Summer Style Forecase: T-shirt and Polo trends to watch in 2025

As temperatures rise and wardrobes shift, T-shirts and polos once again take centre stage. Understanding what’s trending in these staple garments is essential, not just to get the edge but for driving sales and business growth. At Ralawise, we’ve been tracking key industry insights and fashion forecasts to help our customers capitalise on what’s hot in 2025.

From high fashion to high street, let’s explore how the humble tee and classic polo are being reimagined—and how you can make the most of this momentum.


The Return of the Boxy Fit and Retro Aesthetic

In line with *Vogue’s Spring/Summer trend coverage, oversized and boxy silhouettes are dominating the fashion conversation this year. Inspired by ‘90s streetwear and Y2K nostalgia, these looser fits offer both comfort and style for those prioritising ease without sacrificing edge.

T-shirts with dropped shoulders, heavier GSM (200+), and a relaxed fit are seeing increased demand from both retailers and consumers. Styles like the Bella+Canvas Unisex Heavy Boxy Tee (BE155) and Heavy Boxy Long Sleeve Tee (BE156) tap into this trend with their weighty feel and clean, contemporary shape. For an added throwback feel, opt for heavyweight cotton in washed or mineral-dyed finishes—ideal for brands looking to channel a vintage, skater-inspired look.

Colour Watch: From Pastels to Punchy Pops

While neutrals remain strong, we’re also seeing a resurgence in colour for SS25. *WGSN has spotlighted tones like melon, butter yellow, digital lavender, cobalt blue, baby pink, and tomato red as key shades for the season. For polos, especially, colour blocking is making a return where we’re seeing retro tennis club vibes with contrasting collars and cuffs. These nostalgic touches can be a great way to update classic silhouettes for both work and play.

Oversized Streetwear: Bigger, Bolder, Better

Oversized streetwear isn’t just a passing trend; it’s become the uniform of youth culture. Inspired by brands like Fear of God Essentials and Supreme, demand for bold, roomy shapes continues to rise. Unbranded options that offer generous cuts, dropped hems, and space for custom graphics are increasingly sought after by independent labels and creators. Thick ribbed collars, tonal stitching and double-layered fabrics offer the durability that streetwear demands.

Tennis-Inspired Workwear: Smart, Sporty, Polished

As seen in recent collections from Lacoste and AMI Paris, tennis-core is blending preppy aesthetics with relaxed tailoring. Polo shirts are leading the charge with clean white, pastel tones, crisp collars and minimal embroidery. This trend is quickly gathering pace in the workplace. Businesses in a range of industries looking to dress down for summer without losing polish are gravitating towards polos and structured tees in performance fabrics and smart neutrals.

Athleisure 2.0: From Gym to Everyday

Athleisure isn’t new, but in 2025 it’s more versatile than ever. The lines between sportswear, loungewear and casual daywear continue to blur. Performance polos and stretch tees in sweat-wicking or technical fabrics are ideal for both movement and leisure. With inspiration from brands like Lululemon and Alo Yoga, lightweight jersey polos and fitted tees are being styled with everything from tailored trousers to cycling shorts.

Elevated Basics: The Rise of Luxe Minimalism

As seen in *GQ, the shift toward “quiet luxury” is visible every corner of the fashion industry. Consumers are investing in elevated basics that look premium but feel effortless. Pima cotton and organic cotton tees in neutral tones, such as stone, off-white, greys and sage), are particularly popular. For polos, look to pique cotton with subtle texture or modal blends that offer a silky feel and premium drape. Subtle tonal embroidery or matching colour trims add a boutique feel without heavy branding.

Sustainable Choices Are the New Standard

According to a recent *Business of Fashion report, sustainability is no longer a valueadd, it’s an expectation. Gen Z and millennial consumers are more likely to purchase from brands that prioritise ethical production and eco-friendly materials. In the unbranded sector, this translates into increased demand for GOTS-certified organic cotton, recycled fibres, and garments with transparent supply chains. Tees and polos made with eco-conscious practices aren’t just good for the planet - they’re good for business.
