You can shop a wide selection of plain white tees on Walmart.com and in many stores. You’ll find options for men, women, and kids in short sleeve, long sleeve, crew neck, V-neck, and multipacks. To narrow it down:

• Use filters: Select size (including Big & Tall and Plus), sleeve length, and fit.
• Check availability: Choose pickup or delivery to see what’s in stock near you.
• Look for project-ready styles: Many listings are labeled for tie-dye or DIY.

Selection varies by location and time. If you don’t see your size in-store, ordering online for home delivery or store pickup can be a convenient alternative.

Start with how you’ll wear your white tee—layering as an undershirt or as a standalone top. Then:

• Measure and compare: Use a soft tape to measure chest/bust and length on a tee you like, then match to each product’s size chart.
• Consider shrinkage: 100% cotton can shrink slightly; if you prefer extra room, consider sizing up.
• Pick your fit: Classic/relaxed for everyday, slim for layering, oversized for a looser look.
• Check lengths: Tall and longer cuts help with torso coverage and tucking.
• Read reviews: Fit feedback can highlight if a style runs small or large.

If you’re between sizes, choosing the larger size can offer a more relaxed feel.

For vibrant, consistent tie-dye results, many crafters prefer 100% cotton plain white tees, especially those labeled as “blank” or “for tie-dye.” Classic-fit crew necks provide an easy canvas. To prepare:

1. Pre-wash: Wash without fabric softener to remove finishes.
2. Dye while damp: Damp cotton can help dye spread more evenly.
3. Protect surfaces: Use gloves and cover your workspace.
4. Set and rinse: Follow your dye’s instructions; rinse until water runs clear.
5. Wash separately: First washes may release excess dye.

Results can vary by fabric and dye type. If opacity or durability matters, a slightly heavier cotton tee may offer a sturdier base.

A few simple habits can help maintain a crisp look over time:

• Sort laundry: Wash whites separately to avoid color transfer.
• Pretreat stains promptly: Apply a stain remover to collars, cuffs, or spots before washing.
• Use the right detergent: A formula for whites and an oxygen-based booster (if the care label allows) can help brightness.
• Choose water and heat wisely: Cool or warm water can reduce fading and shrinkage; tumble dry low or air-dry to help preserve fabric.
• Avoid buildup: Skip heavy fabric softeners if they leave residue; consider a vinegar rinse occasionally if compatible with the garment.

Always follow the care label, as fabrics can respond differently.

Both are great—your choice depends on how you’ll wear the tee:

• 100% cotton: Soft, breathable, and a favorite for everyday wear and tie-dye. It can shrink slightly and may feel heavier in hot, humid conditions.
• Cotton blends: Often lighter, hold shape well, resist wrinkles, and can dry faster. Performance blends may offer moisture-wicking, and some styles include UPF-rated coverage for sun days.
• Weight and opacity: Heavier fabrics typically feel sturdier and show through less; lighter weights are great for layering.

Think about your use—undershirt, workout, or workwear—and check each product’s fabric details and care label to match comfort and durability preferences.
