Nobody at a wedding can tell what your dress cost. They can tell whether it fits, and whether the fabric moves. Those are the two things to spend on.
There is a particular anxiety about wedding guest dressing, and it is rarely about the wedding. It is about being the person in the photographs who looks like they tried but did not quite get there.
Here is the reassuring part. The things that make a dress look expensive have almost nothing to do with what it cost. They are fit, fabric behaviour, colour, and finish. All four are available at prices that will not make you wince, if you know what you are looking at.
What actually reads as expensive
A hem that is the right length
The single biggest one. A dress hemmed to your own leg looks made for you, and a dress hemmed two inches off looks borrowed. A hem alteration costs very little and takes a week. If you buy one thing and have one thing altered, make it this.
Fabric that moves
Stand in front of a mirror and turn. Fabric that swings and settles reads as costly. Fabric that stays where it is and holds a crease does not. Chiffon, georgette, soft crepe and a good viscose all move. Anything that feels papery between your fingers will look papery in a photograph.
A colour with some depth
Deep colours photograph richer than pale ones at the same price, because a pale fabric shows every irregularity in the weave and a deep one does not. Emerald, wine, navy, plum and forest all do a great deal of work. So does a print, which distracts the eye from the cloth entirely.
Finished edges
Turn the dress inside out in the shop. Seams that are bound or neatly overlocked, a hem with a proper turn, straps that are stitched rather than glued. It takes ten seconds and tells you more than the label.
What to wear, by the kind of reception
An evening reception
A midi or maxi in a deep colour, or something with a little shine. This is the easiest reception to dress for, because low light is generous and a simple shape with a good earring is plenty.
A daytime or garden reception
Print, and length. A floral midi with a flat or low sandal is right almost everywhere, and it handles grass, sun and a long afternoon without any of the three becoming a problem.
A restaurant or small reception
Something simpler than you think. In a small room, a very formal gown feels like a costume. A well-fitted midi in one colour, with the sleeve or the neckline doing the interest, is the register.
A beach or destination reception
Light fabric, long length, and a flat shoe you can actually stand in on sand. Save the heel for the photographs and change into it there if you want it.
Spend the money on the alteration, not the label. It is the only thing in the outfit that is genuinely made for you.
The rules worth keeping
Not white, not ivory, not cream, and not a pale champagne that could be mistaken for either in a photograph. This is the only firm rule and it is worth keeping without complaint.
Not the bridesmaid colour, if you know it. Ask whoever invited you. It is a two-second message and it saves an awkward moment in the group photograph.
Black is fine. The old rule against it has quietly gone, and a black dress at an evening reception is entirely at home. If the wedding is a daytime garden one, a print or a colour will feel warmer.
Read the invitation, then read the venue. A stated dress code is doing exactly what it says. If there is no dress code, the venue tells you. A hotel ballroom and a village hall want different dresses, and the stationery usually gives it away before you have to ask.
Where the budget should go
Put the money into three things and the rest matters far less than you think.
First, the alteration. Already said, still true.
Second, the shoes, and specifically shoes you can wear for eight hours. Nothing undoes a lovely dress faster than the moment you take your shoes off at nine o'clock and carry them for the rest of the night.
Third, one good accessory. A single pair of proper earrings, or one bag that is not obviously inexpensive. One good thing lifts everything around it. Three cheap things do not.
The dress itself can be modest and still be the loveliest thing in the room, provided it fits and it moves. That is genuinely all of it.
The night before
Hang it out, steam it, and try the whole outfit on together. Shoes, underwear, jewellery, bag. It is the only way to find out that the strap shows or the hem catches, and finding out on the night is considerably worse.
Then leave it alone. You have already done the work.
Shapes that work for a reception
A reception involves sitting for a meal, standing for speeches and dancing afterwards, which rules some shapes out faster than any dress code does.
A fit and flare or an A-line is the most comfortable across all three, because the skirt never touches you below the waist. If you want one dress for the whole day, this is the shape.
A wrap dress is the most adjustable and it travels well, which matters if the wedding is a weekend away. It also ties higher or lower depending on how the day is going.
A slip or a column looks lovely and is the least forgiving of a long meal. It is a good choice for an evening-only invitation and a harder one for a full day.
A tiered midi handles heat, grass and a long afternoon better than anything else and photographs beautifully in daylight.
Getting the fit right without spending
Three small fixes cost almost nothing and do most of the work.
Straps that are too long are the most common problem on an inexpensive dress and the easiest to solve. Shortening a strap is a five-minute job and it lifts the whole bodice into place.
A bodice that gapes at the back can be taken in at the centre seam, or held with a small stitch at the point where it opens. Either is invisible from the outside.
A neckline that sits too low can be raised with a couple of stitches at the shoulder seam rather than at the neckline itself, which keeps the line of the dress intact.
None of these are expensive and all of them read as fit, which is the thing people notice.

Common questions
Where to get wedding guest dresses?
Start about six weeks before the wedding, which leaves time for a hem alteration and for returning anything that does not work. When shopping online, look for the shoulder to hem measurement, whether the dress is lined, and a clear photograph of the back. If you can only afford to spend on one thing, spend it on having the hem taken up to your own leg rather than on the dress itself.
What do you wear to a wedding?
Take the lead from the invitation first and the venue second. If a dress code is stated, follow it. If none is given, a midi dress in a colour or a print, with a shoe you can stand in all day, is right at the great majority of weddings. Avoid white, ivory and cream in any form, and check the bridesmaid colour with whoever invited you.
What should a woman wear as a wedding guest?
A midi length dress is the most reliable answer, because it works for a ceremony, a lawn, a dinner and a dance floor without needing a change. Choose a fabric that moves rather than one that holds a crease, and a colour with some depth, which photographs better than a pale one. Add one good accessory rather than several small ones.
The short version
Fit, fabric that moves, a colour with depth, and clean edges. Get the hem taken up, wear shoes you can last the night in, and add one good earring. Nobody at the reception will be able to tell what the dress cost, and every photograph will look like it was made for you.
