom in busy season. See when to buy your prom dress.
- Returns: a custom-made dress can’t be returned for a change of mind. At HappyProm, if we make a mistake, email us within 7 days of receiving your dress and we’ll put it right.
Because you can’t swap sizes, accurate measuring matters. See our measurement guide.
Where to buy a prom dress in the UK
Prom dresses come from four main kinds of place:
- Independent boutiques: personal service and try-on, but limited stock, and prices vary a lot.
- High-street and department stores: convenient, and returns on standard items are usually simpler. The prom range tends to be smaller and seasonal.
- Online dress retailers with ready-to-ship stock: wide choice and quicker delivery. Check the size chart and returns policy carefully.
- Made-to-measure online shops, like HappyProm: the dress is made to your measurements and colour choice. It needs more planning time, but you aren’t limited to standard sizes.
Whichever you choose, look for clear policies, real reviews and honest delivery times. Our online shopping checklist shows you what to check.
The best of both: try in-store, order online
Many people combine the two:
- Try shapes in a shop. Find out whether you like A-line, mermaid or a corset bodice, and which necklines suit you.
- Order online in your chosen style, colour and measurements.
Our guide to choosing your prom dress can help you decide before you go.
Shopping online vs in store: which should you choose?
Choose in-store if your prom is close, you want to try before you buy, or you aren’t sure which shape suits you.
Choose online if you have time, want more choice, or want a dress made to your measurements.
Do both if you want to try shapes first and then order exactly what you want.
