Fitting Tips:

Letter sizes (XS, S, M, L, XL) can vary between brands - always check numerical measurements
For tops, if you're between sizes and prefer a fitted look, size down; for a relaxed fit, size up
For trousers, choose your size based on waist measurement first, then consider leg length
Stretchy fabrics offer more flexibility in sizing than structured materials
When in doubt, check the specific garment's fabric composition and fit description
Men's dress shirts are sized by collar and sleeve - measure carefully for the best fit
Athletic or slim fit styles typically run smaller than regular or classic fits

Professional Care Guide - DesignerCentro

Designer T-Shirt Care Guide

Washing Instructions

Machine wash cold (30°C/86°F max) on gentle cycle
Turn t-shirts inside out to protect prints, graphics, and fabric surface
Use mild, color-safe detergent
Wash similar colors together to prevent color transfer
Separate delicate fabrics (modal, bamboo, silk blends) from regular cotton

Drying Guidelines

Air dry flat or hang on padded hangers to maintain shape
Avoid direct sunlight which can fade colors and weaken fibers
Never wring or twist wet t-shirts - gently squeeze out excess water
Reshape while damp to prevent stretching at neckline and sleeves
Low heat tumble dry only if fabric label permits (rare for designer pieces)

Ironing & Steaming

Iron inside out on low to medium heat setting
Use pressing cloth over graphics, prints, or embellishments
Steam lightly to remove wrinkles without direct heat contact
Avoid ironing directly over logos, prints, or decorative elements
Hang immediately after ironing to prevent new wrinkles

Storage Tips

Fold properly using tissue paper between folds for luxury pieces
Hang premium t-shirts on padded hangers to maintain shoulder shape
Store in cool, dry environment away from humidity
Avoid wire hangers which can create shoulder bumps and stretch fabric
Use drawer dividers to prevent overcrowding when folded

Special Care Notes

Pre-treat stains immediately with gentle stain remover
Hand wash vintage or delicate designer pieces in cool water
Professional cleaning recommended for heavily embellished t-shirts
Rotate your collection to prevent excessive wear on favorites
Check care labels as designer pieces may have specific requirements

Fabric-Specific Care

100% Cotton: May shrink slightly - wash cold and air dry
Cotton Blends: Follow general care instructions, less prone to shrinking
Modal/Bamboo: Extra gentle cycle, air dry only
Silk Blends: Hand wash or dry clean for best results
Performance Fabrics: Wash separately, no fabric softener

Print & Graphic Care

Turn inside out before every wash
Cold water only to prevent cracking or fading
Air dry to maintain print integrity
Iron around graphics never directly on them
Store flat if prints are raised or textured

Following these guidelines will preserve the quality, fit, and appearance of your designer t-shirts, ensuring they remain wardrobe staples for years to come.
