You have a race day invite. You have no idea what to wear. And PrettyLittleThing has 4,000 dresses that all look the same on a model.
I’ve spent the last two weeks digging through their site, checking dress codes for Ascot, the Kentucky Derby, and the Monaco Grand Prix. Most of what they sell won’t pass inspection. Some of it will get you turned away at the gate.
Here are the seven outfits that actually work. No guesswork.
The Dress Code Trap Most People Fall Into
Race day dress codes are specific. Ascot’s Royal Enclosure requires hemlines below the knee. Shoulders must be covered. No bare midriffs. The Derby is looser but still bans strapless tops and ripped denim. Grand Prix events vary by circuit, but most paddock clubs enforce smart-casual at minimum.
PrettyLittleThing sells clubwear. That’s the problem. Most of their “occasion” section is built for nightclubs, not daytime racing. You need to filter hard.
What You Must Avoid
Anything shorter than 22 inches in the front hem. That’s roughly fingertip length for most women. Ascot stewards measure. I’m not joking.
Sheer panels on the torso. A lace bodysuit under a blazer is fine. A dress with sheer mesh from collarbone to waist will get you denied entry at Royal Ascot.
Spaghetti straps. Unless you bring a jacket or a shawl that stays on. Most people don’t. They get cold, take it off, and suddenly they’re violating the dress code at 3 PM.
The One Rule That Saves You
Buy for the afternoon, not the evening. Race day is 11 AM to 6 PM. That means structured fabrics, covered shoulders, and a hat or fascinator. PLT has decent options if you ignore their “Night Out” tab entirely and search for “midi dress” and “tailored blazer.”
Outfit 1: The Royal Enclosure Midi Dress
The PrettyLittleThing Satin Cowl Neck Midi Dress in Emerald is the single safest bet for Ascot. It hits below the knee, has a modest neckline, and the cowl detail adds structure without being revealing. Price is around $45.
Pair it with a structured blazer in cream or navy. PLT’s Tailored Blazer in Navy ($55) works. It has shoulder pads that give you shape without looking like you’re going to a board meeting.
For footwear: block heels only. Stilettos sink into grass. PLT sells a Clear Block Heel Sandal ($30) that won’t ruin the lawn. Avoid their stiletto mules unless the entire event is on concrete.
Hat: Do not buy your hat from PrettyLittleThing. Their fascinators are flimsy. Spend $40 on Etsy or Amazon for a structured fascinator with a solid base. The one from PLT will wobble after an hour.
Outfit 2: The Derby Day Jumpsuit
The Kentucky Derby dress code is less strict but still expects polish. A jumpsuit is the smartest move because it avoids the hemline question entirely.
PLT’s Wide Leg Satin Jumpsuit in Blush Pink ($50) is a winner. It has a V-neck that’s deep but not vulgar, and the wide leg reads elegant, not casual. Length is full, so no hemline worries.
Add a belt. The jumpsuit comes with a fabric tie, but swap it for a thin leather belt in tan or white. PLT sells a Faux Leather Chain Belt ($12) that cinches the waist properly.
Shoes: pointed-toe flats or low kitten heels. The Derby involves walking on dirt and grass. PLT’s Pointed Toe Kitten Heel Pump in Nude ($28) is fine. Avoid white shoes unless you enjoy cleaning mud off them at 5 PM.
Failure mode: The jumpsuit has a back zip that can jam. Test it before the day. If it sticks, return it. You don’t want to be stuck half-dressed in a parking lot.
Outfit 3: The Grand Prix Tailored Suit
Monaco, Silverstone, or any F1 paddock club demands smart-casual with a sharp edge. Dresses feel overdressed. A tailored suit is the power move.
PLT’s Double Breasted Blazer in White ($60) and matching Wide Leg Trouser ($40) form a suit that works. The blazer has a peak lapel that reads expensive. The trousers sit high-waisted and hit at the ankle.
Wear it with a scoop neck bodysuit underneath. PLT’s Scoop Neck Bodysuit in Black ($15) is invisible under the blazer and keeps your shirt tucked all day.
Shoes: white leather trainers or low-top sneakers. Grand Prix events involve walking on concrete for hours. PLT’s Chunky White Trainer ($35) is fine. Don’t wear heels. You’ll regret it by lap 10.
When NOT to wear this: If the dress code specifically says “day dress” or “racewear,” a suit might read too corporate. Check the invite wording. If it says “smart casual,” the suit is perfect. If it says “race day attire,” go with a dress.
Outfit 4: The Raceday Guest (Budget Under $100)
Not everyone has $200 to drop on a single outfit. Here’s a full look from PLT for under $100 that still passes dress code.
| Item | Product Name | Price |
|---|---|---|
| Dress | PLT Midi Bodycon Dress in Navy | $28 |
| Jacket | PLT Textured Blazer in Ivory | $42 |
| Shoes | PLT Block Heel Sandal in Nude | $22 |
| Bag | PLT Chain Strap Clutch in Beige | $8 |
| Total | $100 |
The bodycon dress is tight but the jacket covers your shoulders and hips. The block heel is low enough to walk in all day. The clutch fits a phone, lipstick, and a card. That’s all you need.
Tradeoff: The blazer is textured polyester. It won’t breathe well in heat. If the forecast is above 80°F, skip the jacket and wear a lace shawl from Amazon instead. PLT’s lace shawls are $10 but look cheap. Spend $25 on a better one elsewhere.
Outfit 5: The Ascot After-Party Dress
Some race days have evening events or after-parties. The dress code shifts from “covered and modest” to “cocktail chic.” You need a dress that transitions without changing entirely.
PLT’s Ruched Satin Midi Dress in Burgundy ($38) does this. During the day, wear it with the blazer from Outfit 1. At 6 PM, ditch the blazer, add a chunky gold necklace, and you’re in cocktail mode.
The ruched fabric hides any food or drink spills. The satin finish catches light well in photos. Burgundy is a strong color for autumn race meets like the Melbourne Cup or Breeders’ Cup.
Shoes: Swap to a strappy heel for the evening. PLT’s Clear Stiletto Heel ($25) is passable for one night. Don’t expect them to last more than two wears. The glue on the clear straps weakens fast.
Mistake to avoid: Don’t wear this dress to a daytime-only event. The V-neck is too deep for Royal Enclosure rules. It’s fine for the Grand Stand or Queen Anne Enclosure, but not the Royal Enclosure.
Outfit 6: The Smart-Casual Derby Guest
Not every race is formal. Local derbies, charity race days, and smaller tracks have relaxed dress codes. You still want to look intentional, not like you rolled out of brunch.
PLT’s Striped Button Front Midi Skirt in Navy/White ($25) paired with a Plain Cotton T-Shirt in White ($12) works. Tuck the shirt in. Add a straw fedora or a wide-brim hat from a different store (again, PLT hats are weak).
Shoes: espadrilles or flat sandals. PLT’s Braided Espadrille Wedge ($32) gives you height without the heel pain. The wedge distributes weight better than a stiletto.
Why this works: The skirt is midi length, so it’s appropriate. The t-shirt keeps it casual. The hat signals you didn’t forget where you were going. It’s a look that says “I tried but I’m not trying too hard.”
When to skip this: If the event has a strict “no denim, no casual footwear” rule, swap the t-shirt for a silk camisole and the espadrilles for loafers. PLT’s Faux Leather Loafers ($28) are a decent alternative.
Outfit 7: The All-Black Raceday Minimalist
Black is the safest color for race day. It hides stains, works in any weather, and photographs well. The risk is looking like you’re going to a funeral instead of a horse race.
PLT’s High Neck Satin Midi Dress in Black ($35) solves this. The high neck is elegant. The satin catches light, which stops it reading flat. The back has a subtle cutout that adds interest without being inappropriate.
Add a wide-brim hat in black or cream. Do not buy from PLT. Their wide-brims flop after one wear. Spend $50 on a proper milliner’s piece or a structured hat from a brand like Lack of Color.
Accessories: gold hoops and a structured clutch. PLT’s Gold Hoop Earrings ($6) are fine for one event. Their Structured Box Clutch in Black ($15) holds your essentials and looks more expensive than it is.
The verdict: This is the outfit for anyone who hates pattern-matching and just wants to look put-together with zero effort. It works for Ascot, Derby, or Grand Prix as long as you add a proper hat. Skip the fascinator with this look. You need the brim for balance.
If you buy one outfit from this list, make it this one. It’s the only one that works for every dress code with the right accessories. Spend the money you saved on a good hat. That makes the outfit, not the dress.
