2026 TWICE Merch Sizing Guide: Find Your Perfect Fit

Complete Guide Overview

Getting the right size for your TWICE merch makes all the difference. Whether you're ordering your first piece or adding to your collection, this guide breaks down everything you need to know about how TWICE apparel fits, how to measure yourself, and which products run large or small.

TWICE's official merch line, available at the official TWICE store, features a relaxed unisex fit across most items. That means the Classic apparel collection, Premium twice merch store hoodie, Polo Shirt, and Tank Top are all designed to feel comfortable without being baggy or too fitted. But sizing can vary between products, so here's your roadmap to nailing it.

How to Choose the Right Size

Take Your Measurements First

Forget guessing based on the size you wear in other brands. Every brand has its own sizing quirks. Grab a soft measuring tape and follow these steps:

• Chest: Measure around the fullest part of your chest, keeping the tape horizontal and snug but not tight.
• Waist: Measure at your natural waistline, usually just above your belly button.
• Hips: For items like the Tank Top, measure the widest part of your hips.
• Length: From the highest point of your shoulder down to where you want the hem to fall.

Write those numbers down in inches. Then compare them to the size chart on each product page. The TWICE Classic T-Shirt size chart, for example, lists chest measurements ranging from 34-36" for XS up to 50-52" for 3XL.

Product-by-Product Sizing Notes

#### TWICE Classic T-Shirt ($24.99) Made from 100% ring-spun cotton, pre-shrunk, this twice merch store tee has a relaxed unisex fit. It's roomy through the chest and shoulders without being boxy. Because the cotton is pre-shrunk, you won't get surprises after washing. If you're between sizes, size down for a more fitted look - it's designed to be slightly loose. Many fans say it runs true to size for most body types.

#### TWICE Premium Hoodie ($49.99) Our heaviest weight layer. The Premium Hoodie uses a cotton-polyester blend fleece that's soft inside. It's cut slightly larger to accommodate layers underneath. If you want a slimmer fit, go down one size. For an oversized cozy feel, stick with your usual. The hood is generous, and the front pouch pocket is deep enough for phone and wallet.

#### TWICE Polo Shirt ($34.99) This polo is more tailored than the tee. It has a classic collar and two-button placket, made from a cotton piqué fabric. It runs true to size but is less forgiving if you're between sizes - the structured collar doesn't stretch. If you're in between, go up for comfort.

#### TWICE Tank Top ($19.99) A lightweight, sleeveless option. The armholes are cut slightly lower to allow movement. It's made from a cotton jersey blend. Because it's fitted through the bust and ribcage, measure your chest and compare carefully. Many fans size up for a looser fit, especially for layering.

Unisex Fit Explained

Unisex sizing means the garment is shaped for a typical male body (broader shoulders, narrower hips) but is designed to accommodate a range of shapes. For most women and non-binary fans, sticking with your usual size gives a relaxed fit. If you prefer a more fitted silhouette, consider sizing down for the tee and tank, but not for the hoodie or polo.

Also check the length. Unisex tees often have a longer torso than women's-specific cuts. If you're on the shorter side (under 5'4"), the Classic T-Shirt might hit below the hip. That's a popular look, but you can also size down to shorten the length.

Where to Buy Official Merch

Only the official TWICE store guarantees authentic, high-quality merch. Third-party sellers often sell knockoffs with different sizing and lower-grade materials. When you buy from the official store, you get:

• Exact sizing as described in this guide
• Pre-shrunk fabrics that won't warp after washing
• Return or exchange support for size issues (within 30 days)

To see all available sizes and colors, explore the full collection. Each product page has its own size chart with specific measurements. Don't rely on a single chart across all items.

Tips for International Buyers

If you're outside the US, measurements are in inches. Compare your measurements to the chart, not your local size number. TWICE merch ships worldwide, but sizes are based on US standards. For example, a US Large is similar to a UK Large but may be larger than an Asian XL. Always measure.
