Should You Buy a Coat One Size Bigger? Irish Fit Guide

When you step out onto a rainy Dublin street or a windy Galway quay, the question that pops up most often is whether your coat will keep you warm without looking like a bag of potatoes. coat sizing isn’t just about numbers - it’s about how the Irish climate, local style, and everyday activities shape the perfect fit. In this guide we’ll unpack when it makes sense to size up, when you should stick to your true measurement, and how to test a coat in the unique conditions of Ireland.

Why Irish Weather Changes the Fit Game

Ireland’s weather is famously unpredictable. You can start the day with a sunny morning in Cork, get drenched by a sudden shower in Dublin, and end with a crisp breeze off the Atlantic in Donegal. That variability means a coat needs room for:

• Layering a jumper or a Wool sweater on especially cold days.
• Accommodating a waterproof under‑coat when the rain turns into a full‑blown downpour.
• Allowing for movement while walking up the steep streets of Kilkenny or cycling around University College Dublin.

Because of these factors, many Irish shoppers instinctively think a coat a size bigger will give the breathing room they need. But there’s a fine line between comfort and a sloppy silhouette.

How Coat Sizing Works - The Basics

Most brands use chest measurement as the primary metric. A size 40 typically means a 40‑inch chest, but the actual fit can vary dramatically between a sporty outdoor brand and a sleek urban tailor. Here’s a quick breakdown of the most common sizing systems you’ll encounter in Irish stores:

1. European (EU) sizing: Numbers correspond directly to chest circumference in centimeters.
2. British (UK) sizing: Similar to EU but often runs a touch smaller, especially in heritage brands.
3. US sizing: Uses inches and can be generous in the shoulder area.

When you’re shopping on Grafton Street, Dublin’s premier retail strip, you’ll see labels from both European and British manufacturers. Knowing which system a brand follows helps you decide whether to size up.

Pros of Buying One Size Bigger

Choosing a coat a size larger isn’t a decision made lightly, but it can be the right move when:

• Layering is a daily habit: If you regularly wear a thick Aran sweater from Irish Woollen Mills, a larger coat prevents the fabric from pulling at the seams.
\n
• Full‑body movement is essential: Cyclists in the city or hikers on the Wicklow Way need extra room around the hips and thighs.
• Future-proofing: If you anticipate gaining a few pounds during the winter months, a size up can extend the coat’s usability.

In these scenarios, a slightly looser fit can actually enhance the coat’s performance, especially for waterproof shells that need to slide over layers without restricting movement.

Cons of Buying One Size Bigger

On the flip side, a coat that’s too big can look unflattering and waste insulation:

• Cold spots: Loose fabric can create gaps where cold air enters, defeating the purpose of a warm coat.
• Bulky silhouette: Irish street style leans toward a tailored, sleek look. Overly large coats can clash with the clean lines favored in places like Brown Thomas on St. Stephen’s Green.
• Higher laundry costs: Bigger coats use more material, meaning higher dry‑cleaning fees, which matter for students and young professionals in Cork.

Therefore, it’s crucial to balance comfort with a fit that still feels purposeful.

When to Size Up in Ireland - Real‑World Scenarios

Let’s walk through a few typical Irish situations and decide whether a size up is justified.

Practical Tips for Trying on Coats in Irish Stores

Even with a solid plan, the final decision comes down to the fitting room. Here’s a checklist to make sure you get it right:

• Bring your usual winter layers: Slip on a Wool sweater, a scarf, and even a light back‑pack. This mimics everyday wear.
• Check shoulder seams: The seam should sit right at the edge of your shoulder bone. If it drops, the coat is too big regardless of chest measurement.
• Move around: Raise your arms, sit down, and walk a few steps. Any pulling or sagging signals a poor fit.
• Assess the length: For an Irish climate, coats should cover the hips and ideally the upper thighs to protect from rain and wind.
• Ask about alterations: Many Dublin tailors, especially those near Grafton Street, offer quick hemming and sleeve adjustments that can turn a true‑size coat into a perfect fit.

Tailoring and Alterations - The Irish Edge

One of Ireland’s fashion strengths is its tradition of bespoke tailoring. If you land on a coat that’s a size too small, a local tailor can add a few centimeters at the back or adjust the side seams. Conversely, when you buy a size up, a tailor can take in the waist for a sharper silhouette. Shops like Brown Thomas have in‑house alteration services, and independent tailors on the South Quay in Dublin specialise in outerwear.

Quick Reference Checklist

• Know your chest measurement in centimeters (EU) or inches (UK/US).
• Factor in typical layering - add 2‑4cm for a light sweater, 6‑8cm for a thick Aran knit.
• Test shoulder fit first - this never compromises.
• Consider the coat’s purpose: daily commute vs. outdoor adventure.
• Utilise local tailors for a custom finish.
